Blueberry Crumble Bars

Ingredients

• 1 1/2 cups all-purpose flour
• 1 1/2 cups quick cooking oats
• 1 1/2 cups white sugar, divided
• 1/2 teaspoon ground cinnamon
• 1/2 teaspoon baking soda
• 3/4 cup cold butter
• 2 cups blueberries
• 2 tablespoons cornstarch
• 2 tablespoons lemon juice

Directions

Preheat oven to 375 degrees F (190 degrees C). Grease a 9×13-inch baking dish.

Combine flour, oats, 1 cup sugar, cinnamon, and baking soda in a large bowl. Cut butter into flour mixture until it resembles coarse crumbs. Reserve about 2 cups flour-butter mixture. Press remaining mixture into the prepared baking dish to form a crust.

Bring blueberries, remaining 1/2 cup sugar, cornstarch, and lemon juice to a boil in a saucepan, stirring constantly, until mixture is thickened, about 2 minutes. Spread blueberry mixture over crust and sprinkle with reserved oat mixture.

Bake in the preheated oven until topping is just browned, about 25 minutes. Cool before cutting and serving.
