I am making a top dummy layer (8X4)for my daughter's birthday cake. because of lack of time I want to make it a few weeks ahead of time. This has worked in the past for me with small gum paste figures, so I am wondering can i use the gumpaste like fondant to cover the dummy? I'm under the understanding that fondant will not keep this long. the edible layer will not be fondant but regular frosting so no need to match it up.

Thanks---I have so little free time to do this but want a fantastic cake for her first birthday.....any advice is most welcome!!!

Rolled Fondant will absolutely last that long. Dummy cakes covered in fondant are often left on display for years. Gumpaste dries so quickly that it would be difficult to cover a cake with and get a nice finish.

oh really? that would be great..I read somewhere online that it should only be left for a week or two. the party is memorial day weekend and Id like to get started now! will go ahead with fondant, wish me luck!
