Description

These Lemon Crumb Bars combine a tangy, bright lemon filling with a buttery, golden crumb topping, creating a perfect balance of sweet and tart in every bite. With a crisp shortbread base and a zesty lemon layer, these bars are an ideal dessert for any occasion, offering a delightful texture contrast and refreshing flavor.


Ingredients

For the Crust and Crumb Topping

  • 1 cup unsalted butter, softened
  • 1/2 cup granulated sugar
  • 2 cups all-purpose flour
  • 1/4 teaspoon salt

For the Lemon Filling

  • 4 large eggs
  • 1 1/2 cups granulated sugar
  • 1/4 cup all-purpose flour
  • 1/2 cup fresh lemon juice (about 2–3 lemons)
  • 1 tablespoon lemon zest

Instructions

  1. Prepare the Crust: Preheat your oven to 350°F (175°C). In a large mixing bowl, cream together the softened butter and sugar until light and fluffy. Gradually mix in the flour and salt until the dough resembles coarse crumbs. Press about two-thirds of this mixture evenly into the bottom of a greased 9×13 inch baking pan to form the crust.
  2. Bake the Crust: Bake the crust in the preheated oven for 15-18 minutes, or until it is lightly golden. Remove it from the oven and set aside while you prepare the lemon filling.
  3. Make the Lemon Filling: In a separate bowl, whisk together the eggs, sugar, and flour until smooth. Stir in the fresh lemon juice and lemon zest to infuse the filling with bright, citrusy flavor.
  4. Assemble and Bake: Pour the lemon filling evenly over the warm crust. Crumble the remaining one-third of the crumb mixture on top of the lemon layer to create a crunchy topping. Return the pan to the oven and bake for an additional 20-25 minutes, or until the filling is set and the crumb topping is golden brown.
  5. Cool and Serve: Remove the bars from the oven and allow them to cool completely in the pan on a wire rack. Once cooled, cut into squares and serve. For the best flavor, refrigerate for at least an hour before serving to let the filling fully set.

Notes

  • Use fresh lemons for the best flavor; bottled lemon juice may alter the taste significantly.
  • Ensure the crust is baked lightly before adding the filling to prevent sogginess.
  • For a less sweet version, reduce the sugar in the filling by 1/4 cup.
  • Store lemon crumb bars in an airtight container in the refrigerator for up to 4 days.
  • The bars can be dusted with powdered sugar before serving for added sweetness and presentation.
