Recipe Details
Servings: About 24 small pinwheels
Prep Time: 20 minutes
Chill Time: 1 hour
Total Time: 1 hour 20 minutes
Ingredients
- ¼ cup plain mashed potatoes, cooled
- 4 to 5 cups powdered sugar, plus extra for dusting
- ½ cup creamy peanut butter
Optional Nut-Free Substitute
- Use sunflower seed butter instead of peanut butter
Important Ingredient Notes
Use plain mashed potatoes only. Do not use potatoes with butter, milk, salt, pepper, or seasoning. Added fat or liquid can keep the dough from forming properly.
The potatoes must be completely cooled before mixing. Warm potatoes will make the dough sticky and difficult to roll.
If your powdered sugar has lumps, sift it first for a smoother dough.
Instructions
Step 1: Prepare the Potatoes
If using leftover potatoes, make sure they are plain, cold, and free from butter, milk, or seasoning.
If making fresh potatoes, boil one small potato until tender. Mash it smoothly with just a tiny amount of water if needed, then chill completely before using.
Step 2: Make the Candy Dough
Place the cold mashed potatoes in a mixing bowl.
Add powdered sugar one cup at a time, stirring well after each addition. At first, the mixture may look loose and sticky, but as more sugar is added, it will turn into a soft, pliable dough.
After about 4 cups of powdered sugar, the mixture should feel smooth and rollable, similar to soft play dough. If it is still sticky, add more powdered sugar a little at a time.
Step 3: Roll Out the Dough
Dust a clean work surface with powdered sugar.
Place the dough on the surface and roll it into a rectangle, about 12×8 inches and around ¼ inch thick.
Try to keep the edges as neat as possible so the pinwheels look even when sliced.
Step 4: Add the Peanut Butter
Slightly warm the peanut butter for about 10 seconds in the microwave to make it easier to spread.
Spread the peanut butter evenly over the dough, leaving about a ½-inch border on one long edge.
Step 5: Roll Into a Log
Starting from the opposite long edge, carefully roll the dough into a tight log, just like a jelly roll.
Roll slowly and gently to keep the filling inside and prevent cracking.
Step 6: Chill
Wrap the log in parchment paper or wax paper.
Refrigerate for at least 1 hour, or freeze for about 30 minutes, until firm enough to slice.
Step 7: Slice and Serve
Use a sharp knife to cut the chilled log into ½-inch pinwheels.
Dust lightly with powdered sugar before serving, if desired.
Serving Suggestions
Serve potato candy chilled with a cup of coffee, hot tea, or cold milk.
For parties and holidays, arrange the pinwheels on a pretty serving plate or glass dish. They also look beautiful on a dessert tray with fudge, cookies, divinity, or other old-fashioned sweets.
For a sweet and salty contrast, serve them with pretzels, salted nuts, or popcorn.
Helpful Tips
If the dough is too sticky, add more powdered sugar a little at a time until it becomes easy to handle.
If the dough feels too dry, lightly dampen your hands and gently knead it until smooth.
Use commercial creamy peanut butter for the easiest spreading and best texture. Natural peanut butter can sometimes be too oily and may make the candy difficult to roll.
Chilling is important. Do not skip this step, or the candy may be too soft to slice cleanly.
Make-Ahead and Storage
Store potato candy in an airtight container in the refrigerator for up to 1 week.
Place parchment paper between layers to keep the pinwheels from sticking together.
You can also freeze the whole log before slicing. Wrap it tightly and freeze for up to 2 months. Thaw in the refrigerator before slicing.
