Holidays are the perfect time to enjoy candies, cookies, and treats, but why wait all year to make sweet treats? I say any time is a great time for something sweet. My mom is a fantastic candy maker and one of the things I look forward to is when she makes her peanut brittle, English toffee, and potato candy. 

Potato candy at its core is simply an old-fashioned candy you just can’t mess up. With only 3 ingredients (4 if you’re feelin’ craaaaazy) and no baking time, it’s so easy to make…and no it doesn’t taste like potato at the end, it tastes so sweet and kind of soft and cloudy. Just trust me on this!

Why This Recipe Works 

Potatoes — I mean, not only can you not call this “potato candy” without the potatoes, but you need the starches in the potato to turn the powdered sugar into something creamy that tastes more like fudge or divinity. 

Peanut butter — I say give me the peanut butter everything! It just works with this potato candy recipe. However, see below for more fillings you could use in this candy. 

Incorporating powdered sugar slowly — I suggest you add the last 4 cups of powdered sugar one at a time to get each cup incorporated into the mashed potato or you will end up with lumpy candy. Each cup will mix in easily, though it will get thicker as you add. 

Chill time — It’s waaaaay easier to cut this potato candy into pieces if you chill it for about 30 minutes first. Otherwise, your knife will just kind of mush everything together. So do allow for the candy to have some time alone in the fridge before cutting. 

Here’s How You Make It 

So now that you know what makes this recipe work, you probably want to know how to make potato candy right? Read on! 

1. Place the small (peeled) potato in a small pot, cover it with water, and then boil it until it’s very tender. Then, drain the water and transfer the potato to a large bowl. Mash the potato with a potato masher (or use a hand mixer) until it’s smooth and lump-free.
2. Next, add 4 cups of powdered sugar to the bowl with the potato and mix until blended (will be a sticky mess and this point). If opting to use vanilla, mix in now. Mix in the remaining powdered sugar, 1 cup at a time, until mixture is very thick (slightly thicker than cookie dough).
3. Now, lay down a large sheet of wax paper and sprinkle it generously with powdered sugar. Transfer the candy mixture to the wax paper and sprinkle the top of it with more powdered sugar so you can easily roll it out to a ¼-inch-thick rectangle.
4. You’ll then spread the peanut butter evenly over the flattened potato candy. Roll it up tightly (long side toward long side) into a long log. Wrap it up in the wax paper, cut the whole thing in half crosswise and put the two halves inside a large resealable bag. Seal the bag and chill the candy for at least 30 minutes or until it’s firm. Or, cut it just 30 minutes before you’re ready to serve it.
5. To slice, unwrap the candy and use a knife to cut it into 1-inch thick slices.
6. Serve or store in an airtight container in the fridge for up to 2 weeks.

Expert Tips 

• The traditional way to make this potato candy is to spread peanut butter in the center, but it’s 2021 and we live on the edge now, so other fillings are perfectly acceptable. Some of my favorite ways to mix it up include cookie butter, almond (or another nut) butter, Nutella, crunchy peanut butter, chocolate chips, sprinkles — go crazy! 
• I suggest between 6-8 cups of powdered sugar. It’s hard to predict what you’ll actually need. So start with the 4 cups, then do one at a time from there until your dough is kind of playdoh like. You want to be able to roll it so it can’t get too stiff, nor should it be too sticky. I guess if you have to make a few batches to get it just right, then you can have a taste-test with your family after! 
• If you are going to give some of this as a gift, I recommend putting small pieces of wax paper between each piece or layer in the container that you choose. Also remember to tell the receiver to keep the candy in the fridge.
