This elegant, no-bake dessert features an airy, whipped mousse infused with deep cocoa and a smooth hazelnut aroma. Made with sugar-free dark chocolate and stabilized with heavy cream, the cups offer a silky, melt-in-the-mouth texture that mimics traditional gourmet chocolate spreads. Finished with a topping of toasted hazelnuts for added crunch, it provides a sophisticated and portion-controlled low-carb treat that is both rich and refreshing.

About This Recipe

The preparation begins by folding melted sugar-free chocolate into a base of heavy cream whipped with cocoa powder and powdered sweetener. This process creates a light yet stable emulsion that achieves a dense, luxurious body after a short period of chilling. The addition of hazelnut and vanilla extracts provides a continuous aromatic warmth, while a pinch of salt sharpens the intensity of the dark cocoa without increasing the carbohydrate count.

The flavor is defined by the balance between the slightly bitter notes of the dark chocolate and the nutty, toasted profile of the hazelnuts. High-fat dairy provides the necessary richness to carry these bold flavors, resulting in a smooth consistency that holds its shape when piped or spooned into serving cups. Because the recipe avoids liquid syrups or starches, the mousse remains airy and mousse-like rather than becoming heavy or fudge-like.

Typically served chilled in individual jars or glasses, these mousse cups are a functional and visually appealing choice for dinner parties or holiday dessert spreads. They are easily garnished with extra whipped cream or shaved chocolate to enhance their professional, bakery-style appearance. The combination of its quick, no-heat assembly and its classic, indulgent flavor profile makes it a reliable and refined option for those seeking a high-fat, low-carb dessert with minimal effort.
