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.

    They taste alright, but look pretty unattractive. Additional eggs would have helped custard set up better without having to bake as long, also no instruction in recipe to watch or turn down oven if using a glass pan. Won’t be using this recipe again.

    1. Video shows 2 eggs ! Recipe calls for 4, which is it? Wanna make but not sure on how many eggs!🤷‍♀️

  2. 5 stars

  4. 3 stars
    I followed recipe to the t. Loved the crust but filling was tasteless. I am wondering if my lemons were too old? Disappointed.

  5. These are the best. I’m rather known for my lemon bars but, I’m changing my recipe to this one. Love them
