Old-Fashioned Potato Candy Recipe (Vintage Southern Sweet)

If there’s one treat that instantly transports me back to Sunday potlucks and holiday cookie tins, it’s potato candy. This humble yet irresistible confection—made with mashed potato, confectioners’ sugar, and a swirl of peanut butter—originated in Appalachia and quickly found its way into kitchens across the South. Despite its odd name, this candy contains no actual potato flavor; instead, the potato’s starch gives the candy its pliable, fondant-like texture.

Picture this: your grandmother, apron on, peeling a steaming hot baking potato. After mashing and cooling, she’d knead in clouds of powdery sugar until a soft dough formed. Then came the fun part—rolling it out, spreading peanut butter, and rolling it up into tight logs before chilling. When you slice those logs, each piece reveals creamy white and nutty brown swirls that look almost too pretty to eat.

Today, I’m excited to share the ultimate potato candy recipe that has been in my family for generations. Whether you’re new to vintage candies or a long-time fan, this tutorial will guide you through every step: from selecting the perfect potato to troubleshooting sticky dough. Plus, I’ll offer tips for flavor variations, troubleshooting common issues, and pairing suggestions to make your candy spread shine.

So let’s dust off our mixing bowls and bring this old-fashioned delight back to life. Ready to roll? Let’s get started on the sweetest blast from the past!

Ingredients for Potato Candy

1 large baking potato (about 1½ cups mashed), cooled completely
4–5 cups confectioners’ sugar, sifted
1 teaspoon pure vanilla extract
½ to ¾ cup smooth peanut butter (adjust for thickness)

Equipment: Mixing bowl, rolling pin, parchment paper or silicone mat, sharp knife

Step-by-Step Instructions

1. Cook & Cool the Potato

First, wash, pierce, and bake the potato at 400°F (200°C) for 45–50 minutes until tender.
Then, allow it to cool completely—warm potato will melt the sugar, resulting in runny candy.

2. Prepare the Candy Dough

After cooling, peel and mash the potato in a bowl until smooth and lump-free.
Next, stir in vanilla extract.
Gradually, add sifted confectioners’ sugar, about one cup at a time, stirring until a stiff dough forms. You may need 4–5 cups depending on potato moisture.

3. Roll Out the Dough

Lightly dust a work surface and rolling pin with a bit of sugar or cornstarch.
Roll the dough into a thin rectangle, roughly ¼-inch thick, about 8×12 inches.

4. Spread & Roll

Carefully, spread a thin layer of peanut butter over the dough, leaving a small border.
Starting at one long edge, tightly roll the dough into a log, jelly-roll style.
Wrap in plastic wrap and chill for at least 2 hours (or until firm).

5. Slice & Serve

Unwrap the log and place on a cutting board.
Using a sharp knife, slice into ½-inch thick rounds. Wipe the knife between cuts for clean edges.
Arrange on a platter or cookie sheet and let air-dry for 30 minutes to set.

Tips & Variations

Nut Butter Swaps: Try almond butter, cashew butter, or sunflower seed butter for allergy-friendly options.
Chocolate Twist: Add a layer of melted chocolate or cocoa powder to the sugar before kneading for a chocolate swirl.
Citrus Zing: Stir in a teaspoon of orange or lemon zest into the dough for a bright flavor.
Texture Note: If dough is too sticky, add more sugar; if too dry, mash in a teaspoon of milk.
Make-Ahead: Store slices in an airtight container between parchment layers for up to one week, or freeze for longer storage.
Decorative Touch: Roll slices in colored sugar sprinkles or crushed nuts before chilling for a festive look.

Serving Suggestions

Serve these potato candy slices alongside your favorite holiday cookies, fudge, or Chocolate Truffle Fudge for a nostalgic candy table. They also pair beautifully with a cup of hot cocoa or coffee. Package stacks of slices in cellophane bags tied with ribbon for charming homemade gifts.
