Peanut Butter Chocolate Whoopie Pies

Be sure to save some peanut butter cups this Halloween for a great addition to the filling of these peanut butter whoopie pies. These are delicious! I brought them to work, and people could not stop eating. The peanut butter cups add more chocolate flavor and a great texture.
