I would like to know how long a cake would last if I make it and decorate it on Tuesday and the cake is needed for Sunday? and how should I store it?
Unfortunately I have have to go to hospital and still have 1 cake to do before I go on the Wednesday and I will be there for a week.
For that length of time, I'd freeze it:
Box the completed cake. Wrap box in several layers of saran and foil. Freeze.
24 hrs. before serving, place wrapped box in fridge.
A few hrs. before serving, place wrapped box on counter.
Right before display/serving, unbox cake.
Thank you very much for your help. It has relieved a bit of stress.
