Fondant And Rtk Question, Help Please!
Decorating By Deannamac Updated 2 Oct 2009 , 2:27pm by CakeMommyTX
I am making a calculator cake out of rice krispies for a client. I have no choice but to make it the night before she wants to pick it up due to my other job. My question is; if i make the rtk cake and cover it in fondant the nite before, will it stay fresh until the following nite??
I dont want to give her a stale rtk cake with dried up fondant....
Thank you!
thanks for the reply rylan, since this rtk calculator isnt just for show...what would be the best choice to cover the rtk in so the fondant will stick? ive read buttercream icing, i just wonder if that will taste good on top of rtk...
any thoughts?
No problem =]
You can use ganache or buttercream under fondant--that will help things smoothen out. I prefer to use two layers of fondant. I just rub shortening all over the RKT and lay my first piece of fondant. I then lay a second piece to get a smoother finish.
I coat my RKT with white chocolate, it holds the shape and helps smooth out any bumps.
Just make sure the melted chocolate doesn't alter the shape of the RKT cake!
I attempted to make rkt egg shapes one time, I dipped them in melted chocolate, not even considering the fact that this would make the marshmallows melt again, it was a disaster!! lol! Ganache is easier as you can pour and/or spread it when it is no longer hot. 
I was just coming onto the forum to ask the very same questions that have been answered in this post! Thanks for asking the question Deannamac.
If you let the chocolate sit for a few minutes and cool down it won't warm up the marshmallows and change the shape.
I also don't dip the RKT I give it a chocolate rub down with my hands, messy but very effective.
And since chocolate self levels it fills in all the cracks and bumps and leaves you with a smooth surface.
When you need to cover in fondant you don't need to add anything to make it stick, just use the warmth in your hands when your smoothing the fondant , it will melt the chocolate just enough for the fondant to stick.
