2.When i bake i normally put my cakes in the frig over night to let it sit BUT i read a forum resently that someone said to wrap it in suran wrap and put it in the mircowave over night it makes it more moist.. I did that and my cake was so soft it fell apart when i was take off the suran wrap. does anyone know why?
