You read it correctly: Potato Candy!This recipe has been a favorite in my family for generations. Don’t be alarmed by the potatoes, they’re a critical ingredient that you’d never guess is hidden in this sweet old-fashioned candy!

My family loves making this potato candy around the holidays, especially for Christmas and Easter. You might even recognize the candy base as I’ve shared it before in my Easter Egg Candy. Be sure to read through the post for all of my most important tips before you begin!

Potato Candy (1)

If you’ve read this far you’re either really, really intriguedoryou grew up making your own Potato Candy and already know how amazingly delicious this recipe really is.

I’m guessing we lost some people with the title, but trust me, they’re missing out. You’re going to be so glad you stuck around (and I’m so grateful for you for trusting me on this one!).

This recipe came from my grandmother’s grandmother. While the potatoes may seem off-putting at first, I promise you that you won’t taste them in the finished product. They mostly serve to bind the candy “dough” together, and they do so without making it too sweet (if you left out the potatoes, you’d have a much too sweet buttercream candy that you couldn’t roll into this cute pinwheel shape).

I do have lots of tips and tricks for making this recipe, so let’s jump in. I highly recommend you read through this entire post before venturing out to make your own Potato Candy.

Tips for Making Potato Candy

  • Let the potatoes cool completely. Don’t refrigerate them, just leave them at room temperature once you’ve drained them until they are completely cooled, and then mash them until no lumps remain. If your potatoes are still warm when you add them to your mixture, there’s a good chance they’ll melt your butter and your sugar, resulting in a watery dough that you’ll have to toss out.
  • Add more sugar as needed. The dough will need to chill before you can roll it out, and it will be too tacky when first mixed up, but it should be somewhat shapeable. If it’s too sticky, you can always add more sugar, up to 2 cups more.
  • Dust your surface and your rolling pin with powdered sugar, it will make the whole process easier and your dough less likely to stick.

If the Mixture Becomes Watery, There’s a Good Chance You’ll Have to Start Over

Here’s my biggest warning about this recipe, a mystery I haven’t yet been able to solve: Every so often I’ll have a batch that turns out watery.

The first time this happened, I thought I hadn’t cooled the potatoes correctly and they melted the sugar. While that is definitely your most likely issue (and why I included the notes above) I’ve found that sometimes, even when I follow every instruction carefully and precisely, occasionally my dough turns out too runny. So runny that no matter how much sugar I add I just can’t salvage it.

Why this happens is still a mystery to me, and my best guess at this time is that it’s an issue with the potatoes. Perhaps they’re too old? Perhaps they’ve been boiled a minute too long? Not long enough? It may even have nothing to do with the potatoes (could it be the humidity?)!

If you have any suggestions I am ALL ears, I’ve spent so much time trying to solve this and have finally conceded the fact that this is just a risk of making this recipe. It only happens rarely now, especially now that I’ve learned to be so careful with cooling the potatoes (again, your most likely culprit), but it does still happen from time to time and I want you to be fully informed. It’s an issue that would typically cause me tonot publish a recipe, but this is one that’s been in my family for generations and I felt it deserved publishing, just with a warning.

Ingredients

  • ½ cup (105 g) plain mashed potatoes* see recipe notes for cooking instructions
  • ½ cup (113 g) salted butter softened
  • 6-7 cups (800-910 g) powdered sugar plus additional for dusting
  • 2 teaspoons vanilla extract
  • Creamy peanut butter for filling

Recommended Equipment

Instructions

  • Combine mashed potatoes, butter, and one cup of sugar in a large bowl and use an electric mixer to stir until combined.

    ½ cup (105 g) plain mashed potatoes*, ½ cup (113 g) salted butter, 6-7 cups (800-910 g) powdered sugar

  • Add remaining sugar, 1 cup at a time and stirring until combined after each addition. Once you've added 6 cups of powdered sugar, check the consistency. If the dough is not moldable in your hands and can't be rolled into a ball, continue to add sugar until it is firm.

  • Stir in vanilla extract.

    2 teaspoons vanilla extract

  • Refrigerate for at least 30-60 minutes (if you chill longer it may become too firm and brittle and will just need to sit at room temperature for 10-15 minutes until it is pliable).

  • Once chilled, divide dough into two pieces and place one piece on a clean surface that you've generously dusted with powdered sugar. Dust the surface of the dough with additional sugar, and use a rolling pin to roll dough out into a rectangle about ¼" thick (about 8x12"). If your dough is too sticky or falling apart, you may need to add more sugar, re-shape it into a ball, and start over.

  • Once dough has been rolled into a rectangle, spread evenly with peanut butter, leaving a small amount of space peanut butter-free around the perimeter of the dough.

    Creamy peanut butter

  • Starting with the longer side of your rectangle, gently but tightly roll into a log.

  • Use a harp knife to cut into slices about ¼-½" thick.

  • Repeat steps 5-8 with remaining half of dough.

  • Serve and enjoy. Store leftover candy in an airtight container in the refrigerator for up to a week.

Notes

*Potatoes

Use russet potatoes. I recommend piercing your potatoes all over with a fork and heating in the microwave, rotating the potato every several minutes, until potato is tender when pierced with a fork. Then remove the potato filling from the jacket/skin and mash until smooth.

I used to boil the potatoes and while this often works, I found this can sometimes cause the potatoes to retain water and make the mixture too watery to use.

Mashed potatoes must cool completelybefore adding sugar. Otherwise they will melt the sugar and you will end up with a very runny mess. I recommend allowing them to cool at room temperature rather than the fridge, as sometimes the condensation from the fridge can also make the mixture runny.

Cinnamon Cigars

Another (peanut butter-free) version of this candy can be made by rolling the filling into cigar shapes and rolling in 2 Tablespoons of cinnamon for Cinnamon Cigar Candy.

I've also used this potato candy recipe to make my old fashioned Easter Egg Candy.

      I’m so sorry to hear this! If you didn’t let your potatoes cool enough when you mashed them it will melt the butter and sugars and cause you issues. 🙁

    This sounds amazing and I hope to make it this weekend ! How much peanut butter (approximately) should I plan on using in the recipe ?

      Also! I wonder if I could mix some Nutella in with the peanut butter? 😍

      • Emily @ Sugar Spun Run

        Sounds delicious! Just make sure to reduce the peanut butter if you do, otherwise it could get messy when rolling 😊

    Would it be okay if I make and mash the potatoes and refrigerate them overnight to do in the morning? I’m so busy at the holidays.

    Reply

    • Sam

      Hi Christian! That will work, but it incorporates better at room temperature so you will want to let the potatoes come back to room temperature before using. 🙂

        Does anyone have an OLD recipe for potato candy made by using cubed potatoes and sugar.

      • Emily @ Sugar Spun Run

        Hi Carol! Have you given our recipe a try? It’s a very old family recipe and uses the ingredients you’re referencing.

        Silly question! I’m making this 😀 about how many potatoes makes 1/2 cup? 🤔

      • Emily @ Sugar Spun Run

        It depends on the size, but one medium potato should cover it 😊

        I’m wondering if some watery results (when how the potatoes are handled are not the issue) has to do with the butter? Different brands have different moisture (water) content in the butter. I didn’t realize this until making certain cookies and biscuits where the cheaper butter I bought did not work in the way it usually did. felt better to the touch, too
