Ok Garden Baker, I put the question out on a couple of my fb decorating pages. The consensus is…No to both refrigerating and freezing. Many feel the sugar sheet isn’t stable enough to be frozen. Most everyone feels if you must refrigerate/freeze the cake, add the sugar sheet afterwards. Just before pickup or delivery. You didn’t say whether you were applying to a bc or fondant covered cake. Fondant sweats when removed the fridge/freezer. So I could see the S S collapsing with the condensation. Now bc covered might be different. You just might get away with a refrigerated bc cake with a S S.
