I have to make a wedding cake for a Saturday wedding. I have another job and was curious how far in advance can I bake the cakes (if I spray them with a simple syrup) and how far in advance can I make the fondant decorations?
You can bake the cakes weeks ahead of time. Wrap the cake layers(after letting cool) in saran wrap, then heavy foil. They will be fine. You can make the icing, freeze that. You can make the fondant decos(don,t know what they are) and put in tupperware or something like that. I have made them and just put in fridge nite before and then let them come to room temp. few minutes , then put on top and sides of cake. They did great. I always prepare ahead of time and then my decorating day goes great. hth
You can make the cake weeks ahead and freeze it, no syrup needed. You could also do your buttercream ahead of time and get that out of the way. I don't work with fondant so not sure about that but some things like bows or figures need to dry so you should do them ahead.
