Ingredients:

  • 1 cup (225g) unsalted butter, softened
  • 1/2 cup (60g) powdered sugar
  • 2 cups (250g) all-purpose flour
  • 1/4 tsp (1.5g) salt
  • 4 large eggs
  • 2 cups (400g) granulated sugar
  • 1/4 cup (30g) all-purpose flour
  • 2/3 cup (160ml) fresh lemon juice
  • 2 tbsp (12g) fresh lemon zest

Instructions:

  1. Preheat your oven to 350°F (175°C). Line your 9x13 pan with parchment paper, leaving an overhang on the sides.
  2. Cream the softened butter and powdered sugar until smooth. Stir in the flour and salt until a soft dough forms.
  3. Press the dough firmly and evenly into the bottom of the pan.
  4. Bake for 20 minutes or until the edges are just starting to turn a pale, golden brown.
  5. While the crust is baking, whisk together the eggs and granulated sugar in a bowl until combined.
  6. Sift in the flour to prevent lumps, then stir in the lemon juice and zest.
  7. Whisk until the mixture is completely smooth and the lemon oils are fully incorporated.
  8. Pour the lemon filling directly over the hot crust.
  9. Bake for another 20–25 minutes until the edges are set and the center has a slight, jelly-like jiggle.
  10. Remove from the oven and let cool to room temperature before refrigerating for at least 2 hours.
