Description
Simple recipe for sweet and tart blueberry crumble bars with a buttery crust and topping.
Ingredients
Scale
- 1 1/2 cups all-purpose flour
- 1/2 cup rolled oats
- 1/2 cup packed brown sugar
- 1/4 teaspoon salt
- 1/2 cup (1 stick) cold unsalted butter, cut into pieces
- 1 1/2 cups fresh or frozen blueberries
- 1/4 cup granulated sugar
- 1 tablespoon cornstarch
- 1 teaspoon lemon juice
Instructions
- Preheat your oven to 375 degrees F (190 degrees C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
- In a medium bowl, combine the flour, oats, brown sugar, and salt for the crust/crumble.
- Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
- Press two-thirds of the crumb mixture evenly into the bottom of the prepared baking pan.
- In a separate bowl, gently toss the blueberries with the granulated sugar, cornstarch, and lemon juice.
- Spread the blueberry mixture evenly over the crust layer.
- Sprinkle the remaining one-third of the crumb mixture over the blueberries.
- Bake for 35 to 40 minutes, or until the topping is golden brown and the filling is bubbly.
- Let the bars cool completely in the pan on a wire rack before lifting them out using the parchment overhang and cutting into squares.
Notes
- If using frozen blueberries, do not thaw them before mixing with the sugar and cornstarch.
- For a richer flavor, substitute half of the all-purpose flour with whole wheat flour.
- You can store leftover bars tightly covered at room temperature for up to three days.
