Place a thick, clean towel in the kitchen sink and pour a kettle of boiling hot water over the towel to heat it (don’t plug the sink to retain the water, allow it to drain out). Set the cake (still inside the pan) on the hot towel and leave it for a minute or two, the cake should turn out easily.

Turn the cake over on a sheet of wax paper or a cooling rack. Place a clean, thin cotton towel on top of the cake pan and using a hot steam iron, heat the bottom of the pan for a few minutes. The pan should lift off cleanly.

Cool the cakes in the pans completely before trying to remove them. Don’t cool on top of the stove where there’s heat, they’re best cooled on a rack on top of the counter. Gently insert a knife between the outside of the cake and the inside of the pan. Run it along the pan to loosen things up before turning over.
