This easy Lemon Bars recipe has just the right ratio of buttery shortbread crust and creamy lemon curd filling. They have the perfect creamy, sweet and tanginess that makes it hard to stop at just one.

I have so many favorite bar recipes, like these Key Lime Pie Bars, S'mores Bars, Butterfinger Bars, and White Texas Sheet Cake.

Three homemade lemon bars stacked on top of eachother.

Why I love this recipe:

  • Basic pantry ingredients: There are only a few ingredients needed to make these homemade lemon bars including flour, sugar, butter, lemon juice, salt, baking powder and eggs.
  • Chewy shortbread crust: The best lemon bars are extra thick, soft and chewy, all made possible by the texture of the shortbread crust.
  • Creamy lemon filling. The filling is perfectly sweet and creamy, with the perfect amount of lemon tartness.

How to make Lemon Bars:

Shortbread Crust: In a mixing bowl or the bowl of a stand mixer, cream together the butter and powdered sugar. Add the flour and salt then mix on low speed, just until combined.

Press dough evenly into the bottom of an 8″ pan with parchment paper, or a greased dish. Bake for 10 minutes then remove from oven and set aside.

Make Filling: While the crust cools, make the lemon filling. Mix the lemon zest and sugar in a mixing bowl then add the lemon juice, flour, baking powder, and eggs. Mix until well combined and the sugar is dissolved then pour mixture over crust.

Bake lemon curd bars at 350 degrees for 35-40 more minutes, or until the filling has set. Remove from oven then allow to cool completely.

Can I not use the lemon zest?

The lemon zest really gives these their distinct lemon flavor so I wouldn’t advise leaving it out.

Not for nothing, but I’ve always found lemon extract to be a perfectly serviceable substitute for zest. Rate of one teaspoon per zested lemon called for.

The only reason I did not give 5 stars is because I believe the ratio of filling to crust is a little off. I read one review that said a lady doubled the recipe for the filling because her husband requested it, and I completely understand why. The flavor is superb – fresh, not too sweet (although I did cut back a little on sugar), twangy enough to taste real lemon. Crust flavor & consistency is spot on too. I just think the crust should complement the lemon flavor, but I think this thickness overpowers it a bit. I will double the filling next time I make, and I WILL make it again! This one is definitely a keeper. Thank you for sharing!

These ARE perfect! I made them exactly as written, and they were wonderful! Today, I am using the same crust, but doubling the filling, at my husband’s request. I’m sure they will be yummy. The fresh lemon juice and zest really makes these bars special!

I do half the amount of sugar usually because I don’t like my lemon bars too sweet. Great Recipe!

Baked these today as part of my Christmas baking. Lemon bars are always a tradition around Christmas in my family, along with way to many other sweet treats. The flavor of these are perfect. I should have baked them about 10 minutes longer as they weren’t quite finished in the center. I also doubled the recipe and cooked in a 9×13, so that could also account for why they would have been better cooked for 30 minutes instead of 20. It was my first time cooking lemon bars (my late grandma used to make them and were one of her favorites) so I thought they looked done but the center was still slightly gooey. They will surely get eaten either way. Ive tried many of your recipes and not one I haven’t thoroughly enjoyed, thank you Lauren!

My husband loves lemons, and he loved these! The other day day when I was out walking a lady gave me some lemons so this was perfect!

first batch never set I am curious as to how cool the shortbread has to be before putting filling on top?

I picked a couple of lemons from my son’s Myer lemon tree while visiting in SF. Because Myer lemons were sweeter, I only used 1/2 C sugar in the filling. These bars came out perfectly tangy. Thank you for sharing your prize winner recipe. I believe my daughter in law will make them again.
