Down East Blueberry Buckle Recipe

Preheat oven to 375 °. In a large bowl, whisk flour, sugar, baking powder and salt. In another bowl, whisk egg, milk and melted butter until blended. Add to flour mixture; stir just until moistened. Fold in blueberries. Transfer to a greased 9-in. square baking pan. For topping, in a small bowl, mix sugar, flour and cinnamon. Using a fork, stir in softened butter until mixture is crumbly. Sprinkle over batter. Bake 30-35 minutes or until a toothpick inserted in center comes out clean (do not overbake). Cool in pan on a wire rack. Serve warm or at room temperature.
