Preheat oven to 450 degrees F. Combine all ingredients except the berries and mix well. Fold in berries. Pour into a greased and floured tube/bundt pan. Sprinkle a layer of sugar on top. Bake at 450 degrees F for 10 minutes, then reduce heat to 350 degrees F and bake for another 40 to 50 minutes. Instead of blueberries, try substituting 2 cups fresh cranberries and 1/2 cup walnuts.
