Could someone tell me why my cupcake liners are seperating from the cake?? Need help! I am unable to upload the pics at this time.

There are tons of threads on here about this very topic. Frequently, cheap liners seem to be a problem.

Or how the cupcakes were stored. Sealed up tight = not a good idea.

I've had this happen to me a number of times before I realized my sealed storage container was the problem. It caused the cupcakes to become so moist that the liners pealed away. I started to store them in cupcake boxes and this has helped. I find the foil liners "much" better than the paper ones.
