I am pretty new to cake decorating, but I am very interested in learning everything I can, mostly by trial and error. So, I have volunteered to make an X-Box cake for my friends fiance. My question is, how far in advance can you put fondant on a cake? Does it need to be refridgerated? Also, If I want to make a cd, will fondant dry out enough to stand upright?

Thanks!

Well, I went ahead and decided to give it a try. I figured out that I HAD to refridgerate my cake because of the filling. Also, The Cd got harder, but not sturdy enough to stand up. I guess I needed to mix in some gumpaste?

Actually you don't have to refridgerate it, even if you used a filling. The fondant seals up anything inside and keeps the cake nice and moist. Since you did refridgerate it you will probably get some condensation when you take it out, but don't worry. Just let it sit and air dry and you'll be fine.
If you need your fondant stiff enough to stand upright you need to mix in some gumpaste (most do 50/50) or some tylose.

It did have some condensation, but I had let it sit for several hours before I dropped it off, so it had dried! And thank you for the gumpaste tip! I guess that will be my next adventure!
