Ingredients

For the shortbread crust:

  • Vegetable oil cooking spray, as needed
  • ½ cup granulated sugar
  • ¼ teaspoon table salt
  • 1 cup all-purpose flour
  • 8 tablespoons unsalted butter, melted

For the lemon custard:

  • 4 eggs
  • 1 cup granulated sugar
  • 2/3 cup freshly squeezed lemon juice, from about 6 lemons
  • ¼ cup all-purpose flour
  • ½ teaspoon baking powder
  • ½ teaspoon table salt
  • Confectionary sugar, as needed, for dusting
  • 1 teaspoon crushed dried lavender
  • Lemon slices, cut into quarters

Instructions

For the shortbread crust:

  • Preheat oven to 350ºF (180ºC). Spray a 9x9-inch square baking pan with vegetable oil cooking spray.
  • Add the sugar, salt and flour to the bowl of a food processor and pulse until combined. Add butter and continue to pulse until large crumbs form.
  • Evenly press into the bottom of the baking pan and bake until the crust is lightly browned, about 25 minutes.

For the lemon custard:

  • Reduce the heat to 325ºF (170ºC). In the bowl of a stand mixer fitted with the whisk attachment, beat the eggs on medium until they become thick but not frothy.
  • Beat in the granulated sugar, lemon juice, flour, baking powder and salt. Pour the mixture over the crust and evenly spread.
  • Bake until the custard has set, about 20 minutes.
  • Remove from the oven and let cool completely. Once cool, sift the powdered sugar and cut into squares. Garnish with the lavender and lemon slices.
