How to make easy keto chocolate mousse

Many chocolate mousse recipes require a lot of work, melting the chocolate chips, separating the egg whites, and making sure they don’t scramble in the hot chocolate. Who has time for that? I sure don’t! So, I decided to make a quick, sugar-free mousse that is super simple and low carb. This step-by-step recipe tutorial is going to show you how!

Main ingredients you’ll need to make keto chocolate mousse:

  • Heavy Whipping Cream – The heavy whipping cream is the base of this keto dessert providing a fluffy texture while adding extra fat.
  • Cocoa Powder – Is the unsweetened product of the cocoa bean; it adds a deep, rich chocolate flavor and a dark color to your dessert.
  • Besti Monk Fruit Sweetener with Allulose Powdered – This sweetener provides the perfect amount of sweetness without the aftertaste. (You can also sub Swerve Confectioners or Lakanto Monkfruit Powdered)
  • Butter and cream cheese – These ingredients provide a rich and super creamy texture.
  • Vanilla extract- This makes everything taste better.

Heavy whipping cream beaten in a glass bowl.

Step 1: Add heavy whipping cream to a mixing bowl and beat with a hand mixer or stand mixer until you see stiff peaks form; it takes approximately 1 minute. Make sure not to over-beat, or you will be left with a dense and heavy texture.

Before adding your cream to the bowl, it is important that the cream and bowl have both been chilled. A cold bowl and cold cream are the tricks for stiff, fluffy peaks! Also, make sure that your bowl and beaters are completely dry.

Step 2: In a separate bowl, add the rest of the ingredients and beat on medium speed. Sometimes cocoa powder clumps together; if needed, you can sift it before. Whip it until a thick chocolate paste forms. 

I would suggest using a larger bowl when beating the cocoa mixture so that it doesn’t get everywhere when you mix it.

Step 3: Combine your whipped cream and chocolate mixture and beat until light and billowy.

Step 4: Grease your ramekins, or 8X8 pan, and pipe or scoop a layer of keto chocolate mousse on the bottom. Make the second layer of delicious homemade sugar-free whipped cream by beating heavy whipping cream, and sweetener. Add that to the top of your mousse, and if desired, shave some unsweetened dark chocolate over the top for a tasty and pretty garnish. Enjoy!

Is chocolate mousse keto-friendly?

Yes! As long as you use a natural sweetener like one of the ones listed below. The fact that it is high in fat and low in carbs makes it completely keto-approved.

How to store low carb chocolate mousse

You can store your mousse in an airtight container in the fridge for up to a week. It can also be frozen for up to 2 months. However, since this keto mousse contains cream cheese, the texture may be slightly altered in the process of freezing and defrosting.

I like to add them to mini mason jars with a lid, so they are easy to grab and perfectly portioned out.

Total net carbs per serving

There are 3g of carbs per serving and 1g of fiber. Meaning there are only 2g net carbs per serving in this keto chocolate mousse recipe. I divide it into six equal-sized servings. Also, the heavy whipping cream, butter, and cream cheese add 25g of fat, making this keto dessert the perfect sweet fat bomb.

Can I use other sweeteners?

Yes, you can! Some great alternatives are Swerve Confectioners, and Lakanto Monk Fruit Powdered, both have a 1:1 ratio with the sweetener I use. However, I recommend using Besti Monk Fruit with Allulose powdered. Out of all the sweeteners that I have tried, this one has the least amount of after taste.

Unlike other keto sweeteners, this one contains Allulose, which is a natural sugar that our bodies can’t process. Coincidentally, it has zero net carbs, and a zero glycemic effect. Meaning it won’t raise blood sugars.

Allulose also dissolves like sugar, while other keto sweeteners do not. Lastly, allulose does not contain sugar alcohol, so it is not likely to upset your stomach.

Stevia is another option, but it tastes bitter to me. If you wish to use this, here is a conversion calculator you can use!

Low carb toppings for your mousse

  • keto-friendly fresh fruit – Fresh fruit such as strawberries and raspberries take this recipe over the top. It adds an extra tang to the decadent chocolate flavor.
  • Unsweetened chocolate shavings – What is more comforting than chocolate? I’m a firm believer that it makes everything better! So, adding a little extra makes this keto dessert so amazing!

    Mine was lumpy too, was using a hand mixer, had cocoa powder everywhere! Too dry, I added some heavy cream to it, to moisten it just a bit and then it worked. Seems like there isn’t enough wet with the cocoa mix.

    1. I’m sorry that it was lumpy for you. I’ve never had that experience. It sounds like you worked it out.

  2. I just put it all in a mixer at once let the mixer do its work! So good with 1/2 the trouble.

    BEST MOUSSE RECIPE EVER! I would make this over any non keto recipe ANY DAY! Mine came out perfect just as the recipe was posted!
    Now how to pace myself and not eat an entire mason jar of it at once… baby steps ๐Ÿ˜Š
    Thank you for sharing this amazing dessert – especially to the keto newbies like me who canโ€™t live without chocolate ๐Ÿ‘

    1. Hi Stacy,

      Thank you so much for your kind feedback and 5-star rating. I am so glad you loved it.

    1. Hey Beck, I usually grease the ramekins because I have found that the mousse does not stick as much, and the ramekins are easier to wash. Not a necessary step that affects the recipe. Hope you enjoy it!
