My 5 ingredient chocolate mascarpone mousse satisfies your most urgent chocolate cravings. It is a creamy keto mascarpone dessert that you can make in only 10 minutes.

This mascarpone mousse recipe is quick and easy - and you would never guess it's sugar-free! With a dreamy chocolate and vanilla swirl, it is impressive enough to serve at a dinner party.
Mascarpone, an Italian soft cheese, is perfect for keto desserts. It has a high fat content, which makes it incredibly creamy. On top of that, it is low in carbs.
Popular keto mascarpone recipes on my website include this keto tiramisu, my strawberry mascarpone tart and these cocoa fat bombs.
This chocolate mascarpone mousse is a wonderful egg-free alternative to my classic sugar free chocolate mousse, which is made the "French way", with whipped egg whites.

The Inspiration

This recipe is inspired by this "duo of chocolate mousse", created by the famous chef Anton Mosimann. Check it out in the picture on the right - THAT kind of decoration you've got to leave to the experts!
Mosimann is a Swiss national, which is why I called this recipe "Swiss chocolate mascarpone mousse" when I first posted it in July 2018.
Naturally, you can use quality cocoa from anywhere in the world for this mousse. When I revised the post, I deleted the word "Swiss" to avoid confusion.
The recipe remains the same.
Ingredients
You only need 5 ingredients for this chocolate and mascarpone keto dessert (or 6, if you make the recipe exactly like I did):
- Mascarpone - I used fridge-cold mascarpone cheese.
- Heavy cream - This is also called double cream.
- Cocoa powder - Choose unsweetened cocoa powder.
- Powdered sweetener - I used an erythritol monk fruit blend when I first made this recipe, but you could also use Bocha Sweet, allulose or xylitol. Stevia drops will also work.
- Vanilla extract - We need this to flavor the vanilla mousse.
The sixth ingredient is cream cheese. I use it in place of the mascarpone for the vanilla mousse portion. I'll be honest with you - I had planned on using more mascarpone, but accidentally added chocolate to the whole lot.
Sometimes, having to wing it yields surprisingly positive results. I can report that mascarpone and cream cheese are interchangeable in this recipe. However, mascarpone, due to its higher fat content, stays firm when you whip it. Cream cheese softens when you blend it. (This is because cream cheese has half the fat of mascarpone.)
That's why the method for making the chocolate mousse and the vanilla one differs slightly:
Instructions

STEP 1
Put all ingredients for the chocolate mascarpone mousse in a large mixing bowl (mascarpone, cream, cocoa powder, sweetener). Blend with an electric mixer until well combined and the mixture thickens.
STEP 2
Now, whisk the whipping cream for the vanilla mousse in a second bowl to soft peaks. Add the cream cheese, vanilla extract and powdered sweetener last.

STEP 3
Fill the chocolate mousse into serving glasses and dollop the vanilla mousse on top. Swirl with a knife until you have a marble effect.
Serve straight away or refrigerate until serving.
Katrin's Top Tip
Stop blending the mousse as soon as it has a creamy consistency. Do not over-mix!
Variations
If you cannot source mascarpone, use cream cheese for the whole lot. Whip the cream separately to soft peaks and fold it in last.
You could also use ricotta cheese.
Possible add-ons to the chocolate mixture are 1 teaspoon coffee extract, ½ teaspoon orange extract or 1 teaspoon of cinnamon. Even a teaspoon of brandy would work well.

Recipe FAQs
Mascarpone tastes creamy and mild. It is slightly sweet and less tangy than Greek yogurt, quark or cream cheese.
For a dairy-free mousse, use a vegan mascarpone and coconut cream in place of the dairy cream. You can buy vegan mascarpone or make your own. There are many recipes online.
Storage
This keto mascarpone mousse recipe is very rich and makes 8 heavenly creamy portions. You can store leftovers in the fridge for up to 4 days. Cover the cups with clingfilm or store it in an airtight container.
I don't recommend freezing the mousse, because whipped cream is never the same when you defrost it.
However, you can freeze leftovers in ice cube trays or popsicle moulds and enjoy them frozen! Due to the high fat content, the mousse does not freeze solid. It turns into luscious ice cream.

I've just made this dessert for visiting guests today. Omg! 3 of us already here had a sneaky taste test and we thought we'd died and gone to heaven We're having a bbq but we want to skip it and go straight to dessert. Thank you
Pamela
Love this recipe but I wonder why there is no protein count in the nutrition list.
Katrin Nürnberger
Hi Pamela, I added the protein per serving. Thanks for pointing it out!
Ann Crump
So full of flavour. My non keto partner asked to have it again. Looks good too.
Liz
Easy and Decadent!!
My husband didn't believe that this was Keto friendly. I added chocolate shavings and strawberries and my Keto and Non Keto eaters enjoyed thoroughly!
The only thing I did differently is the sweetener. I do not have powdered on hand, so I used Monk Fruit sweetener. You can feel the texture of the sugar a little, but it doesn't bother me one bit.
Setting up as I type this to make another batch!

Omg this chocolate mousse is amazing!!!! The best I have ever eaten…
