Recipe Information
Ingredients
- 2.5 cups all-purpose flour
- 1 cup granulated sugar
- 1 cup unsalted butter, cold and cubed
- 1 teaspoon baking powder
- 0.25 teaspoons salt
- 1 large egg
- 3 cups fresh blueberries
- 2 tablespoons lemon juice
- 2 tablespoons cornstarch
- 0.5 cup brown sugar
Instructions
Preheat your oven to 375°F (190°C). Grease and line a 9x13-inch baking dish with parchment paper, leaving a slight overhang for easy removal of the bars.
In a large mixing bowl, whisk together the flour, granulated sugar, baking powder, and salt.
Add the cold cubed butter to the dry ingredients and use a pastry cutter or your hands to blend until the mixture resembles coarse crumbs.
Add the egg to the mixture and combine until it forms a crumbly dough. Reserve about 1 1/2 cups of the dough for the topping and press the remaining dough evenly into the prepared baking dish to form the base.
In a separate bowl, toss the blueberries with lemon juice, brown sugar, and cornstarch until evenly coated.
Spread the blueberry mixture evenly over the dough base in the baking dish.
Sprinkle the reserved crumbly dough evenly over the blueberry layer to form a crumb topping.
Bake in the preheated oven for 35-40 minutes, or until the top is golden and the blueberry filling is bubbling.
Allow the bars to cool completely in the pan before using the parchment overhang to lift them out. Cut into 12 squares and serve.
Store any leftovers in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days.
