I usually make my cake a day befoe, add filling then freeze. I then decorate the night before, which leaves me staying up very late. My question: how far in advance can a cake be decorated and left in fridge with fondant and buttercream and the cake still taste good?

Thanks for your tips/suggestions!

I always had my cakes done by the afternoon of the day before (wedding on sat .... cake completely done no later than 4:00 pm on Friday). I never refrigerated my cakes. They sat on my countertops until I came in the next morning to load 'em up and deliver them.

cakes are not as fragile as people make them out to be. Once they are iced, the icing seals the cake, preventing the air from getting to the cake, which is what makes a cake dry out.

refrigerating a cake tends to accelerate the "going stale" process. Unless you ahve a perishable filling, there is no need to put the cake in the 'frig.

I was going to ask a similar question myself. I baked my cakes yesterday and froze them overnight. I was planning on icing them tonight then finish pipiping the design on tomorrow for delivery friday. Is that okay?
