These easy lemon bars are loaded with fresh citrusy flavor with a buttery shortbread cookie crust. You only need 4 ingredients for the lemon curd filling! Creamy, tangy lemon bars are the perfect lemon dessert for summer potlucks and BBQs.
If I had to choose a favorite from my lemon dessert recipes, these bright, sunshiney lemon bars with a perfect shortbread cookie crust would be a top contender. These are the BEST lemon bars. On the bottom is a sturdy shortbread crust with the perfect thickness. On top of that is a perfectly baked lemon layer that’s extra bright and lemony (the most lemony lemon bar you’ll ever find!).
A light sprinkle of powdered sugar tops them off. Absolute PERFECTION! If you love desserts like my lemon cheesecake bars and lemon crinkle cookies, these lemon bars are bound to be a hit.
What Makes these the BEST Lemon Bars?
- Buttery shortbread crust. The crust is the same one I use for my pecan pie bars, and it’s truly the perfect base for these lemon bars! I’ve mastered the crust so it’s delicate and crunchy, but not flimsy.
- Only 4 ingredients. The creamy lemon curd filling comes together in a snap with simple ingredients, including fresh lemons.
- Thick, but not eggy. I’ve eaten lemon bars with a filling that tasted eggy, or the filling glooped all over when I went to cut the bars. Not these lemon bars! The filling is thick and creamy, but all you taste is delicious citrus!
- Easy to make. With only 10 minutes of prep, this lemon bar recipe couldn’t be easier. It’s a classic for a reason, and I just know you’re going to want to whip these up for every potluck, BBQ, or just because!

Ingredients You’ll Need
The ingredients list for these lemon bars is super simple, with very common pantry items. And fresh lemons, of course! Scroll down to the printable recipe card for the complete details and exact measurements.
SHORTBREAD CRUST
- Unsalted butter – Soften the butter, but do not melt it.
- Powdered sugar – I love the lighter texture that the powdered sugar gives to the crust. Granulated sugar will also work, in a pinch.
- All-purpose flour – Butter, sugar, and flour. That’s the makings of a simple shortbread crust.
- Kosher salt – EVERY shortbread crust deserves a touch of salt!
LEMON curd FILLING
- Eggs – You’ll need 6 eggs for this recipe, a main ingredient when making lemon curd.
- Granulated sugar – This not only adds sweetness to the lemon mixture, but also helps to thicken it.
- Lemon juice – Only freshly squeezed lemon juice will do! This will give you the brightest, freshest flavor.
- Lemon zest – The secret to my extra lemony lemon bars is EXTRA lemon zest. If you adore lemon as I do, you’ll LOVE this! (Here’s the zester we use, one of my favorite kitchen tools.)
- All-purpose flour – Provides stability to the creamy lemon curd filling.
How to Make Lemon Bars
This easy lemon dessert recipe features two distinct layers: a delicious shortbread crust and a bright, creamy lemon curd filling. Grab two bowls and a baking pan, and let’s make these bars!
- Prepare the crust. Combine butter, flour, powdered sugar, and salt in a large bowl. Pat evenly into your prepared pan.
- Pre-bake crust. Bake at 350° F until set and just beginning to turn color, 15 to 20 minutes.
- Prepare the lemon filling. Beat together the eggs, sugar, lemon juice and zest, and flour. Pour over the warm pre-baked crust.
- Bake. Place in a 350°F oven and bake 30 to 35 minutes, or until the center is set and no longer jiggly. Afterward, let the lemon bars cool completely to room temperature. I usually let the pan sit on the counter for 1 to 2 hours, and then put it in the refrigerator to chill for 1 to 2 hours more.
Slicing and Serving Lemon Bars
Before serving, I like to give the bars a dusting of powdered sugar. Either sprinkle powdered sugar over the whole pan before cutting, or sprinkle it over individually cut bars. I also prefer to eat the lemon bars chilled, or at least slightly chilled. This gives them a firmer texture.
Want super clean cuts? Bake the lemon bars in a pan lined with parchment paper. Once cooled, pull the bars out of the pan using the parchment paper overhang and place the whole slab on a cutting board. Cut into squares with a long, non-serrated knife, and wipe it clean between each cut.
Tips and Tricks
- Use powdered sugar in the crust. Powdered sugar is not as dense as granulated sugar, which gives the crust a more delicate texture. This crust is the perfect thickness, with an almost melt-in-your-mouth kind of texture!
- Pre-bake the crust. This gives the crust a head start, which guarantees a properly baked crust that can hold up the creamy lemon layer.
- Use only fresh lemon. To achieve the extra tangy lemony goodness in this recipe, use only fresh lemon juice. And add every last bit of lemon zest that the recipe calls for – I know it seems like a lot – but this is the key for that extra hit of lemon flavor.
- Do not reduce the sugar in the lemon filling. The sugar not only sweetens the fresh tart lemon filling, but also works with the eggs to thicken it. Reducing the sugar will give you a looser filling that will not set up as well.
Make-ahead
You can prepare these bars one to two days ahead of time. Bake as directed and allow the pan of bars cool to room temperature. Then, cover the bars with an airtight lid or tight-fitting plastic wrap, and refrigerate.
Before serving, remove the pan of lemon bars from the fridge. If any condensation has formed on the top of the bars, blot the bars with a paper towel. Proceed with cutting the bars and sprinkling with powdered sugar.
How to Store
- Refrigerate. If you won’t be eating all the lemon bars on the day they are baked, you should cover them tightly and refrigerate them. They’ll stay fresh for up to 4 days. If any condensation forms on top of the bars, simply blot it off with a paper towel before sprinkling them with powdered sugar. I don’t recommend storing these on the counter.
- Freeze. Lemon bars are one of my favorite desserts for freezing. To freeze them, let the pan cool completely, and slice the bars. Store the bars in an airtight container, with wax paper between layers. Freeze for up to 3 months and defrost the bars in the fridge or at room temperature. Add a fresh dusting of powdered sugar, and enjoy!

Lemon Bars
Ingredients
for the crust:
- 1 cup unsalted butter softened (not melted)
- 2 cup all-purpose flour
- 1 cup powdered sugar
- ⅛ teaspoon kosher salt
for the lemon filling:
- 6 large eggs
- 3 cup granulated sugar
- 4 tablespoons grated lemon zest – here’s my favorite zester
- ½ cup fresh lemon juice
- 1 cup all-purpose flour
Instructions
- Preheat oven to 350° F. Lightly spray a 9″ x 13″ glass or ceramic baking pan with cooking spray. Or for clean cuts: line the pan with parchment paper, leaving an overhang on the long sides – and then use the sides to lift the finished bars out for easier cutting. Set aside.
For the Crust
- In a medium bowl, combine the butter, flour, powdered sugar, and salt. Mix with a large spoon or your fingers until well combined. Shape the dough into a ball and then pat it evenly into your prepared pan. Bake for 15 to 20 minutes, or until set and just beginning to turn color. Remove from oven.
For the Lemon Filling
- While the crust is baking, prepare the lemon filling. With an electric mixer on medium speed, beat together the eggs, sugar, lemon zest, lemon juice, and flour. Pour mixture over the warm baked crust and bake for an additional 30 to 35 minutes, or until the center is set and no longer jiggly. The top should be lightly golden brown.
- Remove the pan from the oven and let the bars cool completely at room temperature. I usually let them cool on the counter for about 2 hours and then put the pan in the refrigerator to chill for 1-2 hours.
- I recommend serving these chilled or even just slightly chilled. Once cool, dust with powdered sugar and cut into squares. Or cut into squares and then dust with powdered sugar. If lining the pan with parchment paper, cut around the edges of the pan to loosen, pull the bars out of the pan using the overhang on the sides, and place on a cutting board. Cut into squares with a long, non-serrated knife and wipe the knife clean between each cut. Finish with a dusting of powdered sugar
Notes
- Although you don’t want to over-bake, you don’t want to under-bake either, as the lemon filling will not set up properly. My oven bakes a bit on the light side, and I always bake this for 35 minutes. If you find that the bars didn’t fully set, don’t give up on this recipe. Give it another try and increase the baking time. It will work!
- I prefer to store these bars in the refrigerator, pull them out about 10 minutes before serving, and enjoy them with a slight chill. They also freeze well!

How many bars dones this make
Hi Brenda – the recipe card states 24 servings, that’s bars cut about 2″ in size. But you can cut them into whatever size you like.
Your recipe for lemon bars calls for 6 eggs to make the lemon filling. Should it be 6 egg YOLKS instead of 6 eggs? (I read that this makes a lemon “curd,” but I think a lemon curd uses mostly egg yolks.
Hi Cathy – this recipe is correct as written = 6 eggs, to include both yolks and whites.
Best Lemon Bars on the Planet
Yummy lemon bars, loved your recipe too. Thanks for sharing.
Thank you! Enjoy!
Hahaha! I’m looking capable and qualified with my beautiful lemon squares. I’ve used this recipe time and time again. I have found that for me, using Meyer lemons isn’t a good idea. They added additional sweetness and didn’t give me the punch of lemon flavor that regular lemons did.
I literally have probably made 20 different lemon bars from 20 different recipes and these were the best by far!! No runny filling…no doughy crust..they were perfect. The recipe is spot on. Thank you for sharing!!!
Your comment made me smile – thanks, Hayley. I’ve made these so many times over the years, always get asked for the recipe. Enjoy!
My grown daughter loves lemon. I made these for her birthday after comparing different lemon bar recipes I looked up online. These turned out great. The only thing I changed was the sugar in the crust- I used mostly granulated and some confectioners. I used the juice and zest from 2 lemons, which was plenty. The bars baked 30 minutes and set beautifully! Another recipe I saw added a lemon glaze drizzle icing , but these are sweet enough! Saving this recipe! Thanks.
I’m so glad you liked these lemon bars – I get alot of requests for the recipe whenever I take them anywhere!
2 lemons would perfectly for me too. My boyfriend has never had one and was blown away. I’ve had store bought ones but even being my first time making em, I believe I have a new keep on hand recipe. Thanks
Yay!!!! I hope you enjoy many more homemade lemon bars in your future!
Hands down best lemon bars ever!!! Easy to make and were a huge hit this easter. Thanks for sharing. Elizabeth
This is the best recipe for lemon bars I’ve come across! Most recipes call for 2 T of lemon juice-no lemon flavor! The amount of zest is perfect. I’m always on the lookout for a lemony lemon bar, and this fits the bill! I have made 3 batches in the last couple of weeks for various events, and receive raves every time! Thank you so much!
I’m so glad you agree! I think far too many lemon bars are wimpy on that bright lemon flavor. Enjoy many more tangy lemon bars!
Do you chill the baked crust at all before pouring the filling or just add and bake immediately? These look great!
Hi Brenda
I made Lemon Squares for a friends birthday during the week and I got a gooey mess. I could only cut the edges into squares,the middle I had to throw away. I found your website and thought I’d try your Lemon Bars-seeing as you said they will definately set. I made them tonight and have just sliced them and they are perfect. Tastes great and presentation is 100 times better than my previous effort.Looks just like the photo-a rare thing for me!!! Thank you so much. I can’t wait to try your other recipes.
