Whoopie Cookies

1. The beauty of having my daughter home from college (besides having her with us) is that I get her in the kitchen with me and every once in a while, I get to share her creations as I am doing with this recipe.  She follows Foodgawker and looks for things she likes and wants to make herself.  I do not know for sure that she did this in this case.
