I have a request to make a big cake in the shape of a friend's pill-shape buoy. The bottom half of the cake will be styrofoam with a cake board to separate it from the actual edible cake. Then the entire cake will be iced and covered with fondant. I was wondering do I need to wrap the styrofoam or do anything to it before I ice it??? I wasn't sure if I needed to do anything more to keep bits of it from getting onto the cake.

Thank you so much. This is for this Saturday

I don't wrap it. If you use "true" cake dummies, there's nothing from the styro to get into the cake. It's a nice solid styro. If you're planning on using that crumbly green stuff (which I wouldnt' recommend), that's a different story.

If you are using sytrofoam that you have to cut into, it will have bits of stuff and I would recommend covering it really good. You don't want anything to get into the cake .....but if it is a cake dummy which it did not sound like thats what you meant, maybe I am wrong.....but as Deb said, it should not be loose stuff on it.
