How to Make It (Step-by-Step Method)
Begin by preparing the chocolate cake. Preheat your oven to 350°F (175°C) and grease a springform pan, lining the bottom with parchment paper. In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, salt, and sugar. In a separate bowl, mix eggs, oil, buttermilk, melted butter, and vanilla until smooth. Gradually combine wet and dry ingredients, then stir in hot coffee or water. The batter will be thin—this ensures a moist cake.
Pour the batter into the prepared pan and bake for 30–35 minutes, until a toothpick inserted in the center comes out clean. Let the cake cool completely in the pan, then level the top if needed. Leave the cake in the springform pan, as it will serve as the base for the mousse layers.
For the dark chocolate mousse, bloom gelatin in cold water. Melt dark chocolate gently over a double boiler or in short microwave bursts. Warm a small portion of cream and dissolve the gelatin into it, then stir into the melted chocolate. Let cool slightly. Whip remaining cream to soft peaks and gently fold into the chocolate mixture. Spread evenly over the cooled cake and refrigerate for 20–30 minutes until set.
Repeat the process for the milk chocolate mousse, carefully layering it over the dark chocolate layer once firm. Chill again until lightly set. Finish with the white chocolate mousse, smoothing the top with an offset spatula for a clean, elegant finish. Refrigerate the cake for at least 4 hours, or overnight, to fully set.
Before serving, release the springform pan gently. For ultra-clean slices, dip a sharp knife in hot water and wipe between cuts.

Serving Suggestions
This Triple Chocolate Mousse Tuxedo Cake deserves a presentation that matches its elegance. Serve it on a simple cake stand or white platter to highlight the dramatic layers. A light dusting of cocoa powder or chocolate shavings on top adds a refined finishing touch without overpowering the cake’s sleek appearance. For added contrast, a few fresh raspberries or strawberries placed around the base provide a pop of color and a hint of acidity to balance the richness.
When serving guests, slice thin wedges—this cake is rich, and smaller portions allow everyone to savor it without feeling overwhelmed. For dinner parties, pair each slice with a dollop of lightly sweetened whipped cream or a drizzle of raspberry coulis. Coffee lovers will appreciate serving it alongside espresso or strong brewed coffee, while a glass of cold milk keeps things classic. No matter how it’s plated, this cake instantly elevates the table and signals that something special is being served.
Storage + Meal Prep
This cake stores beautifully, making it ideal for advance preparation. Once fully set, cover the cake loosely with plastic wrap or store it in an airtight cake container. Kept refrigerated, it will stay fresh for up to four days without losing its texture or flavor. In fact, the mousse layers often become even silkier after a full day of chilling.
For longer storage, the cake can be frozen. Freeze uncovered until firm, then wrap tightly in plastic wrap followed by foil. It can be frozen for up to one month. To serve, thaw overnight in the refrigerator—never at room temperature, as the mousse layers are delicate. Avoid freezing garnishes; add fresh toppings just before serving. If the surface appears slightly dull after thawing, a light dusting of cocoa powder or chocolate curls instantly refreshes its appearance.
Conclusion
The Triple Chocolate Mousse Tuxedo Cake is more than a dessert—it’s an experience crafted for true chocolate lovers. With its moist cake base and three distinct mousse layers, it delivers depth, balance, and undeniable elegance in every bite. It’s the kind of recipe that turns celebrations into memories and ordinary moments into something extraordinary.
