This recipe is simple and if you follow the directions, it never fails. It is a family favorite and I highly recommend it. I made no changes to the recipe, however, I did put a pan of water on the rack below it. When the cake is done I turn the stove off and open the door of the oven, letting the cake cool slowly at first. After about five minutes I remove it from the oven totally and gently loosen the sides with a knife. I never have problems with the cake cracking on the surface.
