Ingredients For Easy Keto Mousse
- Heavy whipping cream – Gives mousse its creamy and rich texture.
- Sugar free powdered sweetener – Makes it sweet without sugar. I usually use a brand like Swerve, but any powdered sweetener works.
- Unsweetened cocoa powder – The main chocolate flavor comes from this. Make sure to use unsweetened to keep carbs low.

Kitchen Tools For Keto Mousse
To make this yummy mousse, you'll need a large mixing bowl and an electric hand mixer. If you don’t have a hand mixer, you can use a stand mixer, but I think the hand mixer is easier to clean up.

How To Make Keto Chocolate Mousse With Three Ingredients
- Whip the cream and sweetener: Grab your mixing bowl and mix the heavy cream with the sweetener. I use medium speed for about a minute to get it nice and blended.


- Add cocoa powder and keep mixing: Dump in the cocoa powder and whip it on high until you see stiff peaks. It usually only takes another minute or two.


- Chill and serve: Pop it in the fridge for an hour so it gets that yummy mousse texture. When you’re ready, scoop the chocolate mixture into cups or bowls. You can eat it sooner if you’re in a hurry, but it gets thicker as it chills.

Tips For 3-Ingredient Keto Chocolate Mousse
Tip 1: For the best texture, be sure not to overmix once the mousse thickens.
Tip 2: Use really cold, heavy cream. It whips faster and holds the peaks better.
Tip 3: Powdered sweeteners work way better than granulated. If you only have granulated sugar, use a blender to break it up.
Tip 4: Don’t skip chilling if you want it extra creamy and thick.
FAQs For Easy Low Carb Chocolate Mousse
Yes, you can whip it by hand with a whisk, but it takes a lot longer, and you’ll need some elbow grease!
You want a powdered, sugar-free sweetener to keep it keto and smooth. Monk fruit, allulose, or erythritol-based blends work.
Keep any leftovers in a covered container in the fridge. The mousse stays good for up to 3 days, though it’s always gone in my house way before then.
