1 medium potato
1 tablespoon butter
1 teaspoon vanilla extract
1 (1-pound) box powdered sugar
Peanut butter to taste (smooth or crunchy)
In small saucepan cover whole, unpeeled potato with water and boil until tender. Drain, peel and place in large mixing bowl. Beat with electric mixer; add butter and vanilla. Slowly add the powdered sugar, mixing until you have a stiff dough.
Roll out on a powdered-sugared surface. Spread with a layer of peanut butter. Roll up as for a jelly roll. Chill until firm and then slice into 1/2-inch confections.
Makes about 1 1/2 pounds.
