Ingredients

Crust

  • 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

Filling

  • 4 eggs
  • 1 1/2 cups sugar
  • 1 Tbsp lemon zest
  • 1/2 cup lemon juice, freshly squeezed
  • 1/2 cup flour

Topping

  • Powdered sugar for dusting, optional

Instructions

  • Preheat oven to 350 degrees. Grease a 9x9 baking pan, or line it with parchment paper (or non stick foil).

Shortbread Crust

  • Mix all purpose flour, powdered sugar, salt, and lemon zest together.
  • Add in melted butter. Mix until the shortbread dough is well combined.
  • Using a rubber spatula, press the dough into the baking dish in an even layer.
  • 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

  • In a medium bowl, whisk eggs, lemon juice, and lemon zest together.
  • Next, add in granulated sugar and all purpose flour and whisk until smooth and combined.
  • 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.
  • Allow to cool to room temperature, then refrigerate until ready to eat. (Leftovers should be stored in the fridge too.)
  • Cut into squares. Dust with powdered sugar, if desired.
  • Enjoy!
