Instructions
1. Cook and Mash the Potato
- Peel and dice the potato into small chunks.
- Boil in water until fork-tender (10-12 minutes).
- Drain, mash until smooth, and let cool completely.
2. Make the Dough
- Combine mashed potato and 1 cup powdered sugar. Stir until smooth.
- Gradually add remaining powdered sugar, 1 cup at a time, mixing well. You’ll need 4-6 cups total, depending on the potato’s moisture.
- Add vanilla (if using) and mix.
3. Roll Out the Dough
- Dust a surface with powdered sugar.
- Roll the dough into a 1/4-inch thick rectangle using a powdered-sugar-dusted rolling pin.
4. Add the Peanut Butter Filling
- Spread peanut butter evenly over the dough, leaving a small border.
- Roll tightly into a log, starting from a short end.
5. Chill and Slice
- Wrap the log in plastic wrap and refrigerate for at least 1 hour.
- Slice into 1/4-inch pieces and serve.
Tips for Success
- Use a russet or starchy potato.
- Work quickly to prevent the dough from drying out.
- Add powdered sugar gradually.
- Chill before slicing for cleaner cuts.
Variations
- Cinnamon Swirl: Add cinnamon to the peanut butter.
- Chocolate: Use Nutella or chocolate spread instead of peanut butter.
- Nut-Free: Substitute sunflower seed butter or cookie butter.
Storage
- Refrigerator: Store in an airtight container for up to 5 days.
- Freezer: Wrap individually and freeze for up to 3 months. Thaw in the refrigerator.
