Ingredients
  

Shortbread Crust

  • 1 cup all-purpose flour
  • 0.5 cup unsalted butter cold and cubed
  • 0.25 cup powdered sugar
  • 1 pinch salt

Lemon Filling

  • 1 cup granulated sugar
  • 2 tbsp all-purpose flour
  • 3 eggs large
  • 1/2 cup fresh lemon juice
  • 1 tbsp lemon zest finely grated

Instructions
 

  • Preheat your oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving a bit of overhang for easy lifting.
  • In a bowl, mix the flour, powdered sugar, and salt. Add in the cold butter and cut it in using a pastry cutter or fingers until it resembles coarse crumbs.
  • Press the crust mixture evenly into the prepared pan and bake for 18–20 minutes until lightly golden around the edges.
  • While the crust is baking, whisk together sugar, flour, eggs, lemon juice, and lemon zest until smooth.
  • Pour the lemon mixture over the hot crust immediately after removing it from the oven.
  • Return to the oven and bake for another 18–20 minutes, until the center is just set and no longer jiggles.
  • Cool at room temperature for 1 hour, then refrigerate for at least 2 hours before slicing.
  • Dust with powdered sugar before serving. Optional: garnish with lemon zest.

Notes

These lemon bars can be made ahead and stored in the fridge for up to 5 days or frozen for up to 3 months. Chill completely before slicing for clean cuts.
