  • 1/2 cup unsalted butter, melted
  • 1 2/3 cup all purpose flour
  • 1/3 cup powdered sugar
  • 1/4 tsp salt
  • 2 tsp lemon zest
  • 4 eggs
  • 1 1/2 cups sugar
  • 1 Tbsp lemon zest
  • 1/2 cup lemon juice, freshly squeezed
  • 1/2 cup flour
  • Powdered sugar for dusting, optional
  1. Preheat oven to 350 degrees. Grease a 9x9 baking pan, or line it with parchment paper (or non stick foil).

Shortbread Crust
  1. Mix all purpose flour, powdered sugar, salt, and lemon zest together.

  2. Add in melted butter. Mix until the shortbread dough is well combined.

  3. Using a rubber spatula, press the dough into the baking dish in an even layer.

  4. Bake the crust for 12-15 minutes, or until just barely turning golden brown. (Allow to cool at least 10 minutes before adding the lemon filling.)

Lemon Filling
  1. In a medium bowl, whisk eggs, lemon juice, and lemon zest together.

  2. Next, add in granulated sugar and all purpose flour and whisk until smooth and combined.

  3. Pour the filling over the cooled crust and bake for 22-25 minutes, or until the filling is set and no longer jiggles when gently shaken.

  4. Allow to cool to room temperature, then refrigerate until ready to eat. (Leftovers should be stored in the fridge too.)

  5. Cut into squares. Dust with powdered sugar, if desired.

  6. Enjoy!
