Easy Keto Chocolate Mousse

Keto Chocolate Mousse is a 4-ingredient recipe that is made with such ease, your family and friends will absolutely love it! This low carb chocolate mousse is extra fluffy and whips up so quickly and will cure that chocolate craving any time of the day without any of the guilt!

Keto Chocolate Mousse

If you have seen our keto pumpkin mousse and loved it, then I’m even more excited to share with you this keto chocolate mousse. It’s so light and fluffy and what’s even better is that it only has 4 ingredients. Yup, that’s right, only 4 ingredients! 

I always thought that mousse was this fancy dessert that was too complicated to make. So I never really tried making it until recently and I found out how easy it is.

That being said, I figured: “Why not do chocolate mousse?” I mean, it’s chocolate…need I say more? So when looking for a low carb chocolate recipe this is the one to try.

What is Chocolate Mousse?

Mousse is a light and soft dessert that has air bubbles incorporated into it to give you an airy texture. Mousse can range from light and fluffy to thick and creamy depending on how it’s made or what ingredients are used. You can make a sweet or savory mousse. 

Chocolate mousse is typically made with whipped cream or whipped egg whites, then combined with cocoa powder or melted chocolate. After the chocolate mousse has been whipped, it is then chilled before being served. 

Chocolate mousse can either be served by itself, topped with whipped cream, or it can be used as a filling in a cake. 

Fun Fact: The word “mousse” means “foam” in French. So, I guess mousse is like eating foam then?

The Four Main Components of a Mousse

When making a mousse, including a keto chocolate mousse recipe, there are typically four main components it’s made out of. That doesn’t mean you can’t play around with it and add more or less, but these four components are what it’s primarily made from.  

  1. Base – Chocolate, Pumpkin, Salmon, Chicken Liver etc….
  2. Binder – Egg Whites or Gelatin. 
  3. Lightening Agent – Whipped Cream or Beaten Egg Whites. 
  4. Flavoring – Extracts for sweet mousse, or seasonings such as salt and pepper in a savory mousse.

What is the Difference Between Chocolate Mousse and Chocolate Pudding?

Keto Chocolate Fluff

Chocolate mousse and chocolate pudding are not quite the same thing, even though a lot of people get them confused with each other. 

Keto Chocolate Mousse is a light and airy dessert. The cocoa powder is mixed in with the heavy cream to give it a light texture. I think of this low carb chocolate mousse as being more like a thicker chocolate whipped cream. Unlike pudding, keto chocolate mousse is not cooked. 

Keto Chocolate Pudding is made by cooking the milk or cream and sugar and then adding a thickener to the mixture. Pudding can contain egg yolks, cornstarch, or xanthan gum to thicken it.

For something different, make sure to try our Keto Chocolate Pudding recipe which is equally as tasty!

What Is the Difference Between Mousse and Whipped Cream?

Whipped cream and mousse are very similar, considering that you whip heavy cream in both recipes. In typical mousse recipes, there are usually egg whites used to help bind the mousse together. 

On the other hand, whipped cream only has heavy cream, sweetener, and most of the time vanilla. 

Mousse recipes can have several different additions to them including pumpkin puree, extracts, and even fruit.

Is Chocolate Mousse Bad for You?

Relatively speaking this is a healthy chocolate mousse recipe. Considering it has a low carb sweetener and unsweetened cocoa powder it isn’t loaded down with sugar or any other hidden ingredients. 

The only ingredient that isn’t probably deemed as super healthy is the heavy cream. But when eaten sometimes instead of all the time it’s ok to eat! So go ahead and enjoy some low carb mousse.

How Many Calories are in Low Carb Chocolate Mousse?

How many calories are there in low carb chocolate mousse? Our recipe for a sugar-free chocolate mousse has 323 calories per serving. The recipe has 4 servings all together.

Other recipes for non-keto chocolate mousse can have as many as 400-500 calories per serving.

Is Mousse Keto-Friendly?

Easy Keto Chocolate Mousse

Chocolate mousse is totally keto-friendly! It’s made with heavy cream, unsweetened cocoa powder, low carb sweetener, and vanilla. All of these ingredients are 100% keto-friendly, making this the perfect keto mousse recipe.

Since this is a keto-friendly mousse recipe let’s talk about the carb content. This recipe has 4 servings, so for 1 serving, it has only 4.1 NET Carbs

Compare that to a regular serving of chocolate mousse, where it can have as many as 20-25 NET Carbs per serving.

What Types of Mousse Can I Have on a Keto Diet?

I’m always looking to make a low carb chocolate recipe. But….what if you don’t like chocolate? What other kinds of keto mousses can you eat? Here are just a few that I can think of.

  • Pumpkin Mousse 
  • Peanut Butter Mousse
  • Strawberry Mousse
  • Berry Mousse
  • Cheesecake Mousse 
  • Lemon Mousse 
  • Avocado Chocolate Mousse
  • Chocolate Peanut Butter Mousse

What Ingredients are in Keto Chocolate Mousse?

Keto Chocolate Mousse ingredients

The thing I absolutely love about our Keto chocolate mousse is that there are only 4 ingredients in the whole recipe.  That makes it super easy to make!

Heavy Cream – When eating a low-carb diet it’s best to use heavy cream because it’s lower in carbs. Plus you want to use heavy cream because it’s the best for getting the whipped texture you want. 

Unsweetened Cocoa Powder – Make sure it’s unsweetened….that’s key when using cocoa powder in keto recipes. 

Low Carb Sweetener – You definitely need to use powdered sweetener in this recipe. Powdered is going to be the best texture, you don’t want to use a granulated one because it will be too gritty. 

Vanilla – For me, vanilla is a must flavor.

Sweetener Options for Keto Mousse

What are your low carb sweetener options? In my opinion, the best sweetener for this sugar-free chocolate mousse is going to be a Powdered Sweetener. 

My go-to brand is always Swerve when using a powdered sweetener. Another brand that sells a good powdered sweetener is Lakanto

The reason for the powdered swerve is that it’s going to give you the smoothest keto chocolate mousse. It blends perfectly with the other ingredients and doesn’t leave you with a gritty texture. 

Other options for a low carb sweetener is Powdered Allulose or Liquid Stevia. Keep in mind I have not tried making our low carb chocolate mousse with these other options but if you do please let me know how it comes out in the comment section below. 

Be careful if you use stevia because it’s not a 1:1 ratio with Swerve or Monk Fruit. I don’t use it when baking, so I’m not sure of the amount you would need. 

Here is a link for a Stevia Conversion Chart that you may find helpful.

Best Chocolate to Use

To ensure a keto-friendly chocolate mousse we used unsweetened cocoa powder. It’s the easiest way to make this keto chocolate dessert. 

When buying cocoa powder just make sure that it is unsweetened, that’s the key. I used Hershey’s Cocoa 100% Natural Unsweetened Cacao

If you end up using a Dutch Processed Cocoa Powder it will be darker and richer, so keep that in mind. 

Another chocolate alternative when making easy keto mousse is you can melt some sugar-free chocolate and add that to the cream. It may give you a little bit of a different consistency.

Milk/Cream Options

When eating keto you don’t want to use regular milk because it’s too high in carbs. So we use heavy cream when making keto chocolate mousse. To be honest with you most regular mousse recipes will have heavy cream in them too because heavy cream is what whips up so well. 

If you can’t have dairy, then what I suggest using is Full-Fat Coconut Milk. It’s a great dairy-free option.

Does Mousse Have Raw Eggs?

A mousse recipe, both keto chocolate mousse and a regular mousse can contain raw eggs. However, they are only raw egg whites, NOT egg yolks. 

When using egg whites in a recipe, it doesn’t require you to cook them. Unlike egg yolks that always need to be cooked. 

We chose not to use egg whites in this recipe, as I know a lot of other keto chocolate mousse recipes don’t use them either. We chose not to because some people just don’t feel comfortable using egg whites and we wanted to make a recipe that is pleasing to everyone.

Can I Double this Recipe?

Sure thing! Doubling this perfect keto chocolate recipe is a great idea. Anytime you are having company whether large or small you should definitely make this sugar-free chocolate mousse. 

Whip up a double or even a triple batch for your guests, top it with some fresh whipped cream, chocolate shavings, and fresh berries. It will look so fancy that your guests will think that you spent hours making the perfect dessert, yet it only took you a few minutes.

Different Variations Low Carb Chocolate Mousse

Best Keto-Friendly Chocolate Mousse

How can I change up this low carb chocolate mousse? Here are a few ways to do that:

  • Different Extracts – Instead of using vanilla try Peppermint, Orange, Raspberry, Coconut, or Almond. 
  • Chocolate Coffee Mousse – Add a small scoop of Instant Espresso. 
  • Coconut – Top with some unsweetened shredded coconut. Chocolate and coconut go great together. 
  • Fresh Fruit – Adding some delicious fruit like raspberries or strawberries are the perfect addition to your low carb chocolate mousse. 
  • Add Peanut Butter – When whipping the cream and cocoa powder together add a few tablespoons of creamy peanut butter. Just be sure the peanut butter is natural and doesn’t have any added sugar.

Can You Make Keto Mousse with Cream Cheese?

Cream cheese is an ingredient that you can add to this keto chocolate mousse recipe, but it’s not necessary. In fact, if you have seen my recipe for Keto Pumpkin Mousse then you noticed that I used cream cheese in it. 

If you want to add cream cheese to this keto chocolate mousse recipe then you should add 8 oz of cold cream cheese. Keep in mind it will add some extra calories to your low carb mousse but will make it even creamier. 

Tools to Use

For this keto chocolate mousse recipe, you don’t need much to make it. 

  • Mixing Bowl 
  • Stand Mixer or Hand Mixer 
  • Measuring Cups 
  • Pastry Bag or Ziploc Bag
Keto Chocolate Mousse and piping bag

How to Make Chocolate Mousse from Scratch 

Let me walk you through how to make the easiest keto chocolate mousse recipe.

Mixing the Ingredients

Step 1: Place a large mixing bowl in the freezer for about 10-15 minutes. This helps the heavy cream to whip much faster. Do not skip this step!

icy bowl for Keto Chocolate Mousse

Step 2: Grab the bowl from the freezer, and pour in the heavy cream. Using a hand or stand mixer start whipping the cream. It should only take a minute or two to become creamy.

Step 3: Now add the cocoa powder, powdered swerve, and vanilla. Whip all the ingredients together until desired consistency. I like my mousse to be a bit on the thicker side.

Chilling It

Step 4: I recommend chilling your keto chocolate mousse for about 30 minutes or so. It helps the texture to stay firmer. 

If you are in a hurry and don’t mind it not being super cold then go ahead and serve it right away. Otherwise, place it in the fridge for 30 minutes then serve.

Step 5: Scoop the mousse into a small bowl or cups. If you want to get a bit fancier then put the keto mousse into a piping bag then into your cup of choice.

Best Tips for Creamy Keto Chocolate Mousse

  • Chill the mixing bowl for 15-20 minutes before whipping the cream. It will help to whip the cream much faster. 
  • Don’t over-whip the cream before you add in the rest of the ingredients. 
  • Be sure to use a powdered low carb sweetener, don’t use granulated. 
  • Unsweetened cocoa powder – I used Hershey’s Unsweetened Cocoa, but use whatever brand you prefer. Just make sure it’s unsweetened, that’s key. 
  • Mix until stiff peaks are formed. After cocoa powder, sweetener, and vanilla have been added, mix until you have reached the desired consistency.  
  • Adjust to taste – taste the keto chocolate mousse before serving to make sure it’s to your liking. Add more sweetener if needed. 
  • For a fancier look, use a piping/pastry bag. 
  • For a Dairy-Free Keto Chocolate Dessert replace the heavy cream with full-fat coconut milk.

Why is My Chocolate Mousse Runny?

Ok so if you ended up with a runny keto chocolate mousse….that’s not good. But have no fear you can fix it. 

Having a runny sugar-free chocolate mousse probably just means that you didn’t whip it enough. Using your hand mixer or stand mixer start whipping the mousse again. 

You can tell it’s done when you start getting stiff peaks in the bowl. Then pop it in the fridge until you are ready to serve it.

Why Is My Low Carb Chocolate Mousse Grainy?

If you ended up with a low carb chocolate mousse that tastes grainy then it’s because you didn’t use Powdered Sweetener. It really is key in this recipe. 

You don’t want to use a granulated sweetener, but if that is all you have then put it into a food processor and grind it until it becomes a powder.

Making Keto Mousse Sweeter

Best Keto Chocolate Mousse Recipe

I found that once you stop eating sugar your tastebuds change and most likely you will find desserts being too sweet. If that hasn’t happened to you yet, and you find this keto mousse recipe not sweet enough, it’s ok we can fix that. 

Start by adding 1 tbsp powdered swerve at a time and taste test it until you reach your desired sweetness.

Other Diets This Recipe is Good For

Gluten-Free: This recipe is 100% gluten-free! 

Egg-Free: If you have an egg allergy then go ahead and enjoy this keto chocolate mousse. Other chocolate mousse recipes contain egg whites, but this one is completely egg-free. 

Nut-Free: Finding nut-free recipes on keto can be hard at times due to the fact that almond flour is such a common ingredient. But in this keto chocolate mousse recipe, there are absolutely no nuts. 

Dairy-Free: There is heavy cream in this recipe so it’s not dairy-free. But you can replace the heavy cream with coconut milk instead, now you have a great dairy-free low carb chocolate mousse.

Can I Make Keto Mousse Dairy-Free?

Yes, you can make this keto chocolate mousse dairy-free if you need to. Instead of using heavy cream, replace it with coconut milk instead. 

Be sure to use full-fat coconut milk and not reduced-fat coconut milk. The full-fat coconut milk will give you a better-whipped consistency.

How to Serve Low Carb Chocolate Mousse?

Leftover mousse can be stored in an airtight container in the fridge for 3-5 days.

Can You Freeze Chocolate Mousse?

Yes, you can freeze your leftover keto chocolate mousse. All you need to do is place it in an airtight container and place it in the freezer for up to 2 months

When you are ready to serve it, take it out of the freezer and let it thaw on the counter.
