Santa brought me some silicone bakeware for Christmas. So for New Years day I decided to use the muffin (12 part) pan (for lack of a better word). I had already washed them in warm soapy water and dried them. Well I made my cornbread as normal and poured the batter into the silicone muffin pan and said pan was on an aluminum baking sheet for support. Into preheated oven at 425 for about 15 minutes. I let them cool for about 30 minutes. Well the muffins stuck to the silicone and I had a heck of a time getting them out and only a few came out whole.
