Equipment

  • 8x8 baking pan lined with parchment paper
  • Stand mixer fitted with a paddle attachment or electric hand mixer

Ingredients 

Shortbread Crust

  • 1 cup all-purpose flour
  • ¼ cup powdered sugar
  • ¼ tsp salt
  • ½ cup unsalted butter room temperature and cubed

Lemon Filling

  • cups granulated sugar
  • 3 tbsp all-purpose flour
  • 1 tbsp lemon zest
  • ½ cup lemon juice freshly squeezed
  • 3 eggs room temperature

Additional Ingredients

  • ¼ cup powdered sugar for dusting

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.
