Peanut Butter Pinwheel Candy

Instructions

1. Peel, dice, and boil the potato until tender, about 10-12 minutes. Drain and then mash well, using a potato ricer for best results. Allow the potatoes to sit at room temperature until completely cooled before making the dough.
2. In a large bowl, use a hand mixer to beat together the mashed potatoes, butter, vanilla, salt, and 1 cup of powdered sugar.
3. Add in remaining powdered sugar 1 cup at a time until you have a total of 6 cups of sugar. If the dough is not moldable in your hands and can't be rolled into a ball, continue to add more powdered sugar until it is firm enough to roll into a ball.
4. Cover and refrigerate the dough for 1 hour.
5. Once chilled, divide the dough into two pieces. Wrap one in plastic wrap and place it back in the fridge. Place the other on a clean surface that has been lightly dusted with powdered sugar. Dust the top of the dough with additional powdered sugar and use a rolling pin to roll it out into a rectangle that is 1/4 inch thick. Periodically lift the dough to make sure it's not sticking. Dust with more powdered sugar as needed to prevent it from sticking.
6. Once the dough has been rolled out, spread the peanut butter evenly across the top of it, leaving a small amount of space peanut butter-free around the perimeter.
7. Starting with the longer side of your rectangle, carefully roll it up into a tight log.
8. Use a sharp knife to slice into pieces about 1/2" thick. Repeat steps 5-8 with the remaining dough. Serve and enjoy.
