This cookie isn't your average cookie.....it's EVIL. Pure Evil. Why? It's a cookie/brownie combo! Yeah. You heard me. Make some cookie dough. Make some brownies and cool them off. Combine the brownie into the cookie dough, bake it, and well, there you have it. Bakeralla calls them Pillow Cookies. I call them the death of a perfectly good diet. Check out the recipe and make some. Do it for me, cause I'm wiping this from my memory. I never saw this. Nope. It doesn't exist.
