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.

Do you have to leave them to rest a bit before you serve?

I’m making this today for when my parents come over 🙂 Excited!

I got several good comments from these. For me, though, they were way too sweet! Could have used half the sugar, and would have tasted more of the lemon. Next time I will try that.

I used two small lemons to zest. Very lemony. Crust is nice and short.
Winner!

Made these for Christmas and everyone agrees – they were the best lemon bars ever!!! Thank you! Can’t wait to make them again, although it is dangerous to have them in the house!

This is the same recipe my mother-in-law used to make and one of the few I’ve seen that uses baking powder in the filling. Instead of sprinkling powdered sugar over the bars, she’d make a glaze…1/2 cup powdered sugar, 1 TBSP lemon juice, 1 tsp. Lemon zest and 1 TBSP melted butter. Spread it on the filling after it’s cooled. Try it. You’ll like it!
