This towering chocolate chip cake combines a soft vanilla cake crumb and sweet whipped vanilla buttercream with oodles of mini chocolate chips. For a finishing touch that elevates this cake to showstopper status, top it with a chocolate ganache drip. Watch the video tutorial for a complete walk-through of the recipe and demonstration of how to do the ganache drip topping.
One reader, Traci, commented: “This cake is a triple threat! Amazing cake, decadent frosting, and ganache! Wow! So fun and easy to make! Huge hit! ★★★★★”
Another reader, Lora, commented: “Made this cake for my daughter’s birthday and it was delicious! The cake had wonderful buttery but light flavor, and the ganache layer was perfectly rich. ★★★★★”
Q: How do you improve on the perfect white cake? A: Add chocolate chips! Because after all, why let the chocolate chip cookies have all the fun? Chocolate chips are great in cakes, too! (And both can be true at once: have you made this chocolate chip cookie layer cake before?)
My versatile white cake was yet again my starting point for developing a new layer cake recipe. That cake is my definition of *cake perfection* and has become one of the most popular cakes on my website. I’m even including it in my upcoming cookbook. Here’s why:
- Soft & airy crumb
- Fluffy, but not eggy
- Pure sweet vanilla flavor
- Perfect base for pretty much any flavor of frosting
- Stick-to-your-fork moist & tender
- Converts easily to a quarter sheet cake
In today’s version, we’re adding chocolate chips, and portioning the batter between 3 8-inch round cake pans. You can, of course, stick with 2 9-inch round cake pans like the original version. But no matter what you do, don’t skimp on the fluffy buttercream and decadent chocolate ganache drip!
Key Ingredients for Your Chocolate Chip Cake
- Cake Flour: Cake flour is almost 30x finer than all-purpose flour. Using it is a surefire way to achieve a delicate, soft-as-silk texture. It’s sold in the baking aisle and you can use the rest of the box in any of these recipes that use cake flour, including my popular confetti cake.
- Proper Room-Temperature Butter: To achieve a good rise, properly cream the butter and sugar together. You have the crutch of baking powder and baking soda, but the cake’s crumb truly sings when that creaming process steps in. You need softened, room-temperature butter, which is actually still cool and firm to the touch. Butter that’s too cold or too warm won’t mix properly. If you’re interested in learning more, here’s a helpful video and tutorial for how to cream butter and sugar.
- Egg Whites: Do not use egg yolks. Using only egg whites ensures that the crumb is not weighed down by the fat in egg yolks. Think about it: lighter confections such as angel food cake require only the egg whites. Same is true here. Use 5 large egg whites in this cake. If you need an idea of how to use the leftover egg yolks, try making a batch of lemon curd!
- Pure Vanilla: Reach for pure vanilla extract—a full Tablespoon goes in the cake batter, and then you’ll use it to flavor the buttercream frosting, too. You’ll really taste it in this recipe, so I don’t recommend using imitation vanilla here.
- Sour Cream Instead of Egg Yolks: Sour cream is the cake’s security blanket. While it contains fat like the egg yolks would, it won’t weigh down the crumb. It adds moisture and richness, and makes for a creamy, tender texture in every bite.
- Mini Chocolate Chips: For the best texture (and the most chips in every mouthful!), use mini chocolate chips in the cake and frosting. If using regular chocolate chips, they are more prone to sinking in the cake layers.
Start by Making the Chocolate Chip Cake Layers
The cake batter follows a simple, familiar process. Whisk the dry ingredients together, then work on the wet ingredients. In a separate bowl, use a mixer to cream the butter and sugar together. Beat in egg whites, then the sour cream and vanilla. Pour in the dry ingredients and then with the mixer running, slowly add the milk. Finally, fold in the chocolate chips by hand or with the mixer on low speed.
Expect a creamy, slightly thick batter, and then divide between your cake pans:
Use Parchment Paper Rounds for Cakes
Lining cake pans with parchment rounds is the trick I use every single time I bake a round cake, whether I’m making a 1-layer sprinkle cake, a 9-layer Smith Island cake, or today’s recipe. Store-bought pre-cut parchment rounds are convenient, but it’s really easy to just make them yourself. You can cut the exact pan size you need, whether you’re making a 6-inch cake, an 8-inch cake, or a 9-inch cake. If you don’t make a lot of round cakes, just cut them as you need them. If you bake a lot, cut many at a time and store them with your baking pans, ready for the next time you bake.
Very lightly grease the cake pan with butter or nonstick spray. Place the parchment paper round inside, and then grease the parchment, too. Yes, you grease the pan and then also grease the parchment. This creates an ultra-nonstick environment for your cake. The cake won’t stick to the pan, and the parchment round won’t stick to the cake. For more tips on this method, see Parchment Paper Rounds for Cakes.
Once the cakes have baked and cooled, trim the tops using a cake leveler or a large serrated knife to create an even surface. A flat top ensures a sturdier and more stable layered cake. Check out this detailed how to assemble and decorate a layer cake post for helpful tips!
Whipped Chocolate Chip Buttercream
To fill and assemble today’s towering cake, I took the whipped vanilla buttercream from my vanilla sheet cake recipe and scaled it up to coat this 3-layer 8-inch chocolate chip cake. And since this is a chocolate chip cake, I couldn’t resist folding chocolate chips into it. Taste testers (and there were dozens after making about 6 of these!!!) didn’t seem to mind the extra chocolate. 😉
It’s whipped, fluffy, and positively loaded with chocolate chips:
Success Tip: If you want to save some buttercream for piping on top (like the photos and video show), set some aside before you beat in the mini chocolate chips. You wouldn’t want to try to pipe the chocolate chip buttercream because the chips could clog the piping tip.
Assemble the cooled cake layers with the frosting. I use about 1 cup of frosting between each layer—just eyeball it.
Absolutely No Need for a Crumb Coat
In most of my layer cake recipes, I recommend applying a crumb coat: a thin layer of frosting on the exterior of the cake that locks in any loose crumbs and helps stabilize the layers. However, for this chocolate chip layer cake, we’re skipping that step. Because of the lumpy chocolate chips, it would be hard to spread the frosting thin enough to make a crumb coat. The other thing we’re doing differently today is not running a bench scraper around the sides of this cake to smooth out the frosting, because it would only drag the chocolate chips around. Instead, I use a large flat icing spatula to apply the chocolate chip buttercream on the sides.
2-Ingredient Chocolate Ganache
Easily one of the most versatile toppings/fillings in the dessert world, chocolate ganache is quick and simple to make. You need a 1:1 ratio (by weight) of just two ingredients:
- Heavy Cream or Heavy Whipping Cream: Make sure the word “heavy” is in the title/on the carton. Do not use half-and-half, whole milk, or any other liquid because the ganache won’t set up properly.
- Chocolate: You can use semi-sweet chocolate (recommended) or bittersweet chocolate.
Chocolate Ganache Drip Cake Decoration How-to
Refrigerate the cake for at least 20 minutes before adding the chocolate drip. You want the frosting to be fairly cold before you top it with the warm chocolate ganache, so the chocolate begins to set as it drips down the sides of the cake.
Make the chocolate ganache in a glass liquid measuring cup with a pour spout, to make it easy to transfer it into the squeeze bottle.
Go around the perimeter of the top of the cake in a zigzag motion, squeezing the bottle so the chocolate comes out and drips down the sides of the cake. Work quickly, because as the ganache cools, it begins to thicken, and we don’t want that happening in the squeeze bottle. After you’ve gone all the way around the edge, squeeze the remaining chocolate ganache on top of the cake, and use an offset spatula to smooth it out.
Refrigerate the cake again for at least 20 minutes to set the ganache before slicing.
If the chocolate ganache thickens in the squeeze bottle before you’ve finished using it all, place the bottle in large bowl/container filled with very warm water. Let it sit for 5 to 10 minutes until it thins out again.
Yes. If you don’t have a squeeze bottle, you can use a piping bag with a small round tip, or a zipped-top plastic bag with a corner snipped off. You could even just use a spoon, but it will take a bit longer.
I reserved some buttercream to pipe on top of the cake as an optional garnish (before adding the chocolate chips). I used a Wilton 1M piping tip. You can absolutely do that, or you can top with more chocolate chips, fresh berries, or crumble up the cake scraps you leveled off the top of the cake layers.
Make This as a 6-Inch Cake, 9-Inch Cake, or a Sheet Cake
This is a tall, rich cake that serves a lot of people, and I know that many bakers don’t want to make such a large cake. Instead, you can use 6-inch cake pans and make this chocolate chip layer cake as a 6-inch cake; or you can make a 9-inch 2-layer cake, or a 9×13-inch quarter sheet cake. Here are instructions for each:
- 6-Inch 3-Layer Cake: Follow all the same directions for the 6-inch vanilla cake recipe in the recipe card here, and add 3/4 cup (135g) mini chocolate chips (still tossed in a Tablespoon of flour) to the batter, and 3/4 cup mini chocolate chips to the frosting. For the ganache drip topping, decrease the amounts to 4 ounces (113g) chopped chocolate and 1/2 cup (120g/ml) heavy cream.
- 9-Inch 2-Layer Cake: Make the cake batter as instructed below, and divide between 2 greased and lined 9-inch round cake pans. Extend the bake time to 26–28 minutes. Keep the frosting and ganache amounts the same.
- 9×13-inch Sheet Cake: Make the cake batter as instructed below, and pour/spread it in a greased metal or glass 9×13-inch baking pan. Bake for 34–36 minutes, until a toothpick inserted in the center of the cake comes out clean. For the frosting, use the whipped vanilla buttercream amounts from this vanilla sheet cake recipe, and add 3/4 cup (135g) mini chocolate chips. For the ganache topping, you can make it as written below, or decrease the amounts to 4 ounces (113g) chopped chocolate and 1/2 cup (120g/ml) heavy cream for a thinner layer. Follow the same instructions for the ganache, including refrigerating the cake before and after topping, but instead of transferring ganache to a squeeze bottle, simply pour and spread it evenly over the frosting.
Here’s the sheet cake version:

Description
This towering chocolate chip layer cake combines a soft vanilla cake crumb and sweet whipped vanilla buttercream with oodles of mini chocolate chips. For a finishing touch that elevates this cake to showstopper status, top it with a chocolate ganache drip. Watch the video tutorial for a complete walk-through of the recipe and demonstration of how to do the ganache drip topping. For other size cakes using this recipe, see Notes below.
Ingredients
Cake
- 2 and 1/2 cups (285g) cake flour (spooned & leveled)
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon salt
- 3/4 cup (12 Tbsp; 170g) unsalted butter, softened to room temperature
- 1 and 3/4 cups (350g) granulated sugar
- 5 large egg whites, at room temperature
- 1/2 cup (120g) sour cream, at room temperature
- 1 Tablespoon pure vanilla extract (yes, Tbsp!)
- 1 cup (240ml) whole milk, at room temperature
- 1 and 1/4 cups (225g) mini chocolate chips tossed in 1 Tablespoon cake flour
Whipped Chocolate Chip Buttercream
- 1 and 1/2 cups (340g) unsalted butter, softened to room temperature
- 5 and 1/2 cups (650g) confectioners’ sugar
- 1/3 cup (80ml) heavy cream (can be cold or room temperature)
- 1 and 1/2 teaspoons pure vanilla extract
- 1/8 teaspoon salt
- 1 cup (180g) mini chocolate chips
Chocolate Ganache
- 6 ounces (170g) semi-sweet chocolate, finely chopped
- 3/4 cup (6 ounces or 170–180g/ml) heavy cream
Instructions
- Preheat oven to 350°F (177°C). Grease three 8-inch round cake pans, line with parchment paper rounds, then grease the parchment paper. Parchment paper helps the cakes seamlessly release from the pans. (If it’s helpful, see this parchment paper rounds for cakes video & post.)
- Make the cake: Whisk the cake flour, baking powder, baking soda, and salt together. Set aside.
- Using a handheld or stand mixer fitted with a paddle attachment, beat the butter and sugar together on high speed until combined and creamy, about 3 minutes. Scrape down the sides of the bowl with a silicone spatula as needed. (Here’s a helpful tutorial if you need guidance on how to cream butter and sugar.) Add the egg whites. Beat on high speed until combined, about 2 minutes. Then beat in the sour cream and vanilla extract, again on high speed, until the mixture comes together. Scrape down the sides as needed. Add the dry ingredients and turn the mixer on low speed. With the mixer running on low, slowly pour in the milk until combined. Do not overmix. You may need to whisk it all by hand to make sure there are no lumps or dry pockets at the bottom of the bowl. The batter will be slightly thick. Fold in the mini chocolate chips.
- Pour batter evenly into cake pans. Weigh them to ensure accuracy, if desired. Bake for 24–26 minutes or until the cakes are baked through. To test for doneness, insert a toothpick into the center of the cake. If it comes out clean, it’s done. Or you can lightly poke the top of the cake with your finger. If it bounces back, it’s done.
- Allow cakes to cool in the pans set on a cooling rack for 1 hour, then remove them from the pans and let the cakes finish cooling directly on the rack. The cakes must be completely cool before frosting and assembling.
- Make the buttercream: (Note that if you want to pipe plain buttercream on top of the cake like in the photos and video, set around 3/4 cup (about 180g) aside before adding the chocolate chips.) In a large bowl using a handheld mixer or stand mixer fitted with a paddle attachment, beat the butter on medium to medium-high speed until smooth and creamy, about 2 minutes. Add confectioners’ sugar, heavy cream, vanilla extract, and salt. Start the mixer on low speed, then gradually increase to high speed and beat until whipped and fluffy, about 4 minutes. Fold in the mini chocolate chips, either by hand with a spatula, or you can beat them in on low speed until they’re evenly dispersed throughout the frosting.
- Assemble and decorate: Using a large serrated knife, slice a thin layer off the tops of the cakes to create a flat surface. Discard the scraps, or you can save them to crumble on top of the finished cake. Place 1 cake layer on your cake stand, cake turntable, or serving plate. Evenly cover the top with about 1 cup of frosting. Top with 2nd cake layer, upside down, and evenly cover the top with another 1 cup of frosting. Top with the third cake layer, either right side up or upside down. Spread the remaining frosting all over the top and sides. I use and recommend a large, straight icing spatula to apply the frosting.
- Refrigerate the cake for at least 20 minutes, or up to 8 hours. The frosting must be cold when you add the chocolate drip on top.
- Make the chocolate ganache: Place chopped chocolate in a medium heat-proof bowl with a pour spout (I use a 2-cup glass liquid measuring cup). Heat the cream in a small saucepan over medium heat until it begins to gently simmer. (Do not let it come to a rapid boil—that’s too hot!) Pour over chocolate, then let it sit for 2–3 minutes to gently soften the chocolate. With a metal spoon or small rubber spatula, very slowly stir until chocolate has melted and mixture is smooth. The finer you chopped the chocolate, the quicker it will melt with the cream. If it’s not melting, do not microwave it. If needed, see Troubleshooting Chocolate Ganache. Once ganache mixture is smooth, transfer it into a squeeze bottle.
- Chocolate ganache drip: Remove the cake from the refrigerator. Working in a zigzag motion, gently squeeze the warm ganache around the edge of the cake, turning the cake as you go. See video tutorial below as a visual. The ganache should drip down the sides and set as it does. When you’ve gone around the whole cake, squeeze remaining ganache on top of the cake, and smooth it into an even layer with an offset spatula. Feel free to garnish with fresh berries, chocolate chips, or leftover cake crumbles from leveling the tops of the cakes. Chill, uncovered, for at least 20 minutes, or up to 6 hours before slicing and serving. Once the ganache has chilled, if you set aside buttercream in step 6, you can pipe it on. I used Wilton 1M piping tip.
- Cake can be served at room temperature or chilled. I prefer it at room temperature. Cover leftover cake tightly and store in the refrigerator for up to 5 days. I like using a cake carrier for storing and transporting.
Notes
- Make Ahead & Freezing Instructions: The cake layers can be baked, cooled, and covered tightly at room temperature overnight. Likewise, the frosting can be prepared and then covered and refrigerated overnight. Bring the frosting to room temperature when ready to assemble the following day. Frosted cake can be frozen up to 2 months if you have room in the freezer. Thaw overnight in the refrigerator and bring to room temperature before serving.

- Cake Flour: If you can’t find cake flour, here is a DIY homemade cake flour substitute you can use instead.
- Carton Egg Whites: You can use carton egg whites. The carton should give measurements for substituting for fresh egg whites.
- Milk, Sour Cream, Substituting Buttermilk: Whole milk and sour cream are strongly recommended for the best taste and texture. A full-fat plain yogurt would work instead, though the cake may not be as light. Same goes for a lower-fat milk. If you want to use buttermilk, the best way to do so is to have it replace both the sour cream AND milk in this recipe. Use 1 and 1/2 cups of buttermilk, then leave out the sour cream and whole milk.
- If Using Regular Chocolate Chips: If you use regular chocolate chips instead of mini chocolate chips, they are more likely to sink in the cake layers, even after tossing in flour. I have better success using mini chocolate chips.
- Chocolate: Ganache will only set if the correct chocolate is used. You can use high-quality chocolate chips if needed (I prefer Ghirardelli or Guittard semi-sweet chocolate chips), but I recommend using chocolate baking bars, in either semi-sweet or bittersweet. You can find them right next to the chocolate chips in the baking aisle. They are usually sold in 4-ounce (113g) bars. I like Baker’s or Ghirardelli brands.
- 3-Layer 6-Inch Cake Instructions: You can use 6-inch cake pans and make this chocolate chip layer cake as a 6-inch cake. Follow all the same directions for the 6-inch vanilla cake recipe in the recipe card here, and add 3/4 cup (135g) mini chocolate chips (still tossed in a Tablespoon of flour) to the batter, and 3/4 cup mini chocolate chips to the frosting. For the ganache drip topping, decrease the amounts to 4 ounces (113g) chopped chocolate and 1/2 cup (120g/ml) heavy cream.
- 2-Layer 9-Inch Cake Instructions: Make the cake batter as instructed above, and divide between 2 greased and lined 9-inch round cake pans. Extend the bake time to 26–28 minutes. Keep the frosting and ganache amounts the same.
- 9×13-Inch Quarter Sheet Cake Instructions: Make the cake batter as instructed above, but pour/spread it in a greased metal or glass 9×13-inch baking pan. Bake for 34–36 minutes, until a toothpick inserted in the center of the cake comes out clean. For the frosting, use the whipped vanilla buttercream ingredient amounts from this vanilla sheet cake recipe, and add 3/4 cup (135g) mini chocolate chips. For the ganache topping, you can keep the amount as is for a thicker layer, or decrease to 4 ounces (113g) chopped chocolate and 1/2 cup (120g/ml) heavy cream for a thinner layer. Follow the same instructions for the ganache, including refrigerating the cake before and after topping, but instead of transferring ganache to a squeeze bottle, simply pour and spread it evenly over the frosting.
- Chocolate Frosting Alternative: This cake also tastes amazing with chocolate frosting instead. Follow the frosting recipe from my triple chocolate layer cake recipe. It’s enough for today’s 3-layer cake. Feel free to fold in chocolate chips!
Reader Comments and Reviews
Chocolate Chip layer cake is complete and picture submitted. Every thing turned out well, the chocolate chips did not sink. I followed the directions and was not disappointed. The cake is extremely rich and a small slice with satisfy your sweet tooth.
Beautiful and delicious cake! The mini chocolate chips in the icing and cake were a fun crunchy addition to cake. All my chocolate chips sank to the bottom of each layer, so I’m anxious to try it again and see if I can get them better dispersed.
These lava cakes were delicious and easy to prepare. Served with vanilla ice cream and a homemade whiskey caramel drizzled on top. Will make again.
Nice, moist cake. The chocolate chips sank to the bottom of the layers and the ganache was too runny; but neither affected the taste. Most of the family thought it was too sweet, but still delicious.
Wow! I loved this cake! It was absolutely delicious. It was much better than I imagined. The icing recipe didn’t make enough for the extra swirls on top but it was fine. The ganache drip was a fun, new challenge for me. I would definitely make this again and it was fun for Valentine’s Day.
I made this for my Galentine’s Day party and all my girls a LOVED IT.
It was challenging but so worth it. It turned out beautifully and taste amazing! It’s one of the best cakes I’ve ever eaten!
I tried to make this in 3 6in pans. After 26 mins, the cakes weren’t even close to cooked all the way through. Once I finally did take them out, they sunk a lot. Any ideas where I went wrong in this recipe?
Hi Sarah, how tall were your pans? If they had shorter sides, were they overfilled by chance? Overmixing the batter can also cause cakes to turn out squat and dense, which could be the culprit for the sinking cakes.
Delicious cake!! The drip was tricky for me, but I always struggle with ganache. So good and rich. My friend didn’t believe I made it!!
Great cake recipe. I will definitely make it again.
The cake was fun to make and delicious. The whipped buttercream was the perfect icing for this.
The peanut butter lava cakes were simple to make and delicious! The saltiness of the peanut butter paired well with the semi sweet chocolate!
This month’s challenge was time consuming but so worth every minute.
My family really enjoyed this Chocolate Chip Cake with Ganache Drip.
Yummy! I struggled with the chocolate drip. I tried copying the zigzag motion from Sally’s video but it just kind of sat in the zigzag pattern without dripping down the side. Maybe my ganache was too cool when I started? Any tips?
This cake was great! I made it with my best friend, and we had a great time! We subbed large choc. Chips for mini, and it still came out great! Highly recommended, Thanks Sally!
I enjoyed making this cake. I’m a chocolate chip lover. I hope the ganache isn’t too much. I have not tried it yet.
The peanut butter lava cakes were simple to make and tasted amazing! Loved the saltiness of the peanut butter with the semi sweet chocolate!
This cake is so interesting to make and tastes great. I am inexperienced in making buttercream frosting and found that process challenging.
I made the sheet cake version of this because I knew I would be sharing with neighbors and figured it would be easier to share than a layered cake! The recipe was easy to follow. This wasn’t my personal favorite cake, but the neighbors all loved it! Thanks for another fun challenge!
I made this cake for a party and it vanished very quickly! I got so many rave reviews on it. It also looks very impressive. The chocolate chips did sink even though a put flour on them. I saw this happened to a lot of people. It surely didn’t affect the final product, though!
Cake in general is probably my least favorite dessert but this one was amazing! It was just the right amount of chocolate, not overly sweet, and so moist! I was pleasantly surprised! I forgot to coat the chocolate chips with the cake flour but I didn’t notice them really sinking
This chocolate chip cake was so very delicious. It was moist and fluffy just like a cake should be. Sally does it again ❤️
It was very good. I would make it again.
The chocolate chips did settle to the bottom of the cake for me, but I didn’t do the best job making sure I coated them well in flour. All in all, a very good recipe.
Another super easy and tasty recipe from Sally! I’ve made her white cake a few times before and adding the mini-chocolate chips was a fun twist!
Had to make it a a 2 layer 9 inch cake since I don’t have 3 – 8 inch pans, but this was a super fun bake and delicious to boot. My family has now claimed they all want this as their birthday cake! Even my husband who has never once stayed from a German Chocolate Cake for his birthday said he wants this one this year!!
I was so excited about this challenge! Had a little trouble with the drip. But it was fun!!❤️
Super yummy and pretty, and simple enough to make without being an ordeal. I am addicted to Sally’s Baking Addiction!
This cake baked up soft and fluffy! The flavors are like a chocolate chip cookie in cake form. The ganache drip is the best part.
It was super fun to make. The taste was just ok for me. My cake turned out quite dense…probably just me!
