I have made muffins and cupcakes all my married life, and never had any trouble with them sticking to the liners until about two years ago. I have tried many paper liners, and they all stick. This last batch was the worst. I made pineapple muffins, just a basic muffin with a can of pineapple mixed into the dough. When we try to peel the paper off, it literally pulls the muffins apart. We are eating them with a fork right out of the paper liner. Anyone else had this issue and what kind should I buy that do not stick. I have never had to spray them with non-stick spray before and I hate to start now. What gives with these liners? I usually buy them in the baking section of our supermarkets.
