Ingredients
- 1 medium russet potato (about 1 cup mashed, cooled)
- 4 to 5 cups powdered sugar (adjust as needed)
- 1 teaspoon vanilla extract
- Pinch of salt
- ¾ to 1 cup creamy peanut butter (for filling)
Kitchen Equipment
- Medium saucepan
- Mixing bowl
- Potato masher or fork
- Rolling pin
- Wax paper or parchment paper
- Sharp knife
Step-by-Step Directions
Step 1: Cook the Potato
Peel the potato and cut it into chunks.
Boil in water until very soft (about 12–15 minutes).
Drain well and allow it to cool completely.
Mash until smooth with no lumps.
Step 2: Make the Candy Dough
In a mixing bowl, combine:
- Mashed potato
- Vanilla extract
- Pinch of salt
Add powdered sugar gradually, one cup at a time.
Mix until a soft dough forms that is no longer sticky.
The dough should feel similar to soft fondant.
Step 3: Roll Out the Dough
Place the dough between two sheets of wax or parchment paper.
Roll it into a large rectangle about ¼ inch thick.
Try to keep it even so the candy rolls neatly later.
Step 4: Add Peanut Butter Filling
Spread a thin, even layer of peanut butter over the rolled dough.
Leave a small border around the edges to prevent overflow.
Step 5: Roll and Chill
Carefully roll the dough into a tight log, starting from one long edge.
Wrap in wax paper and refrigerate for 1–2 hours until firm.
Step 6: Slice and Serve
Once chilled, use a sharp knife to slice into ¼–½ inch pinwheels.
Serve immediately or store in an airtight container.
