How To Make

  1. Beat heavy cream and sugar free powdered sweetener in a medium bowl until well mixed.

  3. Refrigerate for 1 hour (if you can't wait, it's okay to eat right away). Enjoy!

Olivia's Top Tips

  • Use cold heavy cream - Starting with cold cream helps it whip up faster and hold its shape better, giving you that light, airy texture.
  • Sift the cocoa powder - Cocoa powder loves to clump, so give it a quick sift before adding it in. It makes the mixing smoother and the mousse fluffier. That is an extra step so feel free to skip.
  • Don't overwhip - Stop once you hit stiff peaks. If you go too far, the mousse can turn grainy or start to separate, and no one wants chocolate butter (or maybe they do, ha!)

And that's it! I hope this becomes one of those staple dessert recipes for you. It's simple, satisfying, and just the right amount of sweet. Let me know if you make it, I'd love to hear what you think! xoxo Olivia

This 3-ingredient keto chocolate mousse is rich, fluffy, and easy to make. Just whip it up in one bowl, let it chill, and you've got a silky, chocolatey dessert for after dinner. Perfect for late-night cravings or make-ahead treats during the week.

Ingredients

  • 1 cup heavy whipping cream
  • ¼ cup sugar-free powdered sweetener (I used allulose)
  • ¼ cup unsweetened cocoa powder

Instructions

  • Beat heavy cream and sugar free powdered sweetener in a medium bowl until well mixed.
  • Add the cocoa powder and mix on high until stiff peaks form.
  • Refrigerate for 1 hour, then enjoy!

Notes

1. Sweeteners - Use what works best for your lifestyle. I typically use Monk fruit and allulose in all my recipes. They are natural sweeteners that won't spike blood sugar. For this recipe, I used an allulose-based powdered sugar substitute because it behaves almost exactly like sugar in this recipe.
2. Nutrition and carbs – Be aware that some recipe blogs omit sugar alcohols and allulose from the nutrition calculation. For transparency, I have included it and calculated the net carbs below. Always use a carb counter app like Cronometer according to the brands you use in order to get accurate nutrition information.
13.74 Total Carbs – 1.99 Fiber –  9.00 Allulose = 2.75 Net Carbs per serving
