1/2 c. mashed potatoes (without butter or milk added) - plain
1 lb. confectionery sugar
1/2 tsp. vanilla

Put mashed potatoes into a bowl, slowly add 1 pound confectionery sugar. Keep beating and add 1/2 teaspoon of vanilla. Beat good. Place half of the mixture onto a sheet of plastic wrap sprinkled with a little confectionery sugar. Do the same with the other half. Roll out to a circle.

Spread creamy peanut butter over each half and roll up carefully and cover tightly with the plastic wrap you rolled it out on. Keep in refrigerator overnight, then slice after unrolling the paper off. Keep what you are not eating right away tightly covered and in refrigerator.
