These recipes have a secret ingredient making them green. I'm going to tell you what that secret ingredient is, but you have to promise to keep it a secret. Because people don't seem to mind eating green cookies made with chemical food coloring, but for some reason, they're squeamish about eating cookies made from spinach. There, I said it. My secret green ingredient in these cookies is spinach.
