This rich and creamy keto chocolate mousse is whipped from cold heavy whipping cream, unsweetened cocoa powder, powdered erythritol, and a hint of vanilla for a deeply chocolatey dessert without the sugar crash. Each chilled serving is silky, airy, and satisfying, with an intense chocolate flavor that is sweet but not overpowering, keeping carbs low and fat high for perfect keto macros.

Ingredients

For the keto chocolate mousse

1 cup cold heavy whipping cream
1/4 cup powdered erythritol or erythritol-based sweetener
3 tablespoons unsweetened cocoa powder Dutch-processed if possible for smoother flavor
1 teaspoon pure vanilla extract
1/8 teaspoon fine sea salt enhances chocolate flavor

Optional toppings

1/4 cup keto whipped cream lightly sweetened with erythritol, for garnish
2 tablespoons fresh raspberries or strawberries use a few berries per serving, optional
1 tablespoon shaved sugar-free dark chocolate 85% cacao or higher, optional

Instructions

Place a medium mixing bowl and the beaters of a hand mixer in the refrigerator for at least 10 minutes so they are well chilled.
Add the cold heavy whipping cream to the chilled bowl and beat on medium speed until it becomes slightly thick and soft peaks just begin to form.
In a small bowl whisk together the powdered erythritol, unsweetened cocoa powder, and fine sea salt to break up any lumps.
With the mixer running on low speed, gradually sprinkle the cocoa and sweetener mixture into the cream, then add the vanilla extract.
Increase the mixer speed to medium high and whip until the mousse is thick, smooth, and forms medium to stiff peaks, stopping to scrape down the sides of the bowl as needed and taking care not to overwhip into butter.
Taste the mousse and adjust sweetness by gently folding in a little more powdered erythritol if desired.
Spoon the mousse evenly into four small ramekins or dessert glasses and smooth the tops with a spatula.
Cover and refrigerate the mousse for at least 1 hour to fully chill and set, or up to 3 days for make-ahead desserts.
Before serving, garnish the mousse with keto whipped cream, a light dusting of cocoa powder, a few fresh berries, or shaved sugar-free dark chocolate if using.

Notes

For the best texture, keep the heavy cream very cold and avoid overwhipping once it thickens, as the mousse can turn grainy. Powdered erythritol dissolves more smoothly than granulated, so pulse granulated sweetener in a blender if needed before using. A tiny pinch of salt deepens the chocolate flavor without making the mousse taste salty. Store the mousse tightly covered in the refrigerator for 3 to 4 days, or freeze for up to 1 month and thaw overnight in the refrigerator before serving. If the texture looks slightly separated after chilling or freezing, whisk gently by hand until creamy again.
