**Frost Your Cake First**. Before you add your fondant, you should have a smooth layer of buttercream on your cake. This makes for a great base for your fondant.**Choose the Right Color Base**. If using white fondant, use traditional buttercream. If using black fondant, use chocolate buttercream.**Grease the Surface You’re Working On**.

The best options to use are confectioners’ sugar or shortening.**Turn Fondant Often**. Before you roll and you’re working your fondant, turn it over often to ensure it doesn’t stick and keep it moving.**Grease Hands**.
