Holy spicy cookies, Batman! This is the second time I've attempted a chocolate/cayenne recipe. I originally tried a similar version of this cookie a few years ago. The recipe called for a TABLESPOON of cayenne pepper. It was just too powerful. The heat from the cayenne hit you almost immediately and the whole experience was less than enjoyable. With these cookies, I only use a TEASPOON of cayenne for the whole batch. The final product is a chocolate cookie with a spicy finish. The heat doesn't hit you upfront, but rather builds on your palate. I chose to keep the cookies plain - no frosting or topping. In the future, I may roll the dough into balls and then in turbinado sugar, flattening with the bottom of a glass before baking.
I have to warn you, if you don't like hot foods, this is NOT the cookie for you. My husband brought the batch to work in a baggie clearly labeled: CAYENNE. One of his coworkers popped one in her mouth and was not so pleased when the heat hit.
