If you love chocolate like I do, you need this wonderful homemade Keto Chocolate Mousse recipe.
Ingredients
- Chocolate Chips - My go-to brand is Lily's, which is sweetened with Stevia.
- Egg Whites - These will give the mousse its light and airy texture.
- Heavy Cream - If you eat low carb rather than strict keto, you could use half and half instead.
- Swerve Confectioners - You want a powdered low-carb sweetener to blend easily into the mousse.
- Vanilla Extract - This makes a big difference in flavor. I recommend the highest quality you can find!
- Salt - It really enhances the chocolate flavor. I use finely ground sea salt.
Tips & Tricks
- Don't let water touch the chocolate while you are melting in a double boiler or in the microwave. Any liquid can cause the chocolate to seize up.
- When choosing your chocolate, you can use milk, semi-sweet, or dark Lily's chocolate. (Or your prefered brand of keto chocolate.) It all depends on your personal preference.
- If you use another sweetener instead of Swerve Confectioners, make sure it is powdered. If you have granulated sweetener, you can throw it in your blender to powder it.
Frequently Asked Questions
There are 3.6 net carbs per serving of this Keto Chocolate Mousse. Please keep in mind that this is just for the mousse and doesn't include any toppings you may add.
Yes! Just make sure you are choosing a sugar-free version without any added fillers.
The easiest thing to do is to whip up your own whipped cream right at home. All you need is heavy whipping cream and your favorite low-carb sweetener to taste. Mix with hand beaters or an immersion blender, and you'll have whipped cream in less than a minute!
If you are low carb and not strict keto, you can use store-bought whipped cream as well. Most have less than 1 gram of sugar per serving, so they are fine in moderation.
If you have any extra of this recipe, it will stay fresh for up to 5 days in the fridge.
In terms of how long it will last… if your family is anything like mine, you may need to make a double batch, otherwise, it could be gone in less than a day! (Because...teen boys.)
There are two main reasons your mousse could separate. The first has to do with the chocolate, and the second has to do with the egg whites.
If the chocolate seizes while melting, it will be tough to whip with the rest of the mousse. That's why you want to avoid letting any water touch the chocolate as it's melting.
Second, you want to make sure you don't overbeat the eggs. Otherwise, they could become grainy. I recommend beating the eggs until they form soft peaks, but you don't want them to become stiff peaks.

How To Make Keto Chocolate Mousse
Start by placing the chocolate in the top of a double boiler filled with simmering water. Let the chocolate melt, stirring occasionally.
Alternatively, you can melt the chocolate in a glass bowl in the microwave. Heat in 30-second increments, stirring in between each one, until the chocolate is fully melted.
Allow the chocolate to cool slightly.
In the bowl of a stand mixer, beat the egg whites to soft peaks. You want to avoid overbeating.
In a medium bowl, whip the heavy cream with the Swerve and vanilla until it is well combined.
Next, add the cream mixture to the chocolate. Stir until the mixture is thoroughly combined.
Then, add the egg whites, stirring gently to avoid deflating.
Finally, divide the mousse between serving dishes and refrigerate for at least 1 hour.
