I had a similar experience. After 15 minutes they were not done. We did 5 more minutes, and they didn't seem much closer, so my son put them back in and set the timer for 10 more minutes. Then I read this post and worried that 10 more minutes might be too long, so I had him check them right away. It turns out we only used 7 or 8 of that last 10 minutes because they are done. They are cooling now. I can't wait to try them.
