Fondant is a type of icing used to decorate cakes, cookies, cupcakes, and pastries (it’s how they make wedding cakes all shiny and smooth!) Fondant can usually be divided into two groups: poured fondant (like the type that can be found in Cadbury Creme Eggs) and rolled fondant. Regular rolled fondant (which contains things like glycerin) is not very tasty, while rolled marshmallow fondant (abbreviated often as MMF) is a bit softer and tastes much better. Fondant can be purchased at cake decorating stores and art supply stores such as Michaels, or made at home. Store bought fondant is expensive and also tastes awful. I mean, really bad.

Despite popular belief, fondant can be easy to make, inexpensive, and delicious. Gone are the days of disgustingly sweet fondant (I have personally banished them – you can thank me by subscribing or sending me gifts… I like chocolate).
