I'm looking for a fake icing to use on dummy cakes. I thought about using joint compound found at The Home Depot. Can anyone suggest something. I really don't want to spend a lot of money.

Thanks

I usually just use shortening under fondant, or royal icing to cover my cake dummies. Fondant is easier to remove. Royal icing dries as hard as a brick.

Edited to add: There is a picture in my photos (purple and white) I just did covered in fondant with shortening under it .

I took a class on piping not too long ago and we used cake dummies we covered the cake dummy in fondant we used a little water to make it stick and piped with royal icing. Hope this helps,

Ps I used mmf so it's super cheap

I just finished a dummy cake and just sprayed the styrofoam with water to get the fondant to stick. It worked great!

For a bc look I use PermaIce. For fake fondan I use Wilton Fondant. LOL

For BC, I just use my regular recipe but I leave out the dream whip and the flavoring.
