Bake for 25 to 30 minutes or when a toothpick inserted in the center of the cake comes out clean. Transfer cakes to a rack and cool for 5 minutes. Run a knife around the sides of the cake, unmold them and peel off the paper liner. Invert and cool to room temperature, right side up (These cooled cakes may be wrapped airtight and stored at room temperature overnight, or frozen up to two months).
