I am making a Jem and the holligrams cake for a friends birthday. I made the 2 9" cakes and froze them last night, I plan on covering it with a purple fondant and was hoping to use a cream cheese icing underneath and fill the layers with a vanilla custard. the party is for Saturday but i will be away to i have to have the client pick it up on Thursday night. Will the cake be ok if i make it on Wednesday night? how should it be stored?????

The custard filling means it needs to be refrigerated. To keep the refrigeration from ruining your fondant, store the cake in a cardboard box wrapped airtight in several layers of plastic wrap. Tell your customer to take the cake out of the fridge several hours before it's going to be served, but NOT to unwrap it until it's come to room temp and ALL the condensation has evaporated. Otherwise, condensation will form on your fondant and that will either crack it or melt it or both.
