There were four baked sweet potatoes in my fridge and a nine-year-old at my elbow asking for a fudge pop.
We were out of fudge pops.
What I had was chocolate, milk, cream, and a stubborn refusal to drive to the store on a Sunday.
So I threw a sweet potato into the blender with the rest of it, mostly as a joke.
It was not a joke.
Sweet potato does something to a chocolate popsicle that I did not expect.
It doesn't taste like sweet potato at all.
It just makes the whole thing thicker, denser, and creamier, the way a store-bought fudgesicle is creamy without ever being ice cream.
All that starch and moisture sits between the ice crystals and keeps them small.
Real melted chocolate does the rest.
My kids have no idea there's a vegetable in these and I have no plans to tell them.
They freeze in about five hours and a batch makes six.
Six is never enough, so I've started doubling it and filling a second set of molds while the first is still going in.
What You Need for Sweet Potato Fudgesicles
Eight ingredients, and the chocolate is the one to spend money on. Everything else is pantry standard.
- Cooked mashed sweet potato (1 cup). Roasted or boiled, peeled, and mashed. It needs to be cool before it goes in the blender.
- Whole milk (¾ cup). Skim milk freezes hard and icy. Fat is what keeps a popsicle soft enough to bite.
- Heavy cream (½ cup). This is the difference between a fudgesicle and a frozen chocolate milk.
- Dark chocolate (4 oz, chopped). Something in the 60 to 70 percent range. Chocolate chips are formulated to hold their shape, so they melt thick and waxy. Use a bar.
- Cocoa powder (2 tablespoons). Unsweetened. It deepens the color and adds a slight bitterness that keeps the pops from tasting like candy.
- Brown sugar (3 tablespoons). Dissolves cleanly into the warm milk and adds a caramel edge.
- Vanilla extract (½ teaspoon). Added off the heat.
- Salt (a pinch). Small amount, big job. It makes the chocolate taste more like chocolate.
How to Make Sweet Potato Fudgesicles
You warm the dairy, melt the chocolate into it, then blend everything with the sweet potato. The blender is doing the important work here.
Step 1: Cook the Sweet Potato
Roast a whole sweet potato at 400°F for 45 to 55 minutes, or peel, cube, and boil it for 15 minutes until fork-tender.
Roasting gives you more flavor and less water. Boiling is faster.
Cool it completely, then measure out 1 cup of mash.
Step 2: Warm the Dairy and Melt the Chocolate
Heat the whole milk, heavy cream, and brown sugar in a small saucepan over medium-low heat, whisking until the sugar dissolves.
Pull it off the heat right before it simmers. You want it warming, not bubbling.
Add the chopped chocolate and let it sit undisturbed for 2 minutes, then whisk until it's glossy and completely smooth.
Step 3: Blend Until Silky
Pour the chocolate mixture into a blender with the mashed sweet potato, cocoa powder, vanilla, and salt.
Blend on high for a full 60 seconds.
Longer than you think is necessary. Any fiber you leave behind shows up as a gritty bit on the tongue later.
Pro tip: stop and scrape the sides once at the 30-second mark. Sweet potato likes to climb the walls of the jar and hide.
Step 4: Fill the Molds
Let the mixture cool to room temperature before it goes into the molds.
Pouring it in warm will crack a plastic mold and it slows the freeze enough to grow bigger ice crystals.
Fill each cavity to about ¼ inch below the rim, since the mixture expands.
Tap the mold firmly on the counter a few times to knock out air pockets, then insert the sticks.
Step 5: Freeze
Freeze for at least 5 hours, or overnight for a clean release.
To unmold, run warm tap water over the outside of the mold for 15 to 20 seconds and pull the stick straight up with steady pressure.
Don't wiggle it. Wiggling snaps sticks.
Tips for the Creamiest Texture
Icy popsicles are a water problem, not a recipe problem. Every tip below is about keeping water from organizing itself into crystals.
- Use full-fat dairy. Whole milk and heavy cream, no substitutions. Fat physically blocks ice crystals from growing large.
- Blend a full minute. Under-blended sweet potato leaves fiber, and fiber holds water in pockets that freeze hard.
- Don't skip the melted chocolate. Cocoa powder alone gives you a light, ice-milk texture. Real chocolate brings cocoa butter, and cocoa butter is what makes it fudgy.
- Cool before freezing. A warm mixture takes longer to freeze, and slow freezing means bigger crystals. Every time.
- Freeze fast and cold. Back of the freezer, not the door. Clear a shelf so cold air can circulate around the mold.
- Add a tablespoon of corn syrup. This is my one optional trick. It interferes with crystal formation and keeps the pops soft for weeks instead of days.
Variations
- Milk chocolate version. Swap the dark chocolate for milk chocolate and cut the brown sugar to 1 tablespoon. Milk chocolate brings its own sugar to the party.
- Peanut butter swirl. Warm 3 tablespoons of creamy peanut butter until it's pourable, then spoon it into each mold in two or three additions as you fill. Drag a skewer through once.
- Maple instead of brown sugar. Use 3 tablespoons of real maple syrup. It leans a little more autumnal.
- A spoonful of molasses. 1 teaspoon adds a deep, almost smoky caramel note underneath the chocolate.
- Espresso fudgesicle. ½ teaspoon of instant espresso powder dissolved into the warm milk. It doesn't taste like coffee, it just makes the chocolate louder.
- Cinnamon chocolate. ½ teaspoon of cinnamon and a tiny pinch of cayenne, for the Mexican hot chocolate angle.
Storage
- In the molds. Fine for up to 3 days if you're going to eat them that fast, and it's the easiest option.
- Longer storage. Unmold them, wrap each pop individually in parchment or plastic, and stash them in a zip-top freezer bag.
- How long they stay good. Best within 2 weeks. They stay safe well past that, but the texture slowly turns and they start absorbing whatever else lives in your freezer.
- The one thing to avoid. Don't leave them uncovered in the freezer. Uncovered chocolate picks up freezer odors faster than almost anything else.
Frequently Asked Questions
How do you make sweet potato ice pops?
Blend cooked, cooled sweet potato with a liquid base until fully smooth, sweeten it, pour it into popsicle molds, insert sticks, and freeze for 5 hours or more. For a fudgesicle you use whole milk, heavy cream, and melted chocolate as that base. For a lighter fruit-style pop you could use milk and honey with cinnamon instead. The technique is the same either way: blend longer than feels necessary, cool before freezing, and freeze fast.
Is it better to freeze sweet potatoes raw or cooked?
Cooked, without question. Raw sweet potato freezes badly, discolors, and turns mealy when it thaws. Cooked and mashed sweet potato freezes beautifully for 3 months and is exactly what you want on hand for a recipe like this. I portion leftover mash into 1-cup containers specifically so a batch of these is always twenty minutes away.
Can I use canned sweet potato puree instead of cooking my own?
Yes. Use plain unsweetened puree, not canned pie filling, and drain off any liquid sitting on top. The flavor is slightly flatter than roasted, but with this much chocolate in the mix you honestly won't notice.
How long do sweet potato fudgesicles keep in the freezer?
About 2 weeks at their best. Wrap them individually once they're unmolded and keep them in a sealed bag. Past two weeks they're still edible, but ice crystals start creeping in and the fudgy texture goes.
Can I make these without popsicle molds?
You can. Small paper cups work well: fill them, cover each with foil, poke a stick through the center of the foil so it stands upright, and freeze. Peel the cup off to serve. An ice cube tray with toothpicks makes bite-size ones for little kids. A small loaf pan works too, and you scoop it like a soft fudge instead.
Why did my fudgesicles come out icy instead of creamy?
Almost always one of three things: low-fat dairy instead of whole milk and cream, an under-blended sweet potato leaving fiber and water pockets, or a warm mixture poured into the molds and frozen slowly. Fix all three and the texture changes completely. Skipping the melted chocolate in favor of cocoa powder alone will do it too, since cocoa butter is a big part of what makes a fudgesicle fudgy.
Can I swap dark chocolate for milk chocolate?
Yes, and my kids prefer it that way. Cut the brown sugar down to 1 tablespoon, because milk chocolate is already sweetened. Keep the cocoa powder, since that bitterness is what stops the pops from tasting like a frozen candy bar.
Recipe
Sweet Potato Fudgesicles
Ingredients
For the Fudgesicles
- 1 cup cooked sweet potato peeled, mashed, and cooled
- ¾ cup whole milk
- ½ cup heavy cream
- 4 oz dark chocolate 60 to 70 percent, chopped from a bar
- 2 tablespoons unsweetened cocoa powder
- 3 tablespoons brown sugar packed
- ½ teaspoon vanilla extract
- 1 pinch salt
Instructions
Cook the Sweet Potato
- Roast a whole sweet potato at 400F for 45 to 55 minutes until completely tender, or peel, cube, and boil for 15 minutes until fork-tender.
- Cool completely, then peel and mash. Measure out 1 cup.
Make the Chocolate Base
- Heat the whole milk, heavy cream, and brown sugar in a small saucepan over medium-low heat, whisking until the sugar dissolves. Remove from the heat just before it simmers.
- Add the chopped chocolate, let it sit undisturbed for 2 minutes, then whisk until glossy and smooth.
- Pour the chocolate mixture into a blender with the mashed sweet potato, cocoa powder, vanilla, and salt. Blend on high for a full 60 seconds, scraping the sides once at the halfway point.
Fill and Freeze
- Let the mixture cool to room temperature. Fill each popsicle mold cavity to about ¼ inch below the rim.
- Tap the mold firmly on the counter several times to release air pockets, then insert the sticks.
- Freeze at least 5 hours or overnight. To unmold, run warm tap water over the outside of the mold for 15 to 20 seconds and pull each stick straight up without wiggling.
Notes
- Freeze time: At least 5 hours, or overnight for the cleanest release. This is on top of the listed prep and cook time.
- Use a chocolate bar: Chocolate chips are formulated to hold their shape and melt thick and waxy. A chopped bar melts smooth.
- Full-fat dairy only: Skim or low-fat milk will make the pops icy. Fat is what keeps the texture fudgy.
- Anti-ice trick: Add 1 tablespoon of corn syrup to the blender to keep the pops soft for weeks instead of days.
- Storage: Best within 2 weeks. Unmold, wrap each pop individually, and keep them in a sealed freezer bag so they do not pick up freezer odors.
