Step‑by‑Step Instructions for Tuxedo Cake – Triple Chocolate Mousse Cake
Step 1: Prepare the Cake Batter
Preheat your oven to 350°F (175°C). In a large mixing bowl, whisk together the dry ingredients: all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. In a separate bowl, combine wet ingredients: whole milk, eggs, sour cream, vegetable oil, espresso powder, and vanilla extract. Mix the wet and dry ingredients until just combined, then gradually stir in hot water to create a thin, smooth batter.
Step 2: Bake the Cake Layers
Divide the cake batter evenly between two greased 9-inch round cake pans. Place them in the preheated oven and bake for 30-35 minutes, checking for doneness with a toothpick inserted into the center; it should come out clean. Once done, remove them from the oven and allow the cakes to cool in the pans for 10 minutes before transferring them onto wire racks to cool completely.
Step 3: Make the Chocolate Mousses
In a saucepan, heat one cup of heavy cream until steaming, but not boiling. Meanwhile, whisk together the egg yolks, granulated sugar, and cornstarch in a separate bowl. Gradually add the hot cream to the yolk mixture while whisking continuously, then return the mixture to the saucepan and cook over medium heat until it thickens. Split the custard between two bowls, adding melted dark chocolate to one and melted white chocolate to the other. Fold in whipped cream to each for light, airy mousses.
Step 4: Assemble the Cake
Once the cake layers have completely cooled, place one layer on a serving plate. Spread the dark chocolate mousse evenly on top, ensuring a nice even layer. Gently place the second cake layer on top, followed by the white chocolate mousse. Smooth the top layer with a spatula for an elegant finish, then cover the cake and refrigerate for at least 2 hours to let the mousses set.
Step 5: Create the Ganache
To prepare the ganache, heat the remaining cup of heavy cream in a small saucepan until just simmering. Pour the hot cream over the chopped milk chocolate in a bowl and let it sit for a few minutes. Whisk until smooth and glossy. Once the ganache is ready, carefully pour it over the chilled cake, allowing it to drip down the sides for a beautiful finish.
Step 6: Final Chill and Serve
Refrigerate the decorated cake for at least 30 minutes to allow the ganache to set properly. For the best flavor and texture, it’s recommended to chill the cake overnight before serving. When ready to serve, slice with a warm knife for clean cuts, and enjoy every layer of this incredible Tuxedo Cake – Triple Chocolate Mousse Cake!

Make Ahead Options
These Tuxedo Cake – Triple Chocolate Mousse Cake layers are perfect for busy home cooks looking to save time! You can bake the cake layers up to 24 hours in advance; simply wrap them in plastic wrap after they are completely cooled to maintain moisture. The chocolate mousses can be made up to 3 days ahead as well—just refrigerate them in airtight containers to keep them fresh. When you’re ready to assemble the cake, layer the cooled cake with the prepared mousses, and refrigerate for at least 2 hours or overnight for the best flavor. Finish by adding the ganache and chilling for 30 minutes before serving, ensuring your cake stays just as indulgent and delightful!

Chill the Layers: Refrigerate each mousse layer for at least 2 hours before assembling; this helps them set properly and maintain structure.
-
Use Quality Chocolate: Always opt for high-quality chocolate bars for both the mousses and ganache; this ensures a rich, authentic chocolate flavor.
-

Knife Technique: Dip a sharp knife in warm water before slicing the cake; this allows for cleaner cuts and preserves the beautiful layers inside.
How to Store and Freeze Triple Chocolate Mousse Cake
Fridge: Store the assembled cake in the refrigerator, tightly wrapped in plastic wrap, for up to 3 days. This keeps the mousse layers fresh and preserves their flavors.
Freezer: For longer storage, freeze the cake for up to 3 months by wrapping it tightly in plastic wrap and then aluminum foil to prevent freezer burn.
Thawing: To enjoy later, transfer the frozen cake to the fridge for 6-8 hours or overnight to thaw gently before serving.
Reheating: If desired, slices can be gently warmed in the microwave for 10-15 seconds, just enough to take the chill off without melting the mousse layers.

Tuxedo Cake – Triple Chocolate Mousse Cake Recipe FAQs
What type of chocolate should I use for the mousse?
Absolutely! I recommend using high-quality chocolate bars, as they melt beautifully and enhance the overall flavor of your Triple Chocolate Mousse Cake. Look for brands like Ghirardelli or Callebaut, which offer a rich chocolate experience. Avoid using chocolate chips, as they don’t melt as smoothly.
How do I ensure my eggs reach the correct temperature for the mousse without scrambling?
Very well! To prevent scrambling when making the custard for your mousse, whisk the egg yolks, sugar, and cornstarch in a bowl. Gradually add the hot cream into this mixture while whisking continuously. Then, return it to the saucepan and cook over medium heat, stirring gently until it reaches 160°F. A candy thermometer is a great tool to ensure this perfect temperature.
How can I keep the mousse layers from sinking into the cake?
A little trick here! Refrigerate each mousse layer for at least 2 hours before assembling your cake. This helps the mousse set and maintain its structure, preventing any sinking when you layer the cake. Plus, chilling increases the intensity of those chocolate flavors!
What is the best way to store leftover Tuxedo Cake?
For sure! Store the assembled cake in the refrigerator, tightly wrapped in plastic wrap, for up to 3 days. This keeps the mousse fresh while preventing it from absorbing any fridge odors. If you want to keep it longer, wrap it tightly in plastic wrap and aluminum foil and freeze it for up to 3 months. Just remember to thaw it in the fridge overnight before serving.
Can I make substitutions to suit dietary restrictions?
Absolutely! For a gluten-free option, substitute the all-purpose flour with a gluten-free almond flour blend. For dairy-free, replace heavy cream with coconut cream and use dairy-free chocolate. If you’re looking for a lighter version, swap sour cream for Greek yogurt and reduce the sugar. This way, everyone can enjoy a slice of your decadent chocolate delight!
How do I achieve clean cuts when serving the cake?
Very nice question! To achieve beautifully clean slices of your Triple Chocolate Mousse Cake, dip a sharp knife in warm water before each cut. Wipe it off after each slice to maintain that stunning layered look. This little tip keeps the mousse intact and looking fabulous for your guests!
