Since I made my cookies smaller, I baked for a slightly shorter time. I timed the oven for 5 minutes, then rotated my cookie sheet (because things facing the back of my oven brown quicker) and baked for another 5 minutes. They were perfect with each batch; I have to keep remembering what Alton Brown said during his chocolate chip cookie show; that if the cookies look done in the oven, then they are too done, so you should take your cookies out before they look done!
