I like the brownie-like flavor of these cute little cookies, and I love how simple they are to make. They are easily hand-mixed, so don't drag out the mixer! I made a double batch using one whole egg in just 45 minutes from start to finish. I didn't refrigerate the dough, but next time I might because it was a bit sticky to work with. Judge doneness by touch rather than appearance, since once they start to "look" done, they are already overbaked. This recipe comes from Everyday Food magazine #16. I am including the vanilla variation, although I have not tried it yet.
