Why do cupcake papers separate from the cupcakes after baking?

Somayya asks: Why do my cupcakes separate from the paper a day later?  I have tried paper cups and foil cups and the same thing happens.

Baking S.O.S. says: I’m glad you asked this question. I have been baking cupcakes a lot recently, and I am having the exact same problem!

In my case, I assumed the reason the liners were separating from the cupcakes is that I was spraying the liners with cooking spray before I poured the batter into them.  My guess is that the cooking spray was not only preventing the paper liners from sticking to the cupcakes–which is what I intended it to do–but also causing the papers to slip away from the cupcakes completely.

One of the very first lessons I learned in culinary school was the proper way to prepare pans for baking cakes: “Spray, Paper, Spray.”  And I still use that method to this day.  When making cupcakes, I always spray the paper liners with cooking spray because otherwise, you have the reverse problem, and the papers stick so much that when you try to peel them away from the cupcakes, they take half of the cupcake with them!

When you asked this question, I decided to do a little more research to see if there might be any possible remedies for this problem that other bakers have used.  I found the following suggestions helpful:

– Be sure to fill the cupcake pans full enough so that the batter will stick to the top of the paper liner, keeping it adhered.  Cupcake pans should be filled 1/2 – 2/3 full. (any fuller than that, and the batter will spill over the top, making a flat, messy cupcake top)
– Turn the cupcakes out of the pans as soon as they are finished baking.
If cupcakes are left in the pan too long while cooling, steam will condense between the cupcake and the pan, causing the liner to loosen.

I hope these suggestions will be useful–both to you AND to me!  Good luck!
