I have a wedding next Saturday and the bottom tier is going to be a dummy cake layer. We are doing buttercream on it. How do I prepare the styrofoam layer? Do I need to saran wrap and then just frost like normal?

Thanks!

If you are using the standard dummy cake, you don't need to wrap it. If you want to reuse the dummy- Once the icing is dry, it will just pull off and you can wipe off any excess.

If you are using regular open styrofoam, you may want to apply a crumb coat to seal the surface, chill or set the crumb coat, then ice it.

using plastic wrap can make wrinkles that can be hard to hide.

Agree with JoAnn ... I never wrap or prep dummies. BC icing goes straight on them.
