Shortbread Crust:

  • 1 cup unsalted butter melted
  • 1/2 cup caster sugar
  • 1 teaspoon pure vanilla extract
  • 1/2 teaspoon salt
  • 1 tablespoon lemon zest
  • 2 1/4 cups all-purpose flour

Lemon Filling:

  • 2 cups caster sugar
  • 8 tablespoons all-purpose flour
  • 8 large eggs
  • 1 teaspoon vanilla extract
  • 1 ¼ cup lemon juice about 4-5 lemons


  • Confectioners’ sugar
  • Lemon slices


  • Preheat the oven to 325°F.
  • Line the bottom and sides of a 9×13 baking pan with parchment paper, leaving an overhang on the sides, this will help to lift the bars out of the pan. Set aside.


  • In a medium bowl combine the melted butter with sugar, vanilla extract, and salt.
  • Add the flour and stir to fully combine. The dough will be thick.
  • Press the dough firmly into the prepared pan, in an even layer.
  • Bake for 20-23 minutes or until the edges are just lightly browned.
  • Remove from the oven and use a fork to poke holes all over the warm crust, but not all the way through the crust.


  • Sift the sugar and flour together in a large bowl.
  • Add the eggs, vanilla, and lemon juice and whisk until fully combined.
  • Pour lemon filling over the warm crust and bake for 20-25 minutes, or until the center is relatively set and no longer jiggles.
  • Remove from the oven and cool completely on a wire rack. Place in the refrigerator for 2 more hours until fully chilled.
  • Once cooled and ready to serve, lift the parchment paper out of the pan using the overhang on the sides.
  • Dust with confectioners’ sugar and cut into squares.
  • Optionally garnish with lemon slices before serving.
