This sugar-free low carb chocolate mousse it’s no exception since it’s chocolatey, light, and airy just like my sugar-free chocolate pudding.

I love to add some berries and mint leaves when they are in season for extra taste and freshness. It’s perfect to be used as a keto cupcakes frosting or inside some delicious layers of low carb cake.

Surprise your guests with a decadent chocolate dessert and I guarantee you that everyone will be delighted. Here are the main ingredients you’ll need:

  • Cocoa Powder: Choose a really good cocoa powder for the best chocolate taste. Dutch-process cocoa powder is the best kind because it makes the chocolate flavor even richer.
  • Heavy Cream: If you can’t have dairy or just want to try something different, you can use coconut milk instead of heavy cream. It still works great and makes the dessert creamy.
  • Sweetener: You can pick your favorite sugar-free sweetener to make the mousse sweet. Xylitol*, erythritol, or monk fruit are all good choices. Just use what you like best!
  • Gelatin Powder: This helps make the mousse thick and fluffy. Just mix it with cold water and make sure not to cook it too much so it works right.
  • Cold Water: This is for mixing with the gelatin powder to help it dissolve before you add it to the mousse.
  • Dark Chocolate: Melting some dark chocolate and adding it to your mousse makes it extra chocolatey and rich. Pick a chocolate you really like to eat.
  • Vanilla Extract: A little bit of vanilla makes everything taste better. It goes really well with the chocolate and makes the mousse taste even more special.

*Xylitol is extremely toxic to dogs, so if you’re a dog lover, be very careful when using it.

Flavor Variations

Here are my favorite flavor variations for keto chocolate mousse:

  • Mint: Add 1/2 tsp drops of peppermint extract along with the vanilla extract.
  • Raspberry: Stir in some fresh or frozen raspberries for a fruity and tangy flavor.
  • Hazelnut: Add some hazelnut butter or hazelnut extract for a nutty and rich flavor.
  • Coffee Chocolate: Dissolve 1 teaspoon of instant coffee or espresso powder in the melted chocolate before adding it to the mixture. This will give your mousse a rich coffee flavor that coffee lovers will adore.
  • Coconut: Use coconut milk in place of heavy cream and add 1/2 cup of toasted shredded coconut into the mix for a tropical coconut chocolate version. Garnish with additional toasted coconut.
  • Spicy: Add a pinch of cayenne pepper and 1/2 teaspoon of cinnamon to the cocoa powder for a mousse with a warm, spicy kick. This variation is inspired by traditional Mexican chocolate.

A Few Tips For Success

  • Use high-quality ingredients to make a perfectly rich and creamy sugar-free chocolate mousse.
  • It’s important to allow enough time for the mousse to set completely in the fridge. Chill the mousse in the refrigerator for at least 2 hours. This will help it become firm and creamy.
  • An electric mixer or stand mixer will ensure the mousse mixture is smooth and fluffy.

  • Prepare the gelatin in a small bowl. Add the gelatin powder and mix it with the cold water. Let the mixture bloom for about 5 minutes, then microwave the mixture for 15-20 seconds until the gelatin is completely dissolved. Ensure not to overheat the gelatin to avoid destroying it.
  • Add the whipping cream and vanilla extract. Beat the mixture at medium speed with a mixer until the mixture looks fluffy and forms stiff peaks.
  • Add the slightly cooled melted chocolate, the gelatin mixture, sweetener, and cocoa powder. Mix again at a low to medium speed until all the ingredients are fully incorporated and the mixture is uniform in color.
  • Divide the mousse evenly among serving glasses. Place the serving glasses in the refrigerator for at least 30 minutes to allow the mousse to set. For the best flavor and texture, let the chocolate mousse chill overnight in the refrigerator.
  • If desired, top each serving with additional whipped cream (ensure you prepare extra whipped cream).



* Use canned coconut milk solids instead of the heavy whipping cream for a dairy-free chocolate mousse.
Serve topped with a dollop of whipped cream, fresh raspberries or strawberries, a sprinkle of sea salt or chili powder, or garnish with chopped nuts or cacao nibs. Serving with espresso or dessert wine like Port turns it into an extraordinary treat.
