Ingredients

Scale

Shortbread Base

  • ½ cup butter (softened)
  • ¼ cup powdered sugar
  • 1 cup flour
  • 1 pinch salt

Lemon Filling

  • 2 large eggs
  • 1 cup granulated sugar
  • ½ teaspoon baking powder
  • 3 tablespoons lemon juice (freshly squeezed)
  • 1 pinch salt
  • Zest of ½1 lemon (½1 tablespoon)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (180°C). Lightly grease and flour an 8×8 inch (20×20 cm) square baking pan or line it with parchment paper to prevent sticking.
  2. Prepare Shortbread Base: In a medium bowl, beat the softened butter and powdered sugar on medium speed until combined. Add the flour and pinch of salt, then beat until a soft dough forms, about 1½ minutes. Press the dough evenly into the prepared pan.
  3. Bake Base: Bake the shortbread base in the preheated oven for 18-20 minutes until lightly golden. Remove from the oven and allow the crust to cool completely while leaving the oven on for the next step.
  4. Mix Lemon Filling: In another medium bowl, beat together the eggs, granulated sugar, baking powder, lemon juice, salt, and lemon zest until fully combined. Optionally, add 3-4 tablespoons of all-purpose flour if concerned about the filling sinking.
  5. Assemble and Bake: Pour the lemon filling over the cooled shortbread base. Return the pan to the oven and bake for 20-25 minutes, or until the center is set. Baking time may vary slightly.
  6. Cool and Serve: Remove from the oven and cool completely in the pan. For best results, chill in the refrigerator for 1 hour to make cutting easier. Cut into 16 squares, dust with powdered sugar, and serve.

Notes

  • Ensure the shortbread base is fully cooled before adding the filling to prevent it from melting or mixing unevenly.
  • If you notice the filling sinking during baking, gently folding in a few tablespoons of flour can help stabilize it.
  • You can adjust the lemon zest amount to your taste for a stronger or milder lemon flavor.
  • Chilling the lemon squares after baking helps them set well and makes slicing easier and cleaner.
  • For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend suitable for baking.
