Buttery Blueberry Oat Crumble Bars

Instructions

1. 1

   Preheat the oven to 375°F. In a large bowl, combine the flour, oats, 1 cup of sugar, and baking soda. Cut in the cold butter until the mixture resembles coarse crumbs. Reserve 2 cups of the crumb mixture for the topping. Press the remaining crumb mixture into a greased 13x9-inch baking pan.

2. 2

   In a large saucepan, combine the blueberries, cornstarch, lemon juice, and the remaining 1/2 cup of sugar. Bring the mixture to a boil and cook for 2 minutes, stirring constantly, until thickened.

3. 3

   Spread the blueberry mixture evenly over the prepared crust. Sprinkle the reserved crumb mixture over the top. Bake for 30 minutes or until the topping is lightly browned. Allow the bars to cool completely on a wire rack before cutting into 12 squares.
