im planning to make my own marshmellow fondant and was a little confused.. i was going to use a cookie dough filling in between the layers of cake then cover the whole thing with buttercream then lay fondant over the frosted cake

is that correct or no?

i dont want the cake to sweat or get yucky

should a fondant covered cake be refrigerated? it will have fondant and modeling chocolate figures on it if that makes a difference

Yes you want a little frosting under the fondant, it evens out the cake, sorta fills in any little imperfections so you can get a smooth looking fondant. No need to refridgerate.

you always need something under fondant, whether bc or some kind of jam, to get the fondant to stick to the cake.
most people do a crumb coat of bc, thickness up to yourself.
you only really need to refridgerate a cake if it has a perishable filling. some people have problem refidgerating fondant anyway.

I prefer a really light crumbcoat of buttercream...better yet, use ganache.

Watch that cookie dough...I pulled raw dough out of my grown child's hand the other day...raw eggs...

its not real cookie dough.. there is no raw eggs but there is butter, milk, pudding and whipping cream in the filling so idk if i should refridgerate it and then cover it in fondant and decorate it the morning im gunna be cutting it or what.... so lost

im no good at determining if recipes need refridgerated or not. i dont know if the pudding can stabilize the dairy or not. im sure you can research online if no one gets back to you here.
you can refridgerate decorated cakes, but you have to be wary of condensation on the fondant, some times it can cause problems, sometimes it doesnt. if you refridgerate the cake before fondanting, you are best to let the cake come to room temperature to avoid problems.

I've gotta try that one bsawyer78! However, jennybean, I can be of no assistance-sorry.

I know, but that was before your food could kill you.
