1 sm. potato
1 tbsp. butter
1 lb. 10X sugar
1 tsp. vanilla
1/3 c. peanut butter

Peel cooked potato. Mash and add butter. Add sugar, 1/3 at a time, beating until smooth and well blended. Mix in vanilla. If mixture is not stiff enough to roll add more sugar. Roll out between 2 sheets of wax paper until 1/8 inch thick. Spread with peanut butter. Roll up like a jelly roll. Chill for one hour, then slice into 1/4 inch pieces. Let ripen one day before eating.
