This is an old fashioned candy recipe. Now if you’re thinking potato candy sounds weird, I can see where you’re coming from so I’m gonna let you know what to expect. This candy is kinda in the same taste category as Fudge or Divinity. It is just that good! You won’t be disappointed!
YOU CAN ADD A TEASPOON OF VANILLA IF YOU LIKE, BUT YOU DON’T HAVE TO. Y’ALL KNOW I LIKE THINGS AS SIMPLE AS POSSIBLE. YOU CAN ALSO LEAVE THE PEANUT BUTTER OUT AND JUST ROLL IT INTO BALLS, BUT OH MY GOODNESS, I LOVE THE PEANUT BUTTER!
Place potato into a pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until very tender, about 30 minutes. Drain. Transfer potato to a large bowl and mash until smooth. Stir vanilla extract into mashed potato.
Stir confectioners' sugar gradually into mashed potato until consistency is like cookie dough; add more confectioners' sugar if candy is too runny.
Sprinkle a large piece of waxed paper with confectioners' sugar and roll potato candy out into a rectangle 1/4 inch thick. Spread peanut butter onto candy. Roll candy and peanut butter into a tight spiral; wrap candy log in waxed paper. Refrigerate until firm, about 1 hour. Cut into slices to serve.
