Sent by JulieEditor: Excellent question, and something I just recently faced myself with a batch of gingerbread cookies. When color isn't a clue, I usually go by feel. I pull the cookies from the oven when the edges of the cookies feel dry and set, but the middles are still soft and slightly puffy.
Readers, do you have other ways to tell when dark-colored cookies are done?
