Description
Lemon Blueberry Crumb Bars are sweet, tangy dessert bars with a buttery crumb crust, a bright lemon-blueberry filling, and a golden, crumbly topping. Perfect for warm-weather gatherings or anytime you crave a fruity treat.
Ingredients
- For the crumb base and topping:
- 1 1/2 cups all-purpose flour
- 1/2 cup granulated sugar
- 1/4 cup brown sugar
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, cold and cubed
- 1 large egg
- 1 teaspoon vanilla extract
- For the lemon blueberry filling:
- 2 cups fresh or frozen blueberries
- 1/3 cup granulated sugar
- 2 teaspoons cornstarch (3 tsp if using frozen berries)
- 1 tablespoon lemon zest
- 2 tablespoons lemon juice
Instructions
- Preheat oven to 350°F (175°C). Grease or line an 8×8 or 9×9-inch baking pan with parchment paper.
- In a large bowl, combine flour, granulated sugar, brown sugar, baking powder, and salt.
- Cut in the cold cubed butter using a pastry cutter or fork until the mixture resembles coarse crumbs.
- Mix in the egg and vanilla extract until a crumbly dough forms.
- Press about two-thirds of the crumb mixture into the bottom of the prepared pan to form an even crust.
- In another bowl, toss blueberries with sugar, cornstarch, lemon zest, and lemon juice until coated.
- Spread the blueberry mixture evenly over the crust.
- Crumble the remaining dough over the top of the blueberry layer.
- Bake for 40–45 minutes, or until the top is golden and the filling is bubbling.
- Let cool completely in the pan. For clean cuts, chill in the refrigerator for 1 hour before slicing into bars.
Notes
- Use cold butter for a crisp crumb texture.
- Fresh lemon zest and juice provide the best flavor.
- For a cleaner slice, chill the bars before cutting.
- Frozen blueberries can be used straight from the freezer—just add extra cornstarch.
- Double the recipe for a crowd and bake in a 9×13-inch pan.
