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
  • 1 pinch salt
  • Zest of ½1 lemon (½1 tablespoon)
  • Optional: 3-4 tablespoons all purpose flour (if worried about filling sinking)

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F (180°C). Lightly grease and flour an 8×8 inch (20×20 cm) square cake pan or line it with parchment paper to prevent sticking.
  2. Make the Shortbread Base: In a medium bowl, beat the softened butter and powdered sugar on medium speed until combined. Add the flour and a pinch of salt, then beat again until a soft dough forms, approximately 1 ½ minutes. Pat this dough evenly into the bottom of the prepared pan. Bake for 18-20 minutes until lightly golden. Remove from oven but leave the oven on. Let the crust cool completely before adding the filling.
  3. Prepare the Lemon Filling: In another medium bowl, beat together the eggs, granulated sugar, baking powder, fresh lemon juice, a pinch of salt, and lemon zest until well combined. If concerned about the filling sinking, incorporate 3-4 tablespoons of all-purpose flour to help stabilize the mixture.
  4. Assemble and Bake: Pour the lemon filling over the cooled shortbread crust evenly. Return the pan to the oven and bake for 20-25 minutes or until the center is set (about 25 minutes is recommended; adjust baking time as needed).
  5. Cool and Serve: Allow the lemon squares to cool in the pan. For easier cutting, chill in the refrigerator for at least 1 hour. Once chilled, cut into squares, remove from the pan, dust with powdered sugar, and serve. Enjoy your delightful lemon squares!

Notes

  • Ensure the crust is cooled before adding the lemon filling to avoid a soggy base.
  • If you want a firmer filling, add 3-4 tablespoons of all-purpose flour to the lemon mixture to prevent sinking.
  • Chilling the lemon squares before cutting helps achieve clean slices.
  • You can adjust the lemon zest amount to your taste preference for more or less citrus aroma.
  • Store leftovers refrigerated in an airtight container for up to 3 days.
