Blueberry Boy Bait (for bars)
2 cups flour
1½ cups sugar
2/3 cup cold butter
2 tsp. baking powder
1 tsp. salt
1 cup milk
2 eggs, separated
2 cups blueberries
1 teaspoon cinnamon, optional
Preheat oven to 350 degrees. In a medium bowl mix flour, sugar and cut in cold butter, until crumbly-like pastry dough. Set aside ¾ cup of this mixture for topping, adding cinnamon if desired.
To remainder of flour mixture, add baking powder, salt, milk and egg yolks. Mix well.
Beat egg whites until firm; fold into batter and pour into a buttered/floured 9x13 inch baking dish. Scatter blueberries evenly over the batter and sprinkle with the remainder of the reserved flour/sugar/butter mixture to make a crumb topping.
Bake at 350 degrees for 40-50 minutes, until cake springs back to the touch.
Serve warm, or cool and cut into bars.
