Step 1

Peel and slice the potato. In a small saucepot, cover the potato slices with water and cook over medium heat until soft. Drain potato and place in mixing bowl. Beat until mashed. Add 1/2 sugar and mix well. Mix in the remaining sugar, scraping down sides as needed.

Step 2

Line a countertop with a sheet of waxed paper dusted with confectioner's sugar. Scrape out dough onto waxed paper and dust top with more confectioner's sugar. Roll out to a thickness of about 1/4 of an inch (don't go getting a ruler here, just eyeball it. This isn't rocket science). Spread dough with peanut butter and roll up like you are making cinnamon rolls. Once you have rolled it up into a log, roll the log up in your waxed paper and cut it in half. Place halves in a gallon zipper seal bag and store in the fridge until ready to serve.

Step 3

When ready to serve, remove waxed paper and slice it into 1/4 inch slices. Store leftovers in the refrigerator.
