Healthy, tasty, moist muffins which are a fall tradition at my house. Can be made with canned or fresh pumpkin. Now that I have two reviews stating that they don't cook all the way through, I have to assume that it doesn't work well for jumbo muffins, only smaller ones. I have always made smaller ones (they go further) and I have never once had a problem with them not cooking all the way through. My most sincere apologies for the problems you have had, and my sincere thanks for trying them anyway.
