This is an Instructable created by wold630 (not to be confused with wolf630, who doesn't bake cookies, only little pigs) detailing how to make your own scary face chocolate chip cookies for Halloween. Basically it involves making regular chocolate chip cookies, then using a sculpting tool to carve eyes and mouth dents, using sugar pearls for eyeballs, almond slivers for teeth, and red and black food coloring markers for detail. Simple! So simple even I could do it. "Why is your kitchen on fire?" Unrelated. Okay, kind of related. I forgot I hid all my nudie mags in the oven.
Keep going for a couple more pictures.
Thanks to Joselyn, who agrees the scariest Halloween cookies have been and always will be oatmeal raisin cookies you mistake for chocolate chip.
