I don't cook. I hate cooking, and I'm not good at it. But these cookies are awesome, and you could probably get away with using pre-made cookies instead of baking your own. So it's really more of "assembling," not cooking. Just a couple of cookies of your choice (or maybe it is one, snapped in half; I can't tell), lined with red icing (for gums), dotted with mini marshmallow teeth, and a couple almond slivers for the fangs, and BANG! You have a delicious Halloween party snack. For an extra gory treat, I would probably dab a bit of red food coloring onto those teeth, or at least onto the fangs.
