Keto Chocolate Truffles (3 Ingredients)
These keto chocolate truffles are made with just three ingredients: Groovy Keto Dark Chocolate Buttons, double cream and cocoa powder. Each truffle has 0.6g net carbs and 79 kcal. It takes about 35 minutes of hands-on time, plus at least 3 hours in the fridge.
Chocolate truffles are one of the simplest homemade sweets: a ganache of chocolate and hot cream, chilled, rolled into balls and dusted with cocoa. BBC Good Food's easy chocolate truffles are a much-loved version of that classic method. Spinach Tiger's keto chocolate truffles show that it works just as well with low-carb chocolate and only three ingredients, and a keto chocolate truffles post on r/ketorecipes uses a similar chocolate-to-cream ratio with a cocoa coating. Our version keeps that simple method, uses 150ml of UK double cream, and swaps the chocolate for Groovy Keto Dark Chocolate Buttons, so there is no extra sweetener to add.
The result is a batch of 20 soft, rich keto chocolate truffles with 0.2g sugars each. They are easy to make ahead and box up as a Christmas gift. If you want something you can cut into squares, try our keto fudge; for more festive ideas, see our keto Christmas guide.

View productTips for smooth keto truffles
- Don't boil the cream. Take it off the heat as soon as it steams and bubbles at the edge. Cream that is too hot can make the ganache split or turn grainy.
- Leave it, then stir gently. Three minutes undisturbed lets the hot cream melt the buttons. Slow stirring from the centre outwards gives a smooth, glossy ganache.
- Chill it properly. The ganache needs at least 3 hours to firm up. If it is too soft to roll, put it back in the fridge for another 30 minutes.
- Keep your hands cool. Run your hands under cold water and dry them before rolling. Warm hands melt the outside and make the truffles sticky.
- Coat straight away. Roll each truffle in cocoa powder as soon as it is shaped, while the surface is still slightly tacky, so the coating sticks.

- Net carbs0.6g per truffle
Ingredients
- 200g Groovy Keto Dark Chocolate Buttons
- 150ml double cream
- 2 tbsp (15g) cocoa powder, for rolling
You will also need a heatproof bowl, a small saucepan, a spatula, a teaspoon or small melon baller and some baking paper.
Allergens: contains milk (cream). See the allergen notes under Nutrition.
Method
- Get the chocolate ready. Put the chocolate buttons in a medium heatproof bowl. If you have time, roughly chop them so they melt faster and more evenly.
- Heat the cream. Warm the double cream in a small saucepan over a medium heat until small bubbles appear around the edge and it is steaming. Take it off the heat before it boils.
- Make the ganache. Pour the hot cream over the buttons and leave for 3 minutes without stirring. Then stir slowly from the centre outwards until the ganache is smooth and glossy.
- Chill. Cover the bowl and chill for at least 3 hours, or overnight, until the ganache is firm enough to scoop.
- Shape. Scoop the ganache into 20 equal portions with a teaspoon or small melon baller, then roll each one quickly between cool hands into a ball.
- Roll in cocoa. Tip the cocoa powder onto a plate and roll the truffles in it until coated. Chill for 15 minutes on baking paper before serving or boxing.
Ways to change it
- Orange: stir the finely grated zest of 1 orange into the warm ganache.
- Mocha: dissolve 1 tsp instant coffee in the hot cream before you pour it over the buttons.
- Hazelnut: roll the truffles in 30g finely chopped toasted hazelnuts instead of cocoa. This adds nuts as an allergen.
- Coconut: roll them in desiccated coconut for a snowball look.
Each of these changes the nutrition figures slightly, so the table below is for the plain recipe.

What is a chocolate truffle?
A chocolate truffle is a small ball of ganache, which is chocolate melted into hot cream, rolled in cocoa powder or another coating. The name comes from the dusty, rough look of the cocoa coating, which resembles the prized truffle fungus. Because ganache is simply chocolate and cream, the chocolate you choose decides most of the carbs. For tips on melting chocolate without it seizing, read how to melt chocolate.

Net carbs are carbohydrate minus polyols. On UK labels, fibre is already listed separately from carbohydrate, so it isn't subtracted again. Our guide to what polyols are explains how they appear on UK labels. Figures are estimates calculated from the Groovy Keto Dark Chocolate Buttons pack label and UK (McCance and Widdowson's CoFID) data for double cream (12-334) and cocoa powder (12-545), with USDA data for the sodium in cocoa powder. They count all 15g of cocoa powder and will vary with the brands you use. Each truffle contains 3.0g polyols from erythritol. Excessive consumption may produce laxative effects.
Allergens: this recipe contains milk (cream). The Dark Chocolate Buttons pack says it is packed in a facility where there may be traces of nuts, cereals, milk and eggs. Always check the current pack labels, including your cocoa powder, before making it for anyone with an allergy.
FAQ
How many carbs are in a keto truffle?
Each of our keto chocolate truffles has 3.6g carbohydrate, of which 3.0g are polyols from the erythritol in the chocolate buttons, so it has 0.6g net carbs. It also has 79 kcal, 0.2g sugars and 1.8g fibre. The figures count all of the cocoa powder, even though some is left on the plate.
Why has my ganache split?
Ganache splits when the cream is too hot or the mixture is stirred too hard, and the fat separates out, so it looks oily or grainy. To bring it back, stir in 1 teaspoon of warm cream at a time, working from the centre outwards, until it turns smooth and glossy again.
How long do homemade truffles keep?
Keep refrigerated in an airtight container and eat within 3 days, with baking paper between the layers. Because they are made with fresh cream, keep them chilled. They taste best a little softer, so take them out about 10 minutes before you serve them.
What can I roll truffles in?
Cocoa powder is the classic coating and keeps these truffles to three ingredients. You can also roll them in finely chopped toasted hazelnuts, desiccated coconut or grated chocolate buttons. Roll them as soon as they are shaped, while the outside is still slightly sticky, and remember that nuts add an allergen.
Can you freeze chocolate truffles?
Yes. Freeze the rolled truffles on a tray until firm, then pack them into a freezer box with baking paper between the layers. Freeze for up to 1 month and defrost them in the fridge overnight. Give them a fresh roll in cocoa powder before serving if the coating looks damp.
