Chocolate mousse is a classic and timeless dessert that is perfect for any time of the year! Growing up, I used to buy the mini portion controlled ones, that would come in a pack of 4. As my tastebuds have matured, I’ve come to appreciate a good homemade version.

I’ve always been intimidated by making my own mousse, but it is so easy and simple to make. The best part was that it happened to naturally be low carb, but you’d never be able to tell. It’s just 3 simple ingredients, and you can make it as dark or sweet as you want!

How do you make chocolate mousse

The Ingredients

  • 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!

The Instructions

Start by heating up half your cream in a small saucepan, on low heat. Once it begins to simmer, remove from the heat. Place your chocolate into a large mixing bowl. Pour your warm cream over the top, and add the vanilla extract. Let it sit for 1-2 minutes, before gently whisking it all together, until smooth and combined. Add the remaining half of the cream and fold through. Cover the bowl and refrigerate for 2-3 hours. Remove from the refrigerator and using a stick mixer, whip the mousse until stiff peaks form. Distribute the mousse amongst 4 large bowls or 8 small ones, and serve.

Can I make this vegan? 

Yes, this chocolate mousse can easily be made vegan and 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. 

Tips for the perfect mousse

  • You can prepare the mousse for up to 3 days in advance. You can keep in the mixing bowl for
  • Allow your cream to reach room temperature, before heating up in the saucepan. This avoids the sides of the pan burning, due to 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

  • Espresso Chocolate Mousse– Add 1/2 teaspoon espresso powder to the mousse.
  • Peppermint Chocolate Mousse– Fold through 1/4 teaspoon peppermint extract. 
  • Orange Chocolate Mousse- Add orange zest and orange extract to the mousse, and serve with candied citrus peel. 
  • Coconut Mousse– Serve the mousse with coconut whipped cream, toasted coconut flakes and shredded coconut. 

Storing and Freezing Tips

  • To store: Mousse should always be stored in the refrigerator, completely covered, to ensure no moisture seeps in. The mousse will keep well for up to 2 weeks.
  • To freeze: You can freeze the chocolate mousse, by placing it in a freezer friendly container, for up to 6 months. Thaw the mousse overnight in the refrigerator.

    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,!

    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?
