Sugar-free hazelnut chocolate truffles are a rolled, no-bake dessert made from a dark chocolate and cream ganache folded with ground toasted hazelnuts, sweetened with erythritol instead of sugar.
I started making these when my sister went low-carb and missed her holiday truffle box. The ganache sets in the fridge in about 2 hours, then you roll it into balls and coat them in more chopped hazelnuts or cocoa powder.
They taste rich and a little nutty, with a soft center firm enough to hold its shape at room temperature for maybe 20 minutes before it starts to soften. That’s the thing to watch for. If your kitchen runs warm, keep the tray chilled until you’re ready to serve.
No candy thermometer, no baking. Just a saucepan, a bowl, and patience while the ganache firms up.

Ingredient Notes
- hazelnuts: Toast them yourself for the best flavor. Pre-toasted hazelnuts work in a pinch but taste flatter.
- sugar-free dark chocolate: Look for 85% or higher cacao sweetened with erythritol or monk fruit. Regular sugar-free chocolate chips melt grainier, so bar chocolate works better here.
- powdered erythritol: Monk fruit blend works as a 1:1 swap. Granulated erythritol can taste gritty in the ganache, so use the powdered form if you can find it.
- heavy cream: Full-fat cream gives the ganache its smooth set. Half and half will make a softer, stickier truffle that’s harder to roll.
- unsweetened cocoa powder: Use natural cocoa, not Dutch-process, for a slightly deeper, more bitter coating that balances the sweetener.
Sugar-Free Chocolate Truffles with Toasted Hazelnuts
Ingredients
Method
- Toast whole hazelnuts in a dry 10-inch skillet over medium heat for 4 to 5 minutes, tossing often, until fragrant and the skins crack and blister.
- Rub the warm hazelnuts in a clean kitchen towel to remove most of the skins. Let cool completely.
- Pulse 100 g of the cooled hazelnuts in a food processor until finely ground, almost like coarse sand. Finely chop the remaining 50 g by hand and set aside for coating.
- Heat the heavy cream in a 1-quart saucepan over medium-low heat until steaming, about 80 C / 175 F, 3 to 4 minutes. Do not let it boil.
- Remove from heat, add the chopped sugar-free chocolate, and let it sit for 2 minutes to soften.
- Whisk until the ganache is smooth and glossy. Whisk in the butter, erythritol, vanilla, and salt until fully melted and combined.
- Fold in the ground hazelnuts until evenly distributed through the ganache.
- Cover the bowl and chill for 2 hours, until the ganache holds a dent when pressed with a spoon and no longer looks glossy and loose.
- Scoop tablespoon portions, about 25 to 27 g each, and roll into balls between your palms, working in small batches so the mix stays cold.
- Roll each ball in the chopped hazelnuts or cocoa powder to coat, then place on a parchment-lined sheet pan.
- Chill the coated truffles for 20 minutes more before serving, or transfer to a container for storage.
Notes
- Use bar chocolate, not chips, for a smoother ganache texture.
- Chill the bowl again if the mixture sticks to your palms while rolling.
- Toast hazelnuts in one batch, then split for filling and coating.
- Store rolled truffles between parchment layers to protect the coating.
Tips for Success
- Toast the hazelnuts until the skins crack and blister, about 4 to 5 minutes, for the deepest flavor.
- Chill the ganache at least 2 hours before rolling, it should hold a dent when pressed with a spoon.
- Wet your palms slightly with cold water if the mixture keeps sticking while you roll.
- Work in small batches of 5 to 6 truffles at a time, popping the bowl back in the fridge if it softens.
- Chop the coating hazelnuts fine and even, so each truffle gets a consistent crunchy shell.
Variations
- Swap half the ground hazelnuts for almond flour for a lighter, less nutty center.
- Roll finished truffles in unsweetened shredded coconut instead of cocoa for a different texture.
- Add 1/4 tsp espresso powder to the ganache for a mocha edge that plays well with the hazelnuts.
Storage and Reheating
Sugar-free hazelnut chocolate truffles keep in an airtight container in the fridge for 10 to 14 days. Layer them between sheets of parchment so the coating doesn’t smudge.
For longer storage, freeze the rolled truffles on a tray until solid, then transfer to a freezer bag for up to 2 months. Thaw in the fridge for 2 to 3 hours before serving.
These are a fridge dessert, not a reheated one. Let them sit at room temperature for 5 to 10 minutes before eating so the center softens slightly.
Serving Suggestions
Set sugar-free hazelnut chocolate truffles out on a small plate with espresso or unsweetened coffee. The bitterness of the coffee balances the richness of the ganache.
They work well on a holiday dessert board next to fresh berries and a wedge of hard cheese. The tartness of berries cuts through the fat nicely.
For gifting, pack 6 to 8 truffles in a small tin lined with parchment. Keep the tin refrigerated until an hour before handing it over.
FAQ
Why are my hazelnut chocolate truffles too soft to roll?
The ganache probably hasn’t chilled long enough. It needs about 2 hours in the fridge until it holds a dent when you press a spoon into it. Warm kitchens slow this down, so give it another 20 to 30 minutes and check again before rolling.
Can I use almond flour instead of ground hazelnuts?
Yes, you can swap in an equal amount of almond flour, though the flavor turns milder and less nutty. I still like using at least half hazelnuts so the toasted flavor comes through. Keep the coating hazelnuts as is for the best crunch.
How long do sugar-free hazelnut chocolate truffles last in the fridge?
They keep well for 10 to 14 days in an airtight container in the fridge. Layer parchment between rows so the cocoa or hazelnut coating doesn’t rub off. For longer storage, freeze them for up to 2 months.
What goes well with sugar-free hazelnut chocolate truffles on a dessert board?
Fresh berries, unsweetened coffee, and a hard cheese like aged gouda all pair well. The tartness in berries and the bitterness in coffee cut through the richness of the ganache. A small glass of dry red wine works too if you’re serving these after dinner.
Are these hazelnut chocolate truffles keto friendly?
Yes, with roughly 9g of carbs and 4g of fiber per serving of two truffles, they fit most keto carb limits. The sweetener is erythritol, which doesn’t spike blood sugar the way regular sugar does. Check your chocolate label since brands vary slightly in carb count.
What’s the difference between these and classic Ferrero Rocher style truffles?
Ferrero Rocher uses a wafer shell and a whole hazelnut center with milk chocolate and sugar. This version skips the wafer and sugar entirely, using a dark chocolate ganache folded with ground hazelnuts instead. The result is denser and less sweet, with a stronger cocoa flavor.
