Boil potato until very tender. In small bowl, mash potato with fork or masher. Add 3 1/2 cups of confectioners' sugar slowly until thick dough like consistency. Spread remaining sugar on flat surface and roll out dough evenly. Spread on peanut butter and chocolate.Roll into log and cut into 1 inch pieces! Yummy!
This recipe was made every year at Christmas, without the chocolate, until my great grandmother passed away. I recently decided to add melted chocolate...just to spice it up a bit!
