Fudgy Purple Sweet Potato truffles in a white bowl

One of my frequent go-to afternoon “pick-me-up” snacks has been a simple plate of baked purple sweet potato slices drizzled with a little peanut butter and a few chocolate chips. One afternoon, while looking at my favorite snack, I thought, “Why not give this a Sweet Spin and turn it into a portable, fun treat?”

My favorite afternoon pick-me-up: purple sweet potato, peanut butter, and chocolate!

These Purple Sweet Potato Truffles are the result. They have a tender texture that sits somewhere between a chocolate truffle and a fudgy brownie, but they are packed with the antioxidants, nutrients, and fiber that make purple sweet potatoes a superfood!

Chocolatey and creamy, these truffles are perfect for dessert, snacking, or even a healthier sweet bite after dinner. If you’re looking for purple sweet potato recipes that are easy, unique, and downright delicious, this one deserves a spot in your kitchen.

What You’ll Need

3 ingredients needed to make these easy delicious truffles

Purple Potatoes: I used the Stokes variety for that intense purple hue.
Creamy Peanut Butter: Look for the all-natural kind where the only ingredient is peanuts!
Chocolate Chips: I love milk chocolate or semi-sweet chocolate for this recipe.

Optional: Extra melted chocolate and sea salt for coating.

That’s it. Simple pantry ingredients, big flavor payoff.

How to Make 3-Ingredient Purple Sweet Potato Truffles

1. Bake the Purple Sweet Potato

First, we need to get that sweet potato perfectly tender inside. Preheat your oven to 400°F. Rinse and cover your purple sweet potato with aluminum foil and bake for 45–60 minutes in the preheated oven. You’ll know it’s ready when it’s soft to the touch. Once cooled, peel away the skin and mash the vibrant flesh until it’s smooth.

2. Mix the Magic

Measure out 3/4 cup of your mashed potato into a bowl. Add in the 1/4 cup of peanut butter. Melt the chocolate chips (either in the microwave in short bursts or over a double boiler). Pour the melted chocolate into the sweet potato mixture and stir until everything is well-incorporated and looks like a thick, fudgy dough.

3. Roll and Chill

Form spoonfuls of the mixture into small balls. If you prefer, you could also form these into cookies. If you want to keep them simple, you can stop right here! Place them in the fridge to firm up for at least 30 minutes.

4. The “Savory Spin” Finishing Touch (Optional)

If you’re feeling extra, melt additional chocolate, dip each truffle to coat, and place them on parchment paper. If you made some cookie-shaped ones, these can be drizzled with chocolate or dunked in the melted chocolate. Return to the fridge and let the chocolate harden.

Sometimes I add a tiny sprinkle of flaky sea salt on top, which really makes that purple color pop!

Tips for the Best Truffles

Use natural peanut butter for the best texture
If your sweet potato is very moist, chill the mixture before rolling
For a firmer truffle, keep them refrigerated until serving

Shashi’s Expert Tip: If your sweet potato is extra fibrous, pass the mashed flesh through a fine-mesh sieve before mixing. This ensures your truffles have that ultra-silky, melt-in-your-mouth “cheesecake” texture!

Variations

Potatoes: To keep that purple hue, instead of a Stokes potato, an Okinawa Sweet potato could also be used. Alternatively, a Japanese Sweet Potato (with its creamy white flesh) or one of the orange varieties would work as well. These can be found at most grocery stores. However, I would not suggest using regular potatoes, such as red, Russet, or baking potatoes. These varieties are not sweet enough, and their texture is not as creamy as a sweet potato.
Peanut Butter: I prefer creamy PB for this recipe. However, if you want a bit more texture, then crunchy peanut butter could also be used. If you are avoiding sugar, use one with no added sugars. By the way, if you happen to like Peanut Butter & Co PB, you can use my code “SAVORY-SPIN” to get 10% OFF your entire online order at Peanut Butter & Co.
Chocolate Chips: Use dark chocolate or dairy-free chips to keep these vegan. And, as with the PB, sugar-free chocolate chips or a chopped chocolate bar could also be used. If opting for the latter, Trader Joe’s has some Dark Chocolate Bars that have only 5 grams of sugar (per serving) and melt beautifully.
Protein: A scoop of vanilla protein powder or flavorless collagen can be added to these truffles (just like I did with these collagen cookies) to amp up their protein content.

Storage and Serving

Because these are made with real, whole foods, they are best kept in an airtight container in the refrigerator. They’ll stay fresh for 3-4 days—though in my house, they rarely last more than two days! Unfortunately, these do not freeze well.
