1/4 cup butter (half a stick) plus 1 tablespoon
1/2 cup sugar plus 1 tablespoon
1 cup flour plus 2 teaspoons
2 teaspoons baking powder
1/2 teaspoon salt
1 teaspoon cinnamon
1/2 cup milk
2 cups frozen blueberries
Preheat the oven to 350 degrees Fahrenheit.
Butter a baking pan, either round like a quiche pan or any casserole dish would work. Use a paper towel to smear 1 tablespoon of softened butter over the entire inside of the pan. Or spray with non-stick cooking spray.
Melt 1/4 cup of butter in a microwave-safe bowl, about 20-30 seconds.
In a large mixing bowl, combine melted butter with 1/2 cup sugar, 1 cup flour, 2 teaspoons baking powder, 1/2 teaspoon salt, 1 teaspoon cinnamon and 1/2 cup milk. Whisk until smooth.
Pour the batter into your buttered pan.
Open the bag of blueberries. Sprinkle the remaining 2 teaspoons of flour inside and shake or gently massage with your hands. Pour the floured blueberries on top of the batter. Sprinkle with the remaining sugar.
Bake for about 45 minutes until the edges are golden, the center is set, and the fruit is bubbly.
Serve with vanilla ice cream or whipped cream.
