This 3-ingredient depression era potato candy is the kind of recipe a grandma like Nana Clara would pull out when money was tight but she still wanted something special on the table. It turns leftover mashed potatoes, a bag of powdered sugar, and a scoop of peanut butter into the sweetest little pinwheel candies. I didn’t believe such simple ingredients could make a whole platter disappear until I watched my own family hover around the dish at a picnic, sneaking piece after piece. It’s old-fashioned, budget-friendly, and a fun little project to make with kids on a quiet afternoon.
Serve these potato candy pinwheels chilled on a glass rectangular serving dish so everyone can see the pretty white roll with the brown peanut butter swirl. They’re sweet enough that you only need a couple of pieces per person, so they’re perfect alongside coffee for the adults and cold milk for the kids. At picnics or potlucks, I like to set them next to salty snacks like pretzels or popcorn—the sweet-and-salty mix keeps people coming back for ‘just one more.’ They also sit nicely on a cookie tray during the holidays, tucked between chocolate chip cookies and fudge for a nostalgic touch.
3-Ingredient Depression Era Potato Candy
Servings: 24
Ingredients
1/4 cup plain mashed potatoes, cooled (no butter, milk, or seasoning)
4–5 cups powdered sugar, plus extra for dusting
1/2 cup creamy peanut butter
Directions
Make sure your mashed potatoes are plain and cool: If you’re using leftover mashed potatoes, they should be plain—no butter, milk, salt, or pepper. If they are seasoned, start with fresh potatoes: boil, mash with just a splash of water if needed, and cool completely in the fridge. You want 1/4 cup of smooth, cold mashed potatoes.
Start the candy dough: In a medium mixing bowl, add the 1/4 cup cooled mashed potatoes. Stir in 1 cup of powdered sugar at a time, mixing well after each addition. At first it will look thin and odd, but keep going. Add sugar until a soft dough forms that you can pick up without it sticking badly to your fingers. This usually takes around 4–5 cups, depending on how moist the potatoes are.
Adjust the texture: The dough should feel like a soft sugar cookie dough—pliable but not wet. If it’s sticky, sprinkle in more powdered sugar, a couple of tablespoons at a time, until it firms up. If it gets too stiff and crumbly, you can very lightly dampen your hands with water and knead it just a few times to bring it back together.
Chill the dough briefly: Shape the dough into a flat rectangle, wrap it in plastic wrap, and refrigerate for about 20–30 minutes. This makes it easier to roll out without tearing, especially if your kitchen is warm.
Prepare your rolling surface: Lay a sheet of parchment paper or wax paper on a speckled granite or other clean countertop. Dust the paper and a rolling pin lightly with powdered sugar so the dough doesn’t stick. If you don’t have parchment, you can dust the counter directly and use a little extra sugar as you roll.
Roll out the dough: Place the chilled dough on the prepared surface. Roll it into a rough rectangle about 1/4 inch thick. Aim for roughly 8 x 10 inches, but don’t stress about perfect edges—this is a humble, homey candy. If the dough sticks, dust lightly with more powdered sugar on top and underneath.
