Help, when I put my mini papers into the mini pans then put batter in them they like to pucker on one side.They are not perfectly round. there is like a pucker or crease like fold on every one of them. How do I get this to stop? TY cheffie

Buy grease-resistant or grease-proof cupcake liners. Regular paper liners suck.

Your liners are too big for your pan

Your liners are too big. Some of the wilton papers I've used do that in my pans.
