Ingredients You’ll Need
What makes this Old Fashioned Potato Candy Recipe so special is its simplicity. With just a handful of pantry staples, every ingredient plays a vital role in transforming humble components into a luscious final treat. From the subtle creaminess of mashed potato to the rich depth of peanut butter, each element contributes to the unique texture and nostalgic flavor that makes this candy a standout.
- 1 small russet potato (about 1/2 cup mashed): Provides moisture and a smooth texture without overpowering the sweetness.
- 4 to 5 cups powdered sugar (as needed): The key sweetener that turns the mixture into a firm, workable dough perfect for rolling.
- 1/2 teaspoon vanilla extract: Adds a delicate fragrance and enhances the overall flavor of the candy.
- 1/2 cup creamy peanut butter: The star filling offering creamy richness and a perfect balance to the sugary dough.
How to Make Old Fashioned Potato Candy Recipe
Step 1: Prepare the Potato Base
Begin by peeling your small russet potato and boiling it until it is tender enough to mash smoothly. This step is crucial because lumps can ruin the candy’s delicate texture. After mashing, make sure to cool the potato completely to room temperature before moving on. This prevents melting the powdered sugar too soon and keeps your candy dough at just the right consistency.
Step 2: Make the Candy Dough
In a large mixing bowl, pour in the vanilla extract, then gradually add powdered sugar, about a cup at a time. Stir continuously as you go because you’re aiming for a stiff dough that holds together without being sticky or crumbly. You might find yourself using anywhere from 4 to 5 cups—trust your hands and eyes to know when the dough is perfect, dense but pliable.
Step 3: Roll Out the Candy Dough
Take your newly formed dough and place it between two sheets of wax paper. This makes rolling out much easier and mess-free. Roll it out into a rectangle about 1/4 inch thick. The uniform thickness ensures an even candy roll with consistent pieces.
Step 4: Add the Peanut Butter Layer
Spread the creamy peanut butter evenly across the surface of your rolled-out dough. This is where you get that luscious swirl of flavor inside each bite, with the peanut butter perfectly complementing the sweet potato-sugar dough.
Step 5: Roll and Chill
Starting from the long side, roll the dough tightly into a log shape, taking care to keep the roll snug and neat. Wrap the log in wax paper and chill it in the refrigerator for at least an hour. This resting period firms the candy, making it easier to slice without squishing or crumbling.
Step 6: Slice and Serve
Once chilled, slice your candy log into rounds about 1/4 inch thick. Each slice reveals the beautiful peanut buttery spiral that makes this Old Fashioned Potato Candy Recipe instantly recognizable and irresistibly delicious.
How to Serve Old Fashioned Potato Candy Recipe

Garnishes
Keep it simple with a light dusting of powdered sugar on top to add a bit of sparkle and extra sweetness. If you want to get a little fancy, a tiny smear of peanut butter with a few crushed peanuts can elevate the presentation without overpowering the classic flavor.
Side Dishes
This candy pairs wonderfully with a hot cup of black coffee or a creamy glass of milk, creating a perfectly balanced dessert moment. If serving at a party, consider alongside other nostalgic sweets for a charming vintage dessert spread.
Creative Ways to Present
Display the slices neatly arranged on a wooden board for a rustic feel or stack them in a cute glass jar tied with a ribbon for gifting. Wrapping individual rounds in wax paper and tying with twine creates delightful homemade favors that instantly evoke a warm, old-fashioned vibe.
Make Ahead and Storage
Storing Leftovers
Your Old Fashioned Potato Candy Recipe keeps best in the refrigerator, wrapped tightly to prevent drying out. Stored this way, it will stay fresh and tasty for up to one week, making it a perfect make-ahead treat for busy days.
Freezing
While freezing is possible, it’s not generally recommended because the texture can change once thawed. If you do freeze your candy, wrap tightly and use within a month for best results. Thaw in the refrigerator before slicing to retain firmness.
Reheating
This candy is best enjoyed chilled or at room temperature. Reheating is unnecessary and may cause the peanut butter filling to become oily and the candy dough to soften too much. Just let it sit out for a few minutes if too cold straight from the fridge.
FAQs
Can I use a different type of potato for the candy?
Russet potatoes are ideal because they have a mild flavor and the right starchiness, but you can try other starchy potatoes. Just make sure they’re well cooked and mashed smooth for the best texture.
Is it possible to make this candy allergy-friendly?
Absolutely. Swap out the creamy peanut butter for almond butter or sunflower seed butter, especially if peanut allergies are a concern. The candy will still have that deliciously creamy swirl.
Why does the dough sometimes get too sticky or too dry?
The moisture content of the mashed potato varies, so adjust the powdered sugar carefully. Add sugar gradually until you reach a firm, dough-like consistency that isn’t sticky. If it’s too dry, a tiny bit of milk or cream can help loosen it.
Can I add flavors or colors to the candy dough?
Yes! Adding a few drops of food coloring or a flavored extract like almond or maple can personalize your candy. Just be sure not to add too much moisture, or the dough consistency could be affected.
How long does the candy need to chill before slicing?
At least one hour in the refrigerator is recommended to firm up the log. This chilling step ensures clean slices with intact spirals and prevents the candy from crumbling or squashing.
Final Thoughts
The charm of this Old Fashioned Potato Candy Recipe lies in its simplicity and the surprising transformation of humble ingredients into a cherished treat.

Instructions
- Prepare the potato: Peel and boil the russet potato until tender, then mash it thoroughly until completely smooth and lump-free to ensure a creamy dough base.
- Cool the mashed potato: Allow the mashed potato to cool to room temperature to prevent melting the powdered sugar in the next step.

- Add the peanut butter: Spread the creamy peanut butter uniformly over the surface of the rolled dough, covering every inch to ensure every bite has a peanut butter flavor.
- Roll the candy: Starting from the long side of the rectangle, carefully roll the dough into a tight log shape, using the wax paper to help guide the roll without sticking.
- Chill the candy: Wrap the rolled log tightly in wax paper and refrigerate it for at least 1 hour to firm up, making it easier to slice.
- Slice and serve: Once firm, remove the candy from the refrigerator and slice into 1/4-inch thick rounds. Serve chilled for best texture and flavor.
Notes
- This candy is very sweet, so small pieces go a long way.
- For peanut-free versions, substitute almond butter or sunflower seed butter.
