Preheat your oven to 350°F (175°C) and line a baking dish with parchment paper. This makes for easy removal later on!
In a mixing bowl, stir together the melted butter, granulated sugar, and flour until combined. Press this mixture firmly into the bottom of the prepared baking dish to create an even crust.
Bake the crust in the preheated oven for about 20 minutes or until it’s lightly golden. While it’s baking, prepare the lemon filling by whisking together eggs, lemon juice, zest, and powdered sugar in a separate bowl.
Once the crust is ready, pour the lemon mixture over the baked crust and return it to the oven for another 10-15 minutes until just set but still soft.
Allow the bars to cool completely before slicing them into squares. Dust with powdered sugar before serving for a lovely finish!
Notes
Enjoy these bars chilled or at room temperature. They make for a refreshing dessert any time of year!
