Ingredients
FOR THE CRUST
  • 1 cup flour
  • 1/4 tsp salt
  • 1/4 cup confectioner's sugar
  • 8 tblsp unsalted butter, room temperature
FOR THE TOPPING
  • 4 large eggs
  • 1 large egg yolk
  • 1 cup plus 2 tablespoons of granulated sugar
  • 3 tbsp confectioner's sugar
  • 1/4 cup all-purpose flour
  • 1/8 tsp salt
  • 2/3 cup lemon juice
  • 1 tbsp confectioner's sugar, for dusting
Instructions
  1. Preheat the oven to 350°F.

  2. To make the crust: Whisk together the flour, salt, and confectioners' sugar. Add to a food processor, add butter and pulse until mixture is light and crumbly.

  3. Press the crust firmly into a parchment lined 8" square pan. If the mixture begins to stick to your hands, chill in the freezer for 5 to 10 minutes, then continue to press into the pan. It's important that the crust is firmly anchored to the pan so no filling seeps underneath.

  4. Bake the crust for 30 to 35 minutes, or until it's golden brown. Remove it from the oven, and reduce the oven temperature to 325°F.

FOR THE TOPPING
  1. While the crust is baking, make the topping: Combine the whole eggs, egg yolk, and sugars and whisk until smooth. Add the flour and salt, then the lemon juice, and whisk until thoroughly combined.

  2. Let the filling sit for 15 minutes or so, until the bubbles (mostly) disappear.

    While the baked crust is still hot, pour the topping over it. Return the bars to the oven and bake until they appear set and relatively dry on top, about 30 minutes.

  3. Remove the bars from the oven, and cool them on a rack. Let them cool completely before slicing. Just before serving, sprinkle the top of the bars with confectioners' sugar.

  4. Store any leftovers in the refrigerator for up to several (3 to 4) days.
