I want to decorate a cake now with the gumpaste decorations I made and then put it back in the fridge so the icing has time to get cold and also to hold the decorations on better. I also want to keep the cake cold but don't want to decorate at the last minute under pressure. Will the gumpaste get ruined or soft in a couple of hours or will there be any other problems? The cake will be covered in the fridge in a plastic store-bought cake container and an old fashioned metal cake plate with cover. TIA.

i wouldn't cover the cake. The only time i have had fondant/gumpaste decorations melt in the fridge was when they were covered with plastic or in a tupperware container.

okay, thanks. I'll just do it at the last minute instead of trying to refrigerate. I have to cover them in the fridge because I don't have any room left in there and I have to stack them in their containers.

they would be okay if they were in boxes, but something about that plastic always does me in.
