Instructions
Shortbread Crust
Preheat oven to 350° F. Prepare an 8x8 baking pan with nonstick cooking spray and parchment paper on the bottom and sides of the pan.
In the bowl of a stand mixer or large mixing bowl, combine all-purpose flour, powdered sugar, salt, and cubed unsalted butter. Mix on low speed with an electric hand mixer or stand mixer fitted with a paddle attachment until the mixture becomes crumbly.
Pour the crumbly mixture into the prepared baking pan. Press the crumbs into the bottom of the pan using a flat-bottomed measuring cup to create an even crust.
Bake the shortbread crust for 15 minutes. Remove from the oven and allow to cool while making the filling.
Lemon Filling
Lower the oven temperature to 325° F.
In a large mixing bowl, whisk together granulated sugar, all-purpose flour, lemon zest, lemon juice, and eggs. Whisk until well combined and smooth. The lemon filling will be thin.
Pour the lemon filling on top of the shortbread crust.
Bake the lemon bars for approximately 20-25 minutes until the lemon filling is set and does not jiggle in the center.
Remove from the oven and cool to room temperature. Cover the pan with plastic wrap and chill in the refrigerator for at least 2 hours.
To serve, remove the lemon bars from the pan and cut into squares. Add a dusting of powdered sugar, if desired.
Notes
Lemon bars can be stored in an airtight container in the refrigerator for about 3 days. I recommend dusting with powdered sugar immediately before serving to prevent the sugar from dissolving. Metric conversions are calculated automatically. I cannot guarantee the accuracy of this information.
