This chilled dessert consists of heavy cream beaten with unsweetened cocoa powder and a powdered sugar-free sweetener. The ingredients are whisked together until light and fluffy, creating a silky and airy consistency. This recipe uses simple pantry staples to create a layered chocolate flavor in a sugar-free dessert.
About This Recipe
To prepare the mousse, the cocoa powder and sweetener are sifted together before being combined with chilled heavy cream and vanilla extract. The mixture is beaten with an electric mixer to incorporate air, which gives the light, airy texture without the need for eggs. It is important to chill the finished mousse for at least thirty minutes to allow the structure to firm up before serving.
The flavor relies on the intensity of the unsweetened cocoa powder balanced by the richness of the heavy cream. Using a powdered sweetener ensures a smooth consistency that blends easily into the cream without leaving a grainy mouthfeel. Since the recipe includes a pinch of sea salt, the depth of the chocolate is enhanced, providing a more complex taste.
The mousse works well as a dessert and can be prepared ahead of time. It’s easy to customize the servings by adding sugar-free whipped cream or topping the mousse with dark chocolate shavings for extra texture. This mousse is best served chilled in individual glasses, offering a structured and indulgent finish to a meal.
