1. Prep the Potatoes
- If using leftovers, ensure they’re plain and cold.
- If not, boil 1 small potato, mash with just enough water to smooth, then refrigerate until cold.
2. Make the Dough
- In a bowl, combine cold mashed potatoes and powdered sugar, 1 cup at a time, stirring well after each addition.
- After ~4 cups, the mixture will shift from paste to soft, pliable dough (like Play-Doh).
- Add more sugar if sticky; if too dry, lightly dampen hands and knead gently.
3. Roll Out the Dough
- Dust a clean surface with powdered sugar.
- Roll dough into a 12×8-inch rectangle, about ¼-inch thick. Keep edges neat.
4. Spread & Roll
- Warm peanut butter slightly (10 sec in microwave) for easy spreading.
- Spread evenly over dough, leaving a ½-inch border on one long edge.
- Starting from the opposite long edge, roll tightly into a log (like a jelly roll).
5. Chill & Slice
- Wrap log in parchment or wax paper; refrigerate at least 1 hour (or freeze 30 mins).
- Slice into ½-inch pinwheels with a sharp knife.
- Dust lightly with powdered sugar before serving.
