This 5-Ingredient Super-Decadent Blender Keto Chocolate Mousse lives up to its name. Rich, silky, and surprisingly simple, it’s a keto-friendly dessert you’ll want to make again and again.
How to make this 5-Ingredient Super-Decadent Blender Keto Chocolate Mousse
You only need five ingredients: very dark chocolate (minimum 85% cocoa), heavy cream, a powdered sweetener such as erythritol, one egg, and a pinch of unrefined sea salt. A little sea salt brings out the deep chocolate flavor and balances the sweetness.
Equipment is minimal: a blender and a small saucepan to heat half of the cream.
The process is straightforward. Start by adding the egg, chopped chocolate, and powdered sweetener to the blender. Heat half of the cream with the salt until it’s piping hot (not boiling). With the blender running at low speed, slowly pour the hot cream into the blender so it melts the chocolate and warms the egg. Blend until smooth and glossy. Whip the remaining cream to soft peaks, then fold it into the chocolate mixture to lighten the mousse. Chill for at least an hour to set.
Note: this recipe uses an egg that will be exposed to the hot cream, which effectively pasteurizes it. If you prefer, use a pasteurized egg for extra caution.
Below are the step-by-step photos and directions to guide you through the process.
Take 4 oz (115 g) of very dark chocolate—Lindt 85% is a great choice. Chop it into smaller pieces and set aside.
Add one egg to the blender jar, then add the chopped chocolate and your sweetener of choice. I use about 2 tablespoons of powdered erythritol to keep the mousse pleasantly restrained in sweetness.
Pour 1/2 cup (120 ml) heavy cream into a small saucepan, add a pinch of sea salt, and heat until piping hot but not boiling.
With the blender running on low speed, slowly pour the hot cream into the blender so it melts the chocolate and warms the egg. Continue blending about 1 minute, until the mixture is completely smooth and glossy. Avoid high speed to keep the mousse light rather than dense.
Set the melted chocolate mixture aside briefly. Whip the remaining 1/2 cup (120 ml) heavy cream until soft peaks form.
Gently fold the whipped cream into the chocolate base until fully combined and airy.
Transfer the mousse into 4–6 serving bowls, cover, and chill in the refrigerator for at least one hour or until set. Decorate just before serving—fresh tart berries and a dollop of whipped cream are lovely accompaniments. Lingonberries or raspberries add a bright contrast to the rich chocolate.
Background: how this recipe came to be
I wanted a very simple, blender-based chocolate mousse adapted for keto. Traditional recipes often call for bittersweet chocolate and sugar, and sometimes even water, which felt wrong to me for something meant to be rich and creamy. My first trial used water and produced a watery, thin result. Replacing the water with heavy cream made the mousse rich but too stiff. Adjusting the amount of whipped cream (whipping only to soft peaks) and blending on low speed when adding hot cream fixed the texture. The final version is thick yet airy and intensely chocolatey—exactly what I wanted.

Tips and variations
This mousse is excellent as written, but you can customize it easily:
- Mint: add 1–2 drops of pure peppermint oil or 1/4 cup chopped fresh mint.
- Orange: stir in 1 tablespoon fresh grated orange zest (only the orange part).
- Flavored extracts: try natural hazelnut, cherry, almond, or raspberry flavoring for different profiles.
- Try alternative sweeteners like monk fruit or flavored stevia—adjust to taste, especially with very dark chocolate.
- Mexican-style: add 1–2 teaspoons Ceylon cinnamon and a pinch of cayenne for warmth and spice.
- Texture: fold in crushed roasted hazelnuts, freeze-dried raspberries, or finely grated dark chocolate for a little crunch.
- Lower carbs: use darker chocolate—100% cocoa has the fewest carbs but is very intense; increase sweetener if needed.
- Dairy-free: use thick, whippable coconut cream without additives.
Notes from the author
I developed this recipe while simplifying a classic blender mousse to fit a clean keto approach. Replacing water with heated cream and whipping the remaining cream to soft peaks created a mousse that is rich, airy, and perfectly balanced. It’s become a favorite for its ease and decadent taste.
