Recipe Information
Ingredients
- 2.5 cups all-purpose flour
- 1 cup granulated sugar
- 0.5 cup brown sugar, packed
- 1 cup unsalted butter, melted
- 1 teaspoon baking powder
- 0.25 teaspoon salt
- 1 teaspoon vanilla extract
- 3 cups blueberries, fresh or frozen
- 2 tablespoons lemon juice
- 1 teaspoon lemon zest
- 1.5 tablespoons cornstarch
Instructions
Preheat your oven to 375°F (190°C). Grease and line a 9x13-inch baking pan with parchment paper for easy removal.
In a large mixing bowl, combine the all-purpose flour, granulated sugar, brown sugar, baking powder, and salt.
Pour in the melted butter and vanilla extract. Mix with a fork until the mixture resembles coarse crumbs and can hold together when pressed.
Take half of the crumb mixture and firmly press it into the bottom of the prepared baking pan to form the crust. Set aside the remaining crumb mixture for the topping.
In another bowl, mix the blueberries, lemon juice, lemon zest, granulated sugar (if desired for sweetness), and cornstarch until the blueberries are evenly coated.
Spread the blueberry mixture evenly over the crust in the pan.
Sprinkle the remaining crumb mixture over the blueberries, ensuring the topping is evenly distributed.
Bake in the preheated oven for 40-45 minutes, or until the topping is golden brown and the blueberry filling is bubbling.
Remove from the oven and allow the bars to cool completely in the pan before cutting into squares for serving.
