¼ Cup butter or margarine, softened
¾ Cup Sugar
2 Eggs
1 Tsp. vanilla extract
2-1/4 Cups all-purpose flour, divided
2 Tsp. baking powder
½ Tsp. salt
½ Cup buttermilk
2 ½ Cups fresh or frozen blueberries
Topping:
¼ Cup all-purpose flour
¼ Cup packed brown sugar
¼ Cup sugar
½ Tsp. ground cinnamon
¼ Cup cold butter or margarine
In a mixing bowl, cream butter and sugar. Add eggs and vanilla; mix well. Combine 2 Cups of flour, baking powder and salt; add to creamed mixture alternately with buttermilk. Mix well. Toss berries in remaining flour; fold into batter (discard any flour that doesn’t stick to berries). Spread batter in a greased 9 inch square baking pan.
For topping, combine flour, sugars and cinnamon; cut in butter until the mixture resembles coarse crumbs. Sprinkle over batter. Bake at 375 degrees for 25-30 minutes or until a toothpick inserted near center comes out clean. Cool on a wire rack.
