Ingredients

For the Crust and Topping:

  • 1/2 cup granulated sugar
  • 1/4 teaspoon salt
  • 1 cup unsalted butter, cold and cubed

For the Lemon Filling:

  • 2 large eggs (room temperature)
  • 1 cup granulated sugar
  • 1/4 cup fresh lemon juice (about 2–3 lemons)
  • 2 tablespoons lemon zest (from about 2–3 lemons)
  • 2 tablespoons all-purpose flour
  • 1/4 teaspoon baking powder

Step-by-Step Instructions

Step 1: Preheat & Prep

  1. Preheat your oven to 350°F (175°C).
  2. Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal. Lightly grease the paper.

Step 2: Make the Crust and Topping

  1. In a large bowl, combine flour, sugar, and salt.
  2. Add cold, cubed butter and use a pastry cutter, fork, or hands to mix until the mixture resembles coarse crumbs.
  3. Reserve 1 cup of this crumb mixture for the topping.
  4. Press the remaining mixture firmly into the bottom of the prepared pan to form the crust.

Step 3: Bake the Crust

  1. Bake for 15 minutes, or until lightly golden around the edges.
  2. Remove from the oven and allow to cool slightly while you prepare the filling.

Step 4: Make the Lemon Filling

  1. In a medium bowl, whisk together eggs, sugar, lemon juice, lemon zest, flour, and baking powder until smooth.

Step 5: Assemble the Bars

  1. Pour the lemon filling evenly over the warm crust.
  2. Sprinkle the reserved crumb mixture evenly over the top, pressing lightly to help it adhere.

Step 6: Bake Again

  1. Bake for 25–30 minutes, or until the topping is golden brown and the filling is set.
  2. Let the bars cool completely in the pan on a wire rack.
  3. For cleaner slices, chill in the refrigerator for 1–2 hours before cutting.

Step 7: Serve

  1. Lift the bars out of the pan using the parchment paper overhang.
  2. Cut into squares or rectangles and serve at room temperature or chilled.

Tips for Success
