Oh man! These are wicked. These are perfect. They are wicked perfect and I'm not even from Boston! If you haven't been introduced to "The Chewy" by Alton Brown, it's time you gave this a try. I followed the recipe exactly except I put 4 M&M's on top of the dough before I put them in the oven. I only put 6 cookies per cookie sheet and I cooked them for a total of about 7 minutes. The recipe called for 14 minutes! My oven cooks so hot. I would really watch that first batch to see how long it takes for them to get brown and crispy on the outside edges.
Hope you like these as much a I did!
