Lemon Bars with Shortbread Crust

You only need 7 ingredients to make these lemon bars. The lemon curd filling is extra thick and creamy and sits on an irresistible buttery shortbread crust. Always bake lemon bars at a lower temperature to avoid over-baking. They’re simply the best lemon bars and are perfect for picnics, bake sales, spring brunches, baby showers, and bridal showers.

Today I’m teaching you how to make lemon bars. I love this lemon dessert recipe so much that I published it in my 1st cookbook, Sally’s Baking Addiction. These are the best lemon bars and I don’t use that statement lightly. After 1 taste, I’m confident you’ll agree. Everyone needs this recipe.

The process is pretty simple and I’m walking you through each step in the video tutorial below. Pick up some fresh citrus and let’s get baking. Spring is in the air!

Video Tutorial: Lemon Bars

These are classic lemon bars featuring a soft butter shortbread crust and a tangy sweet lemon curd filling that’s baked to the perfect consistency. The lemon layer is thick and substantial, not thin or flimsy like most other lemon bar recipes.

Only 7 Ingredients in these Lemon Bars

  1. Butter: Melted butter is the base of the shortbread crust.
  2. Sugar: Sugar sweetens the crust and lemon curd filling layers. Not only this, it works with the eggs to set up the lemon filling. If reduced, the filling will be too wet.
  3. Flour: Flour is also used in both layers. Like sugar, it gives structure to the lemon filling. These days, I add slightly more flour to the shortbread crust compared to my cookbook version. You can get away with 2 cups, but an extra 2 Tablespoons really helps solidify the foundation of the lemon bars.
  4. Vanilla Extract: I use 2 teaspoons of vanilla extract in the shortbread crust. Not many lemon bar recipes call for vanilla extract and I promise you it’s my best kept secret.
  5. Salt: Without salt, the crust would be too sweet.
  6. Eggs: Eggs are most of the structure. Without them, you have lemon soup!
  7. Lemon Juice: I highly recommend using lemon juice squeezed from fresh lemons. You can also use another citrus like blood orange, grapefruit, or lime juice. For extra flavor, add some fresh zest as well.

How to Make Lemon Bars in 5 Steps

  1. Prepare the crust: Mix all of the shortbread crust ingredients together, then press firmly into a 9×13-inch baking pan. Interested in a smaller batch? See my recipe note.
  2. Pre-bake: Pre-baking the crust guarantees it will hold up under the lemon layer.
  3. Prepare the filling: Whisk all of the filling ingredients together. No cooking on the stove!
  4. Bake: Pour the filling on the warm pre-baked crust, then bake for around 20 minutes or until the center is just about set. I slightly increased the baking temperature from my cookbook version. Either temperatures work, but 325°F is preferred.
  5. Cool: I usually cool the lemon bars for about 1 hour at room temperature, then stick the whole pan in the refrigerator for 1-2 more hours until relatively chilled. They’re wonderful cold and with a dusting of confectioners’ sugar on top!

Prepared in only 2 bowls and a baking pan, clean up is a breeze. These lemon bars win 1st place every time because they’re the perfect balance of tangy and sweet. In fact, I made them for my friend’s baby shower last weekend and they were the first dessert to disappear. And that’s saying a lot considering the competition: homemade chewy fudgy frosted brownies and adorable mini animal cracker cookies. 🙂

2 Guaranteed Tricks to Make the Best Lemon Bars

  1. Use a glass pan. Ceramic is fine, but glass is best. Do not use metal. I always detect a slight metallic flavor in the lemon bars when baked in metal pans.
  2. Use fresh juice. Store-bought bottles are convenient, but you miss out on a lot of flavor. You will definitely taste the difference! I have a super old citrus juicer, but I recently purchased this juicer for my mom and she loves it. Highly recommended.

White Air Bubbles on Top of Baked Lemon Bars

Do you notice air bubbles, perhaps even a white layer of air bubbles, on top of your baked lemon bars? That’s completely normal. It’s the air from the eggs rising to the surface. Some batches have it, some don’t. Regardless, the lemon bars taste the same and a dusting of confectioners’ sugar covers it right up!

Description

You only need 7 ingredients to make these lemon bars. The lemon curd filling is extra thick and creamy and sits on an irresistible butter shortbread crust. Always bake lemon bars at a lower temperature to avoid over-baking. See recipe notes for important tips. They’re simply the best lemon bars and are perfect for picnics, bake sales, spring brunches, baby showers, and bridal showers.


Ingredients

Shortbread Crust

  • 1 cup (16 Tbsp; 226g) unsalted butter, melted
  • 1/2 cup (100g) granulated sugar
  • 2 teaspoons pure vanilla extract
  • 1/2 teaspoon salt
  • 2 cups + 2 Tablespoons (265g) all-purpose flour (spooned & leveled)

Lemon Filling

  • 2 cups (400g) granulated sugar
  • 6 Tablespoons (46g) all-purpose flour
  • 6 large eggs
  • 1 cup (240ml) fresh lemon juice (about 4 lemons)
  • 2 teaspoons fresh lemon zest, optional
  • optional: confectioners’ sugar for dusting


Instructions

  1. Preheat the oven to 325°F (163°C). Line the bottom and sides of a 9×13-inch glass baking pan (do not use metal) with parchment paper, leaving an overhang on the sides to lift the finished bars out (makes cutting easier!). Set aside.
  2. Make the crust: Mix the melted butter, sugar, vanilla extract, and salt together in a medium bowl. Add the flour and stir to completely combine. The dough will be thick. Press firmly into prepared pan, making sure the layer of crust is nice and even. Bake for 20-22 minutes or until the edges are lightly browned. Remove from the oven. Using a fork, poke holes all over the top of the warm crust (not all the way through the crust). A new step I swear by, this helps the filling stick and holds the crust in place. Set aside until step 4.
  3. Make the filling: Sift the sugar and flour together in a large bowl. Whisk in the eggs, then the lemon juice and lemon zest (if using) until completely combined.
  4. Pour filling over warm crust. Bake the bars for 22-26 minutes or until the center is relatively set and no longer jiggles. (Give the pan a light tap with an oven mitt to test.) Remove bars from the oven and cool completely at room temperature. I usually cool them for about 2 hours at room temperature, then stick in the refrigerator for 1-2 more hours until pretty chilled. I recommend serving chilled.
  5. Once cool, lift the parchment paper out of the pan using the overhang on the sides. Dust with confectioners’ sugar and cut into squares before serving. For neat squares, wipe the knife clean between each cut. Cover and store leftover lemon bars in the refrigerator for up to 1 week.
  6. Freezing Instructions: Lemon bars can be frozen for up to 3-4 months. Cut the cooled bars (without confectioners’ sugar topping) into squares, then place onto a baking sheet. Freeze for 1 hour. Individually wrap each bar in aluminum foil or plastic wrap and place into a large bag or freezer container to freeze. Thaw in the refrigerator, then dust with confectioners’ sugar before serving.

Notes

  1. Special Tools (affiliate links): 9×13-inch Glass Pan | Glass Mixing Bowls | Silicone Spatula | Silicone Whisk | Juicer | Fine Mesh Sieve
  2. Halve the Recipe: Halve each of the ingredients to yield around 12 squares in a 9-inch square baking pan. Same oven temperature. Bake the crust for 16-18 minutes and the bars for 20 minutes or until the center no longer jiggles.
  3. Sifting: More often than not, the flour doesn’t fully incorporate into the lemon filling unless it’s sifted with the sugar. As directed in the recipe, sift the two together before adding the eggs and lemon juice. I don’t always do this (and didn’t even do it in the video above!) but it’s preferred to avoid any flour lumps. If you have a sifter, it’s worth using. If you forget, it’s not a huge deal. Here is my favorite sifter. You use it again to dust the lemon bars with confectioners’ sugar.
  4. Lemon Juice: For exceptional taste, I highly recommend fresh lemon juice. Here is a wonderful inexpensive juicer if you don’t have one. Or use another fresh-squeezed citrus like grapefruit, blood orange, lime, or regular orange. You can slightly reduce the sugar if using a sweeter citrus. I recommend no less than 1 and 2/3 cup granulated sugar in the filling as it’s needed for structure.
  5. Room Temperature: Bringing the eggs and lemon juice to room temperature helps them mix easier into the flour and sugar. However, I never notice a taste or texture difference when using cold. Room temperature or cold, use whichever!

    Hi Sally, I made this recipe last week and it was a huge hit! Thanks so much for sharing!

    I did have kind of a weird question – I was wondering if you knew if the base of these could be made in muffin tins? I’m trying to create something similar to a lemon bar in “cup” form but with a filling consisting of lemon curd, raspberry coulis, and creme pat! (It’s kind of a bizarre question and I get that it’s a reach of an ask!)

      I haven’t tried it but please do and report back! You can try to push the dough up the sides of the muffin tin to create the cups, if they don’t maintain their shape you can always press the middle down right after they come out of the oven. They sounds like they would be great!

    If you got anything besides perfection with these lemon bars, it was probably baker error. Baking time was spot on and the flavor amazing. Not usually a lemon fan, but the lemon flavor wasn’t overpowering at all. Thank you thank you thank you. We’ll definitely make again!!

      Bars were delicious. However, the top was so moist that the powdered sugar dissolved. Should I blot them before putting sugar on? Thanks.

        That’s the nature of lemon bars because the curd is so moist. Blotting them a little bit first always helps though!

    These are EXCELLENT! I’ve spent the last few days scouring the internet and searching through all my cookbooks to find the perfect lemon bar recipe for Easter dinner. I decided on these and I’m so glad I did. Everyone raved about them. These were simple to make and taste like classic lemon bars with the perfect balance of sweet and tart. I also loved the addition of vanilla in the shortbread. I made a regular batch and a gluten free/dairy free batch. To both, I added the zest of one lemon (I like it really lemony) with the lemon juice and eggs.

    To make them gluten free/dairy free, I used the King Arthur one to one gluten free flour blend for the shortbread. I also subbed Earth Balance for the butter and used only 1/4 tsp salt (Earth Balance butter substitute is salty as is). For the lemon filling, I used 2 TBS arrowroot powder in place of 6 TBS flour. They turned out perfect and I couldn’t tell the difference.

    Thank you for sharing this delightful recipe!

    I can’t wait to try this recipe! My friend made some for Easter yesterday, claiming a reknown status of them, and we were all so excited! She even knew the recipe in her head. Well…. they weren’t quite all that. Now that I see this recipe, I know she didn’t have enough eggs or lemon juice in the recipe, and her sugar amounts were all off. She even put powdered sugar in the crust recipe and it was very dense, even kind of hard. Of course I told her they were delicious! It was nice to offer to make them for us. 😉 😉

    Hi Sally!
    I used your recipe to make lemon bars for my family and friends, and they came out great! I’m new to baking, so I’m very proud of myself. 🙂 I’m wanting to bake another batch with a different crust, maybe a graham cracker crust. What are your thoughts on how many graham crackers and how much sugar and butter I would need for a 9×13 pan?

    I made these this weekend and they were WAY too sweet and WAY too much lemon. They turned out perfect consistency-wise when I added 5 minutes to both the crust bake time and the bar bake time. But the flavor of sugar and lemon were overpowering.

    I am a bourgeoning baker and have never made lemon squares (or left a comment on a baking website). I tend to stick with chocolate desserts. I was a bit intimidated but these were amazing. A-mazing. The BEST i have ever had (not exaggerating)in my life. I am in Mexico and did use límon which are like tiny limes because lemons are harder to come by. I REALLY appreciate your detailed recipes and explanations of the “why” and how certain ingredients interact or affect the outcome and how to account for variations. Thank you for all the thought you put into these recipes. I also did your peach cobbler which was a HIT! I didnt taste it. That’s the only reason i cant personally comment on its level of amazing. Cant wait to try more. This is my new favorite recipe site!

    I’m planning on making these this weekend for Easter, and I was wondering if you might be able to answer a question for me. I was thinking a meringue on top of these – would you lower the amount of sugar in the bars since meringue can be pretty sweet, or make as is? Also, would you lower the baking time by 10 min, add the meringue, and then bake for that extra 10 minutes?

    These look delicious, and I can’t wait to try them!

    1. Sally @ Sally's Baking says:

      Hi Jennifer! I recommend sticking to the recipe no matter what you are topping the bars with. I think topping with the meringue 10 minutes before they’re finished baking is the best idea. However, you may want to bake the bars plain for at least 15-18 minutes first– when the meringue covers it, it will slow the filling from cooking through. 25-28 minutes total would be ideal.

    I’m sorry but these tasted like a sweet lemon omelette. The taste and texture of the eggs was so strong that I had to throw it all away. I’m not sure how you can put 6 eggs in there and not have it smell and taste like eggs of course, but oh well.

      Hi Lili! The baked lemon filling should be creamy and moist, it shouldn’t taste like an omelet. If it does, it’s been over-baked. Sorry you had trouble with this recipe!

    Hi Sally!!
    I made these lemon bars as is for the challenge last month & they were AMAZING!! After reading through the comments & seeing that someone brought up passion fruit I just knew I had to try it so I made them again yesterday subbing out the lemon juice for passion fruit juice making no other changes. They are FANTASTIC!! I used the passion fruit pulp that comes frozen (no seeds) & just thawed & strained it. SO SO yummy!! I also wanted to note that for both versions my crust & filling took a little longer than the recommended bake times to be done (at the 325 oven temp).
    Thanks so much for this delicious recipe Sally!! 🙂

    I followed the recipe almost exactly and they turned out great! I did find that I needed about 5 large lemons to get 1 cup of juice. The crust to filling ratio was perfect. The only thing I changed was the sugar itself. I recently started baking with Lakanto and so I used half sugar and half Lakanto, and NOT ONE person could tell the difference. It reduced the calories by about 1000 as well (bonus!) Great recipe!

    These were delicious and super easy! I used meyer lemons from Trader Joe’s so they were a bit sweeter, which I appreciated. The shortbread crust is really what made this stand out to me! I baked in a 9×13 glass dish and needed to bake an extra 10 minutes for it to be set (my oven runs a bit hot, so i never have to leave things in longer than called for). The teachers at my kid’s school loved them!

    Such an easy and delicious recipe! The original lemon recipe was fantastic; my church potluck loved it!

    I tried it with lime also, and grapefruit…lime was better, as grapefruit gave a weak taste for some reason. The second time I reduced the grapefruit and added lemon to the grapefruit and it came out better. Looking forward to experimenting further!
