Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 1/2 cups powdered sugar, plus extra for kneading and dusting
1/3 cup plain mashed potatoes (completely cooled, no butter, cream, or seasoning added)
1/2 teaspoon pure vanilla extract
1/8 teaspoon fine salt
1/3 cup creamy peanut butter
Directions
In a large mixing bowl, combine the mashed potatoes, powdered sugar, vanilla extract, and salt. Stir until the mixture begins to come together into a soft dough.
Lightly dust a clean work surface with powdered sugar. Turn the dough out onto the surface and knead gently, adding small amounts of additional powdered sugar as needed. Continue kneading until the dough becomes smooth, pliable, and no longer sticky.
Divide the dough evenly into three portions.
Using a rolling pin dusted with powdered sugar, roll one portion into a rectangle approximately 5×8 inches and about 1/8 inch thick.
Spread about 1 1/2 tablespoons of creamy peanut butter evenly over the surface, leaving a small border around the edges.
Starting from the long side, roll the dough up tightly into a log, jelly-roll style.
Wrap the roll tightly in plastic wrap and place it in the refrigerator to chill until firm, about 30 minutes.
Repeat the rolling, filling, and wrapping process with the remaining two portions of dough.
Once fully chilled, unwrap each roll and slice into 1/4-inch thick pinwheels. Serve at room temperature for the best texture.
Servings and timing
Servings: Approximately 6 dozen pinwheels (about 72 pieces)
Prep Time: 25 minutes
Chill Time: 30 minutes
Total Time: 55 minutes
Variations
Chocolate drizzle: After slicing, drizzle the pinwheels with melted semi-sweet chocolate and allow them to set before serving.
Nut butter swap: Substitute the peanut butter with almond butter or cashew butter for a slightly different flavor profile.
Nut-free option: Use a sunflower seed butter or other nut-free spread if needed.
Cinnamon twist: Add a small pinch of cinnamon to the dough for a warm, spiced flavor.
Thicker rolls: For a more candy-like center, spread the peanut butter slightly thicker before rolling.
Storage/Reheating
Refrigerator: Store the pinwheels in an airtight container with parchment or wax paper between layers. They will keep well for up to 1 week.
Freezer: The rolls can be frozen whole or sliced. Wrap tightly in plastic wrap and place in a freezer-safe container. Freeze for up to 2 months.
Serving after storage: Allow the candy to come to room temperature before serving for the softest, creamiest texture.
Reheating is not necessary, as this is a no-bake candy best enjoyed at room temperature.
FAQs
Why does this recipe use mashed potatoes?
Mashed potatoes act as a binder and create a smooth, pliable dough when combined with powdered sugar. They do not make the candy taste like potatoes.
Can I use instant mashed potatoes?
Instant mashed potatoes are not recommended. Real, plain mashed potatoes provide the proper texture and consistency needed for the dough.
Why is my dough too sticky?
The dough likely needs more powdered sugar. Add small amounts at a time while kneading until it becomes smooth and no longer sticky.
Why is my dough too dry or crumbly?
This can happen if too much powdered sugar is added. Knead gently and, if necessary, add a tiny amount of mashed potatoes to restore moisture.
Do the mashed potatoes need to be completely plain?
Yes. They should not contain butter, cream, salt, or seasonings, as these can affect both flavor and texture.
Can I make this ahead of time?
Yes. Potato candy stores well in the refrigerator or freezer, making it a great make-ahead holiday treat.
How thin should I roll the dough?
Aim for about 1/8 inch thick. Rolling it too thick may make the pinwheels bulky, while rolling too thin can cause tearing.
Can I double the recipe?
Yes. Simply double all ingredients proportionally. Be prepared to use extra powdered sugar for kneading and dusting.
Does this candy taste like potatoes?
No. The finished candy tastes sweet and creamy, similar to a white chocolate peanut butter treat.
How do I get clean slices?
Chill the rolls thoroughly before slicing and use a sharp knife. Wiping the knife clean between cuts also helps create neat pinwheels.
