6. Pour shortcake batter evenly into prepared cake pans. Bake at 350 degrees for 12-15 minutes if using two 6 inch cake pans or 20-25 minutes if using one 8 inch cake pan. Remove from oven. Let cool for several minutes until you can handle the sides of the pan before loosening the cake from the sides of the pan. Flip cake over onto a wire rack to cool completely. If making one large cake, slice cake in half horizontally once it has cooled.
