I once made a Barbie cake covered in fondant, which was left on the counter for several days. By the time it was cut, I noticed that it had started to develop mold inside. Living in Florida the weather is very humid so that may have been the problem. if the lady is not cutting the cake for a week – I highly recommend refrigerating it. She may want to cover it with Saran Wrap (cling wrap), put it inside a cake box well sealed in a really cold refrigerator. It should be OK.
