Chocolate and peanut butter are a classic combination. Before WowButter was invented, this taste sensation was off-limits to anyone with a peanut allergy. Well, I have something even better: WowButter Pillow Cookies. And they are magical. I've made mine gluten-free but if you don't need to be on a gluten-free diet, just omit the xanthan gum from my recipe and use regular flour.
