I was on Cookies and Cups blog and bumped into these treats.... Please visit cookies and cups blog to view the recipe. http://cookiesandcups.blogspot.com/2010/08/peanut-butter-cookie-cups-white.html. They are 100% delicious and SO easy to make. I made some slight modifications... I used a Peanut Butter Cookie recipe I found on epicurious/gourmet.... http://www.epicurious.com/recipes/food/views/Peanut-Butter-Cookies-105746. I baked them at 325 for 12 minutes. I also used a plain buttercream frosting... The White Chocolate Buttercream sounded delicious, but i had some buttercream already made... Not only do these taste great; they look "pretty" too! (warning: must LOVE peanut butter) ENJOY!
