As soon as I saw peanut butter, I knew it had to be a cookie. I will use any excuse to bake a sweet treat. During these What's Cooking challenges, I want to try something new unless I know I have a spectacular recipe that I would like to share. I found what sounded like a yummy double chocolate cookie and it lived up to its rating of five stars. I was a little nervous since it only called for one cup of flour. But my qualms were short-lived. I will be adding this recipe to my favorites and will make again.
