How to Make Delicious Lemon Crumb Bars



For the Crust and Crumb Topping:

  • 1 1/2 cups all-purpose flour
  • 1/2 cup granulated sugar
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, cold and cubed
  • 1 large egg

For the Lemon Filling:

  • 2 large lemons (to yield about 1/2 cup lemon juice and 2 teaspoons lemon zest)
  • 1 cup granulated sugar
  • 2 tablespoons all-purpose flour
  • 2 large eggs


  1. Prepare the Crust:
    • Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides to lift out the bars easily after baking.
    • In a large bowl, mix together 1 1/2 cups flour, 1/2 cup sugar, baking powder, and salt. Add the cubed cold butter and use a pastry cutter or your fingers to blend it into the dry ingredients until the mixture resembles coarse crumbs.
    • Stir in the egg to form a crumbly dough.
    • Press about two-thirds of this mixture into the bottom of the prepared pan to form a firm, even layer. Reserve the remaining mixture for the topping.
  2. Bake the Crust:
    • Bake the crust in the preheated oven for 15-20 minutes, or until lightly golden. Remove from the oven and let cool slightly while you prepare the filling.
  3. Make the Lemon Filling:
    • Zest and juice the lemons to get approximately 2 teaspoons of zest and 1/2 cup of juice.
    • In a bowl, whisk together 1 cup sugar, 2 tablespoons flour, lemon zest, lemon juice, and 2 eggs until well combined.
  4. Assemble and Bake:
    • Pour the lemon filling over the pre-baked crust, spreading it evenly.
    • Crumble the remaining dough mixture over the lemon filling to create a crumb topping.
    • Return to the oven and bake for an additional 20-25 minutes, or until the filling is set and the topping is lightly golden.
  5. Cool and Serve:
    • Let the bars cool in the pan on a wire rack. Chill in the refrigerator for at least 2 hours to set before cutting into squares.
    • Lift the bars out of the pan using the parchment paper overhang and cut them into squares.
