I made this recipe twice with horrible results. The first time i made it i followed the instructions exactly and they were undercooked. The second time i changed the tempature to 450 and let them bake for 20 minutes. When i took them out I actually thought i had burnt them. But once i let them cool, i cut one in half and they were still undercooked. I don't know. maybe i am doing something wrong, but i was really dissapointed.
