How far in advance can you put an edible image on a cake and let it sit?? I have a cake due Saturday and I would like to get the cake done tonight or tomorrow night. Is it going to be okay if it sits on the cake for a couple of days???

...an image can be placed on the cake a couple of days ahead of time with no problem. You can even store the finished cake (with the image on it) in the fridge too!
