Chocolate Lava Muffins

I believe this is an Alton Brown recipe. It is cakey on the outside and gooey chocolate on the inside. I have made these several times and they have always been a hit. Posting the recipe so I don't have to go searching for it next time I want to make it. Cook time is approximate, accounting for chill time.
