Blueberry Crumble Bars

Directions

1. 1
   Preheat oven to 375°F. Lightly spray a 9x13-inch baking pan with cooking spray; set aside.
2. 2
   In a medium bowl, combine 1/2 cup granulated sugar, brown sugar, baking powder and flour. Using a pastry cutter or two forks (I used my hands), cut in butter. Add egg and lemon extract and mix until well combined and resembles coarse crumbs.
3. 3
   Take half of the mixture and press into the bottom of the prepared pan.
4. 4
   In a separate bowl, combine blueberries, remaining 1/2 cup granulated sugar and cornstarch. Stir gently.
5. 5
   Add blueberry mixture evenly over the crust. Crumble remaining dough over the top of the blueberries.
6. 6
   Bake for 45 minutes or until the top is lightly browned. Remove from oven and allow to cool completely before cutting.
