ROLLED FONDANT

Rolled fondant or fondant icing, which is not the same material as poured fondant, is commonly used to decorate wedding cakes. It includes gelatin (or agar in vegetarian recipes) and food-grade glycerine, which keep the sugar pliable and creates a dough-like consistency. It can also be made using powdered sugar and melted marshmallows. Rolled fondant is rolled out like a pie crust and used to cover the cake. This gives the cakes a smooth appearance. (Wikipedia)
