Old-fashioned potato candy dates back to the Great Depression, when frugal cooks turned simple, affordable ingredients into a sweet treat. Made with just three main ingredients—potatoes, powdered sugar, and peanut butter—this no-bake candy is a holiday favorite and makes a generous batch for gifting or sharing.
This recipe has been handed down through generations and remains a nostalgic Christmas classic.
In hard times, cooks relied on pantry staples. Mashed potatoes provided a smooth, neutral base that combined well with confectioners’ sugar and peanut butter to create a sweet, creamy candy without the need for baking.
This was my grandmother’s potato candy recipe, passed down and still a must-make around Christmas.
Ingredients in This Old-Fashioned Potato Candy Recipe
You only need three ingredients:
- 2 medium Russet potatoes (freshly boiled and mashed). Russets break down easily and hold less moisture, making them ideal.
- 7 cups confectioners’ (powdered) sugar — this quantity creates the firm, rollable dough the recipe requires.
- ½ cup creamy peanut butter for the filling; crunchy peanut butter can be used if you prefer a textured bite.
How to Make This Old-Fashioned Potato Candy
1. Scrub, peel, and boil the potatoes until fork-tender. Drain and mash the potatoes until completely smooth. Let the mashed potatoes cool to room temperature before proceeding.
2. In a large bowl, add about ½ cup of powdered sugar at a time to the cooled mashed potatoes, kneading as you go. Keep adding sugar until the mixture forms a firm, non-sticky dough. The exact amount of sugar can vary depending on the potatoes’ moisture.
3. Prepare a work surface with parchment paper and dust it lightly with powdered sugar. Flatten the dough into a rectangle about ¼ inch thick. Placing another sheet of parchment on top and using a rolling pin helps create an even layer.
4. Spread a thin, even layer of peanut butter over the dough rectangle.
5. Starting along the long edge, roll the dough up jelly-roll style as tightly as possible, using the parchment to help guide and lift the roll.
6. Wrap the log tightly in parchment paper and chill in the refrigerator for at least 1–2 hours so the filling and dough can firm up.
7. Remove the chilled log, unwrap, and cut into slices about ¼ inch thick. Store slices in an airtight container with parchment between layers and keep refrigerated.
What’s Needed to Make Potato Candy
- Saucepan to boil the potatoes
- Peeler or sharp knife to remove potato skins
- Potato masher (or ricer) to get a smooth mash
- Parchment paper for rolling and storing the candy
How to Store Potato Candy
Slice the chilled potato candy into ¼-inch rounds. Arrange slices in an airtight container with parchment paper between layers to prevent sticking. Stored in the refrigerator, the candy keeps well for up to one week.
Variations and Tips
For added texture, substitute crunchy peanut butter for creamy. The candy will be slightly lumpier but still delicious.
If you like, stir in 1–2 teaspoons of vanilla extract while you’re combining the mashed potatoes and sugar for a subtle flavor boost; the classic recipe does not include vanilla, and many families prefer it plain.
If your mixture is too soft or runny, ensure the potatoes are fully cooled and add powdered sugar gradually. A small amount of cornstarch can also help thicken the dough without changing the flavor.
FAQ
Does potato candy really contain potatoes?
Yes. Mashed potatoes are the binding base, but they don’t contribute a noticeable potato flavor. Instead, they give the candy a smooth, pliable texture once combined with powdered sugar.
Why is my potato candy runny?
Runny candy is usually due to warm or moist potatoes or adding sugar too quickly. Cool the mashed potatoes completely, add powdered sugar gradually, and knead until the mixture forms a firm dough. Adding a tablespoon or two of cornstarch can help if needed.
Can I use instant potatoes?
Instant potato flakes are not recommended. They often retain extra moisture and won’t form the solid, cohesive dough you get with freshly boiled russet potatoes.
