Get all the flavor of blueberry crisp in a dessert bar. These blueberry crumble bars have a buttery oat crumble and juicy berry filling.
Ingredients
Crust and Topping
- 1 ½ cups (187 g) all purpose flour
- 1 ½ cups (150 g) rolled oats
- ⅓ cup (66 g) packed light brown sugar
- ⅓ cup (66 g) granulated sugar
- ¼ teaspoon baking powder
- ¼ teaspoon salt
- ¾ cup (12 Tablespoons or 170 g) unsalted butter, softened, but still cool, cut into 1/2-inch pieces
- 1 teaspoon pure vanilla extract
Blueberry Filling
- 2 cups (538 g) fresh blueberries
- ¼ cup (50 g) granulated sugar
- 1 Tablespoon (9 g) cornstarch
- 1 ½ Tablespoon (22 ml) lemon juice
Instructions
- Preheat oven to 350℉. Line a 8×8 baking dish with parchment paper and set aside.
- In the bowl of a stand mixer (or using a hand mixer), combine flour, oats, brown sugar, granulated sugar, baking powder and salt. Mix for 30 seconds until thoroughly combined. With the mixer on low, add the butter and vanilla extract. Mix until the mixture resembles coarse sand (about 2 minutes).
- Transfer half the mixture to prepared pan. Use your hands or the back of a measuring cup to press mixture evenly into the bottom to form the crust. Bake crust for 20 minutes or until golden (keep the oven on).
- While the crust bakes, make the blueberry filling. Bring blueberries, sugar, cornstarch, and lemon juice to a boil in a saucepan, stirring constantly, until mixture is thickened, about 2 minutes. Remove from heat. Cool slightly.
- Spread berry mixture over baked crust. Sprinkle remaining oat mixture evenly over the fruit layer.
- Bake bars for 30 to 35 minutes or until the blueberries bubble and the top is golden brown. Allow bars to cool completely before removing from pan and cutting into 16 squares.
Notes
Frozen blueberries also work. Defrost them completely and discard any juices. Cook the filling and, if necessary, add another tablespoon of cornstarch to thicken the mixture.
Store bars in an airtight container at room temperature for 3 days or in the refrigerator for 5 days.
Freeze for up to 3 months. Wrap cooled bars in plastic wrap and place in a freezer bag or airtight container. Defrost in the refrigerator before bringing to room temperature.
