Do you bake using the new, flaxable, non-stick, silicone muffin tins and cake pans?
Since you have personally had the experience of your cupcakes seemer a bit more dense, you might want to try just baking them for a little less time. I did find instructions for one brand of silicone bakewear that says you may have to adjust your baking time by 5 or 10 minutes. Although I’ve had excellent results with these pans, I did do a bit of Internet research after reading your question. I can’t find anything negative having to do with the quality of the baked product. Most of the negatives I found had to do with the pans being a bit more difficult to handle because they are flexible, but overall all of the revues I found, even from chef’s, were positive.
