Summer never tasted so good. I highly recommend serving this blueberry crisp hot with ice cream.
Preheat the oven to 350 degrees F (175 degrees C). Coat an 8-inch square baking dish with cooking spray.
Combine blueberries, sugar, and flour in a bowl. Toss gently until berries are coated. Pour into the prepared baking dish.
Mix brown sugar, flour, oats, butter, baking soda, salt, and cinnamon in another bowl with 2 knives or a pastry blender. Sprinkle over the blueberry mixture.
Bake in the preheated oven until golden brown and bubbly, about 30 minutes.
