The Best Keto chocolate mousse recipe

You might recall that I’ve already shared a couple of incredible keto no bake dessert recipes- like ice cream and a simple chocolate pudding, but none have been as easy as this low carb chocolate mousse.

This is the kind of dessert you can make when you are entertaining and are short on time OR when you just want a simple chocolate fix.

It comes together will very little prep and you can make it ahead of time if you like.

This sugar free and gluten-free chocolate mousse recipe has less than 2 grams of carbs per serving and NO sugar!

Oh, and if you like a mousse-like dessert, try my peanut butter mousse and strawberry mousse. Both are low in carbs but just as easy!

Ingredients you’ll need

Cream, chocolate, and vanilla extract: that is it! You’ve probably got everything in your pantry/kitchen already, but let’s break each one down to make things easier for you:

  • Heavy cream. Also known as double cream or thickened cream. For the best results, let your cream sit at room temperature. 
  • Chocolate. Any sugar free chocolate can work. I prefer sugar free chocolate chips, as I like my mousse to be sweet. However, if you prefer an ultra rich and dark mousse, use a keto chocolate bar that has at least 78% cocoa content (like Lindt chocolate). 
  • Vanilla Extract. A must for any good keto mousse!

How to make a low carb chocolate mousse

Making this homemade chocolate mousse is so quick and easy, and doesn’t require any fancy kitchen gadgets or equipment. I recommend prepping all your ingredients and utensils required first, then make it. 

Step 1- Heat the cream

Start by heating half your cream in a small saucepan, on low heat. The other half of the cream will be added in later. I like using a non-stick saucepan because the cream never scorches and it cooks everything evenly. Once it simmers, remove from the heat.

Step 2- Melt the chocolate

Next, place your chocolate into a large mixing bowl. You want your mixing bowl to be on the larger side because this is what we will mix everything in. Pour your warm cream over the top and let it sit for 1-2 minutes. This will allow the cream to melt the chocolate chips. After a few minutes, you can gently whisk it all together until smooth and glossy.

Now, you’ll want to add the remaining cream and the vanilla extract and gently fold it through. 

Step 3- Chill and blend

Finally, cover the bowl and refrigerate it for 2-3 hours. When it’s done, remove the mousse from the fridge and, using an electric hand mixer, whip the mousse until stiff peaks form. 

Once the keto mousse is stable and firm, it is ready to enjoy. Distribute the mousse amongst eight 6-inch ramekins or simply scoop it out into bowls. Top it with some keto whipped cream or drizzle it with some sugar free chocolate syrup

This recipe makes 8 heaping 1/4 cup servings.

Tips for success

  • You can prepare the mousse for up to 3 days in advance. You can keep in the mixing bowl during this time.
  • Allow your cream to reach room temperature, before heating in the saucepan. This avoids the sides of the pan burning because of the cold cream.
  • When beating the chilled mousse, stop as soon as stiff peaks form. Any more and the mousse will be too fluffy and will sink once transferred to bowls. 
  • Spread the chocolate mousse over some brownies, for a decadent dessert idea. 

Flavor Variations

While this mousse tastes incredible on its own, here are some fun flavor variations for you to try!

  • Espresso: Add 1/2 teaspoon espresso powder to the mousse.
  • Peppermint: Fold through 1/4 teaspoon peppermint extract. 
  • Orange Chocolate: Add orange zest and orange extract to the mousse, and serve with candied citrus peel. 
  • Coconut: Serve the mousse with coconut whipped cream, toasted coconut flakes and shredded coconut. 
  • Strawberry: Fold through 1/4 cup sliced strawberries into the mousse (pre-blending) and top with sliced strawberries on top.

Frequently Asked Questions

Does chocolate mousse have carbs?

This low carb chocolate mousse has just 2 grams net carbs per serving! This is easily one of the lowest carb mousse recipes you’ll ever find.

If you’d like another similar low carb dessert, try the chocolate avocado mousse which also has 2 grams of carbs or a peanut butter mousse, which has 3 grams of carbs.

Is double cream keto? 

Double cream, heavy cream, and thickened cream are all keto friendly. They are primarily made of fat with small amounts of protein and very negligible amounts of carbs. 

Low fat and reduced fat cream are higher in carbs, as they often compensate for the lack of fat with extra thickeners and sugar. 

Can I make this dairy free? 

Yes, this chocolate mousse can easily be dairy free, with a few simple swaps. 

Instead of the heavy cream, use a plant based double cream. For the chocolate chips, use dairy free chocolate chips or chunks. I prefer the Enjoy Life brand of them.

How many calories in this mousse?

There are around 200 calories per serving.

  1. Hiya! Love this site!! I’m a bit confused about chocolate mousse recipe?
    It says 8 servings.Than it says place in four bowls. Then nutrition is per serving! So I take it one serving is 1/2 a bowl am I right??
    Thanks for all the hard work of mastering these recipes.
    P.s. You’re awfully cute,!

    1. I forgot how long I’d left this in the fridge and it was too set to whip. But 4 servings disappeared within seconds! Had to stop my partner scraping the bowl.
      Great recipe even if I didn’t complete it.

  2. I’ve never heard of plant-based double cream. Where can we get that? Can you get it at like a Walmart or do you have to go to a specialty store?

  3. This is excellent!! Has no fake sugar flavor. Texture very smoothe. My husb loved it…while it lasted!

  4. The recipe calls for 1 cup chocolate. Do that mean 8 oz or something else. I don’t understand how a bar of chocolate could fit into a cup,

  5. Hi,

  6. I forgot how long I’d left this in the fridge and it was too set to whip. But 4 servings disappeared within seconds! Had to stop my partner scraping the bowl.
