Bake at 450° for 15-20 minutes or until golden. Remove from pan; cool on wire rack.
Just before serving, split cake in two. butter bottom layer; spoon half of the berries over butter. Replace second layer and spoon remaining berries on top. Cut into individual servings; top each with whipped cream.
