Simple and classic, this buttery cinnamon crumb coffee cake is anything but plain! Sour cream ensures a moist, light (not overly dense) breakfast cake, and there’s double the brown sugar cinnamon crumb streusel. Enjoy a thick ribbon of streusel inside and plenty of crumbs on top, both made from the same mixture.
I originally published this recipe in 2015 and have since added new photos and a few more success tips. I’ve also made two small changes to the recipe, which are reflected in the printable recipe below.
Cake for breakfast… well, don’t mind if I do! I’ve published quite a few coffee cake recipes over the years, and this is my go-to, absolute favorite sour cream version.
I’ve made so many variations of this one over the years, including doubling the crumb so there’s more swirl INSIDE and ON TOP of the cake. That’s the version you’ll find in the printable recipe below. (Because what’s the point of crumb cake if it’s all cake and no crumb?! Double the crumb = double the fun!)
One reader, Crystal, commented: “This is delicious! The crumb is surprisingly light and tender… This is my first foray into coffee cake, and I don’t think I need to look any further. ★★★★★”
Another reader, Stacey, commented: “My family loved this recipe! I’ve made MANY sour cream coffee cake recipes over the years. This is by far THE BEST!! ★★★★★”
You Will Love This Cinnamon Crumb Coffee Cake
This cinnamon crumb coffee cake is the original and “plain” version of my raspberry almond crumb cake, cranberry Christmas cake, and blackberry cream cheese crumb cake.
Compared to my New York-style crumb cake recipe, it’s smaller and softer—with a lighter, more cake-like crumb. It also has a delicious cinnamon swirl inside and vanilla icing on top, similar to cinnamon swirl quick bread, cinnamon swirl banana bread, and crumb cake muffins. The best part? Make just 1 cinnamon crumb mixture and use that for the filling AND topping.
- Texture: Tender, fluffy cake paired with a soft crumb topping. Each slice boasts a cinnamon-y ribbon running through the middle.
- Flavor: Classic coffee cake flavors of butter, brown sugar, and cinnamon.
- Ease: Prepare 1 mixture for both the cinnamon swirl and the crumb topping.
This coffee cake is delightful alongside a cup of coffee or tea (or a mimosa!). Make it for a birthday breakfast, a coffee catch-up with a friend, or a morning meeting—really any time you want to make the morning a little special. It’s always a favorite among these Easter brunch recipes, too!
Key Ingredients (Especially Sour Cream!)
- Brown Sugar: Moist brown sugar is the key to a crumb topping that’s soft, not crunchy.
- Flour: All-purpose flour is sturdy enough to support the heavy crumb layer. I was tempted to use cake flour in the recipe to achieve an ultra-soft crumb, but found that all-purpose gave a more ideal texture for a breakfast cake.
- Cinnamon: We can’t have cinnamon crumb cake without it!
- Butter: You need cold butter for the streusel and room temperature butter for the cake. Cream the softened butter with sugar, which produces a wonderfully cakey texture. If you’re a beginner baker, this tutorial on how to cream butter and sugar will be helpful.
- Baking Powder + Baking Soda: These leaveners help the cake rise.
- Salt: Flavor enhancer.
- Granulated Sugar: We’ll cream the butter + sugar together for the base of the cake batter.
- Eggs: Bind ingredients together, and make the cake tender and rich.
- Vanilla Extract: If you have homemade vanilla extract, use it!
- Sour Cream: The magic moist maker! Just like in this white cake, sour cream makes the cake incredibly moist and lush.
- Milk: Just a little to thin out the batter so you can spread it in the pan.
Make the Cinnamon Crumb Mixture First
To keep things simple, there’s only 1 cinnamon crumb mixture. Layer 1 cup (practically half) in the center of the coffee cake and sprinkle the rest on top. You need brown sugar, flour, cinnamon, and cold, cubed butter. The butter must be chilled. Why the emphasis on cold? The streusel mixture needs to maintain some of its structure in the oven or else both layers will sink to the bottom.
Use a pastry cutter to cut the cold butter into the other ingredients. You could also use 2 forks, or a food processor. Look how crumbly it gets:
Expect a Thick Coffee Cake Batter
Refrigerate the crumb mixture as you make the cake batter. The batter is rich and thick, and you need to divide it in half so you can layer in some of the cinnamon crumbs. The old version of the recipe created such a thick, heavy batter that it was difficult to divide and spread into the pan. By adding a little milk (just 2 Tablespoons!), the batter is much easier to divide and spread.
You need an 8-inch square pan for this recipe. See below for other size variations. Line it with lightly greased parchment paper so you can easily remove the cake from the pan as a whole, or just directly grease the pan. (Either way works.) Eyeball half of the cake batter and smooth it into the bottom of the greased pan. It does NOT have to be exact, nor perfect. Layer 1 cup (about half) of the cinnamon crumbs on top:
Now spread the remaining batter on top. This can be tricky since you’re spreading thick batter on an unstable crumb foundation. Just do your best. Top with remaining crumbs:
Bake, and then top with vanilla icing. The icing is optional, but always a fabulous (and pretty) finishing touch. You could even turn it into a delicious orange icing by replacing the milk with orange juice.
Cinnamon Crumb Coffee Cake Success Tips
- Pay attention to ingredient temperature. The butter in the crumb mixture should be cold, and the butter, eggs, and sour cream in the cake batter should be room temperature.
- Do your best to spread the thick batter. The top layer can be hard to spread on top of the cinnamon crumb layer, but it doesn’t have to be perfect. Don’t overthink it.
- Use a metal pan or a glass pan. If using ceramic, the coffee cake may take longer to bake. If using extra dark metal, the cake may take less time.
FAQ: Why Is This Called Coffee Cake?
I get this question a lot. 🙂 There is no coffee IN this cake! “Coffee cake” gets its name not because of the ingredients in the cake, but because it’s a breakfast cake to be enjoyed WITH coffee.
Variations & Different Pan Sizes
- Add some extras! Try it as cranberry Christmas cake (with pecans) or raspberry almond crumb cake; or mix and match your favorite add-ins and flavors. Chocolate chips are always a good idea. (Fold 1 cup/180g into the cake batter.)
- Add a cream cheese layer, like in this blackberry cream cheese version.
- Bake in a 9×5-inch loaf pan—no changes to the ingredients; bake time is about 40 minutes.
- Bake it in a 9-inch round cake pan—no changes to the ingredients and bake time.
- Bake in a 9×13-inch pan—see recipe Notes for exact instructions/ingredient amounts. My team and I tested a few versions of this larger size, so use the precise amounts in the Notes below. This is a wonderful size if you’re feeding a crowd:

Description
Every baker should have a classic, old-fashioned and buttery coffee cake recipe in their back pocket and this one is my gold standard, baseline recipe. You’re welcome to borrow it! An 8-inch square pan is required, but see the recipe Notes for other sizes.
Ingredients
Cinnamon Crumb Mixture
- 2/3 cup (135g) packed dark or light brown sugar
- 3/4 cup (95g) all-purpose flour (spooned & leveled)
- 2 and 1/2 teaspoons ground cinnamon
- 6 Tablespoons (85g) unsalted butter, cold and cubed
Cake
- 1 and 1/3 cups (166g) all-purpose flour (spooned & leveled)
- 1 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
- 3/4 cup (150g) granulated sugar
- 2 large eggs, at room temperature
- 2 teaspoons pure vanilla extract
- 1/2 cup (120g) full-fat sour cream, at room temperature*
- 2 Tablespoons (30ml) milk (any kind, dairy or nondairy, is fine)
Vanilla Icing (Optional)
- 1 cup (120g) confectioners’ sugar, sifted
- 1/2 teaspoon pure vanilla extract
- 2 Tablespoons (30ml) heavy cream or milk
Instructions
- Preheat oven to 350°F (177°C). Line an 8-inch square pan (9-inch square is too big, see Notes for other pan sizes) with lightly greased parchment paper or directly grease the pan. I usually use this square pan or this square pan.
- Make the cinnamon crumb mixture: Combine the brown sugar, flour, and cinnamon together in a medium bowl. Cut in the chilled butter with a pastry cutter or two forks (or use a food processor or your hands) until the mixture is in pea-sized crumbs. Some larger crumbs are OK. You’ll have a little over 2 cups of crumb. Refrigerate until step 5.
- Make the cake: Whisk the flour, baking powder, baking soda, and salt together in a large bowl. Set aside. In a large bowl using a handheld or stand mixer fitted with a paddle attachment, beat the butter and sugar together on high speed until smooth and creamy, about 3 minutes. Scrape down the sides and up the bottom 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 eggs and vanilla, and beat on medium-high speed until combined. Beat in the sour cream. Scrape down the sides and up the bottom of the bowl with a silicone spatula and beat again as needed to combine. Mixture will be lumpy.
- Add the flour mixture to the wet ingredients, and beat on low speed until just combined. Finally, beat in the milk. Do not overmix this batter. The batter will be thick. You’ll have about 2 and 1/2 cups of batter.
- Carefully spread about half of the batter into the prepared pan. Sprinkle 1 cup (about half) of the crumb mixture evenly on top. Carefully spread the remaining batter on top (every last drop of it!). This can be a little tricky since you’re spreading thick batter on top of crumbs, but do your best. I usually use a spoon or small offset spatula. It doesn’t have to be perfect. Sprinkle the remaining crumb mixture evenly on top.
- Bake for around 35–40 minutes or until the cake is baked through. To test for doneness, insert a toothpick into the center of the cake. If it comes out clean, it is done. Allow cake to cool in the pan set on a wire rack for 15 minutes.
- Make the icing: Whisk all of the icing ingredients together. Drizzle over warm cake.
- Lift the cake from the pan using the overhang parchment paper around the sides and slice into squares. Or, if you didn’t use parchment, slice directly in the pan. Serve cake warm or at room temperature.
- Cover leftovers tightly and store at room temperature for up to 3 days or in the refrigerator for up 1 week.
Notes
- Make Ahead & Freezing Instructions: The cake can be baked and covered tightly at room temperature overnight. Make the glaze the next morning and drizzle over cake before serving. Cake, with or without icing, can be frozen up to 3 months. Thaw overnight in the refrigerator and bring to room temperature before serving.
- Special Tools (affiliate links): 8-inch Square Baking Pan (such as this one or this one) | Glass Mixing Bowls | Pastry Cutter | Whisk | Silicone Spatula | Electric Mixer (Handheld or Stand) | Small Offset Spatula | Cooling Rack
- Sour Cream: Sour cream creates a bakery-style tender and thick crumb. Do not skip it. If needed, you can substitute full-fat or low-fat (not nonfat) Greek yogurt.
- Loaf Pan: If you’d like to bake this coffee cake in a 9×5-inch loaf pan, adjust the bake time to about 40 minutes.
- 9-inch Round Pan: This recipe is too small for a 9-inch square pan; however, it fits wonderfully in a 9-inch round cake pan. Same instructions and bake time.
- 9×13-inch Pan: If you want to make this cake in a 9×13-inch pan, you need to just about 1.5x the recipe. My team and I tested the exact amounts and here is what you’ll need. The instructions are exactly the same, just use the following amounts. Crumb: 1 cup (200g) packed dark or light brown sugar, 1 and 1/4 cups (156g) all-purpose flour, 4 teaspoons ground cinnamon, 10 Tablespoons (1 stick + 2 Tbsp or 145g) unsalted butter, cold and cubed. Cake: 2 and 1/4 cups (281g) all-purpose flour, 2 teaspoons baking powder, 1/4 teaspoon baking soda, 1/2 teaspoon salt, 3/4 cup (1.5 sticks or 170g) unsalted butter, 1 cup (200g) granulated sugar, 3 large eggs, 1 Tablespoon vanilla extract, 1 cup (240g) sour cream, 1/4 cup (60ml) milk. The icing recipe makes a lot, so it’s plenty for the larger cake. Bake time is closer to 45 minutes. Makes 24 servings.
- Update in 2022: After making this recipe for 7 years straight, I’ve made 2 small updates to produce an even better sour cream coffee cake. The recipe above has more crumb filling/topping than the 2015 version and it also includes a touch of milk to smooth out the batter. If you wish to make the old version, skip the milk and halve the amounts for the crumb filling/topping.
- Why is this called coffee cake and there is no coffee in the cake? “Coffee cake” gets its name not because of the ingredients in the cake, but because it’s a breakfast cake to be enjoyed WITH coffee.
Reader Comments and Reviews
This cake was Soo good!!
Hi there. Can I make the batter, refrigerate it overnight, and bake in the morning? Thanks!
Hi Ellie, we wouldn’t recommend doing that. Once the wet and dry ingredients are combined, the baking powder and soda start working, so it should be baked right away. Here are the make-ahead instructions: The cake can be baked and covered tightly at room temperature overnight. Make the glaze the next morning and drizzle over cake before serving. Hope this helps!
What is the nutritional value of serving size?

Absolutely lovely recipe! I appreciate that the recipe was adjusted to have more cinnamon mix.
I do not have metal pans, only clear glass, so I extended the bake time to 58 minutes to reach 205F internally.
I anticipate making this regularly for social gatherings.
It was just OK. Thought it was going to taller. It is rather flat.
This recipe turned out delicious. It was a little labor-intensive and I had to drag out the mixer. Using oil and no Kitchaid has spoiled me. I excluded the icing since it was just for the two of us. I like the small yield and I would make the cake again. Thanks so much!
I just made this today and it was so good ! Forgot to add milk but it was still so good!
I don’t bake often but your recipes are always amazing. When looking up any recipe I look for yours first! I became a fan because of the chocolate zucchini cake. Bless you and happy new year!
Best sour cream coffee cake recipe ever! Followed recipe exactly as written, just didn’t add the icing, no particular reason, just didn’t feel like it today! I did have to add a few minutes to baking time, a total of 42 minutes. I also adore your New York Crumb Cake, thanks!
This is by far the best coffee cake I have ever had. My husband and I sat down to have a piece and his comment was, this makes me happy inside. Thank you so much for doing what you do.
I made it twice this week. It came out extra delicious every time. I can’t eat butter as much, so replaced butter with oil in the base. It was still delicious.
Thank you for this recipe.
I just made it with my new Kitchen Aide Blender and I couldn’t wait for it to cool. So delicious, thanks Sally!!!
This cake was awesome! My husband said it was the best cake I’ve ever made!
This was delicious. Late Christmas Eve I needed a Christmas morning treat and had only sugar free vanilla yogurt in the fridge. Turned out great! Next time I’ll use sour cream or plain yogurt and maybe experiment with some orange extract in the drizzle as mentioned on the comments. My family is not big on desserts but there’s only a tiny slice left. Worked great in my 9 inch round pan. Will definitely make again.
Thanks!
Delicious! I baked this in a 9-inch round springform pan and it came out perfectly at 37 minutes. I didn’t have full-fat sour cream so I subbed in the light version. I’m going to try and freeze some of it so I can pull it out for New Year’s.
Tastes great! Easy to follow recipe. Thinking of doing muffins next time just to switch it up.
Incredible recipe! I had no idea what to expect with this but wow, 13/10!!!
I forgot the milk, and slightly over baked it — still the BEST coffee cake I have ever had.
loved it
Loved this recipe, but I add about a 1/4 tsp of fresh ground nutmeg into the batter portion and it has everyone asking “what makes this cake so delicious “?
First time baking a cake from scratch so I had little confidence in myself. I followed the recipe to a T, used a scale to measure the ingredients, and my oh my was it perfection. My entire family raved about how delicious it was and how it just melts in your mouth. 10/10 would recommend, even for beginners. This is definitely a keeper! Thank you Sally
Such a great and easy recipe. I added pecans because we love nuts!
Wonderful recipe. Cake was so tender and the topping was so good. We loved it!
Just made this for a Christmas breakfast. It turned out delicious and everyone loved it!
Hi, can I make this without eggs? Just substitute with more sour cream?
Hi Aarti, the eggs give necessary structure to the cake, so we don’t recommend replacing them with more sour cream.
I just made this tonight to have w breakfast with my mother tomorrow morning. I couldn’t resist taking a lil taste ahead of time whe still warm..OMG the tender crumb on this thang! Thank you so much I will be making this often for my fam & friends
I love how much cinnamon it has throughout the cake! It was a hit! I have been asked to make this for Christmas morning.
This is phenomenal!!! I’ve made so many times. I am gluten free and just sub in King Arthur Measure for Measure GF Flour blend. It works great and the coffee cake is so addictive!!
I would like to make this in a Bundt pan. Can you suggest amounts for recipe? Thx
Hi Mws, there isn’t enough batter for a Bundt pan. However, if you try the 9×13-inch pan recipe/ingredient amounts (in the Notes), that would likely be enough. We’re unsure of the best bake time.
