5-Ingredient Lemon Crumb Bars
These easy Lemon Crumb Bars have a buttery crumb crust topped with a tangy lemon filling and more crumb topping. Perfect for a refreshing dessert with minimal ingredients.
Ingredients
- 1 cup unsalted butter softened
- 2 cups all-purpose flour
- 0.5 cup granulated sugar
- 1 large egg
- 1 can sweetened condensed milk 14 ounces
- 0.5 cup fresh lemon juice from about 2-3 lemons
- 1 tablespoon lemon zest
Instructions
- Preheat oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving an overhang on two sides.
- In a medium bowl, combine softened butter, flour, and sugar. Use a pastry blender or your fingers to form coarse crumbs.
- Measure out 1 ½ cups of the crumb mixture and press evenly into the bottom of the prepared pan.
- Bake the crust for 15 minutes, until edges are lightly golden.
- While the crust bakes, whisk together sweetened condensed milk, egg, lemon juice, and lemon zest until smooth.
- Pour the lemon filling over the warm crust. Sprinkle the remaining crumb mixture evenly on top.
- Bake for 25-30 minutes, until the filling is set and topping is golden brown.
- Cool completely on a wire rack for at least 1 hour. Chill an additional 30 minutes for best results.
- Use the parchment paper handles to lift the bars out of the pan. Slice into 16 squares and serve.
Notes
Use fresh lemon juice for the best flavor. Do not overmix the crumb mixture. Allow bars to cool completely for clean cuts. Dust with powdered sugar if desired.
