Rolled fondant which is not to be confused with poured fondant, is commonly used to decorate wedding cakes and custom made cake. Fondant has pliable dough-like consistency and taste somewhat like marshmallow. When covering a cake with fondant it is typically iced with buttercream first and then the fondant is rolled out about 1/8 of an inch and draped over the cake. Using this icing makes it possible to create and decorate complex cake structures.
