These cookies are perfectly chocolately and the peanut butter chips make it like a cookie version of a peanut butter cup. The recipe is adapted from a traditional chocolate chip cookie recipe, so they have that familiar texture and chewiness.The cookies puff up and spread while baking, then flatten when cooling. Overbaking is to be avoided as you’ll end up with a dry, crunchy cookie. The cookies need to be slightly under baked when removed from the oven to ensure chewiness.
