How to Make Tuxedo Cake – Triple Chocolate Mousse Cake
Step 1: Make the Chocolate Cake
Preheat your oven to 350°F (180°C). Grease and line two 8-inch round cake pans. This ensures that your cakes come out perfectly without sticking! In a large mixing bowl, sift together flour, sugar, cocoa powder, baking powder, baking soda, and salt. Whisking these dry ingredients well helps to evenly distribute everything before adding wet ingredients.
In another bowl, whisk together eggs, milk, sour cream, oil, and vanilla until smooth. Adding room temperature ingredients promotes better mixing and results in a fluffier cake! Combine these wet ingredients with the dry ones until fully mixed.
Now comes the secret weapon: dissolve espresso powder in hot water and pour it into the batter. This step enhances the richness of your chocolate flavor. Divide the batter evenly between prepared pans and bake for about 35 minutes. When a toothpick comes out clean from the center—your cakes are done! Let them cool completely before removing them from their pans.
Step 2: Make the Chocolate Mousses
Place your chopped dark and white chocolate in separate bowls. In another bowl, whisk egg yolks with sugar and cornstarch until pale; this is crucial as it will give body to your mousse! Heat one cup of cream with vanilla over medium-low heat until steaming but not boiling.
Slowly drizzle this hot cream into your egg yolk mixture while whisking constantly—it’s important to temper those yolks so they don’t scramble! Pour everything back into the saucepan and cook over medium heat while whisking until thickened.
Now divide this custard between both bowls of chocolate. Stir until melted—how heavenly does that smell? Whip up another cup of cream to stiff peaks then fold half into each bowl of mousse gently so you keep all that airiness intact!
Step 3: Assemble the Cake
Begin by placing one layer of cake at the bottom of a cake ring on your serving plate. Spread dark chocolate mousse over this layer evenly—this is where we start building those decadent levels of flavor! Carefully add white chocolate mousse on top before chilling in the fridge for about 30 minutes to set.
Once set, add your second layer of cake on top and chill again for at least four hours—or overnight if you can resist! This waiting time allows all those flavors to meld beautifully together.
Step 4: Make the Chocolate Ganache
Heat another round of cream in a saucepan until steaming—again avoiding boiling! Pour this hot cream over chopped milk chocolate allowing it to sit for one minute before stirring until smooth. Letting ganache cool slightly thickens it up making spreading easier.
Spread ganache generously over chilled cake letting it drip joyfully down the sides. It’s like giving your cake an elegant tuxedo!
Step 5: Decorate
Garnish with fun toppings like chocolate shavings or colorful sprinkles if you’re feeling festive! Once decorated nicely—refrigerate until ready to serve.
And there you have it—a stunning Tuxedo Cake – Triple Chocolate Mousse Cake that will wow everyone around you! Enjoy every rich bite—it’s pure bliss on a plate.
Pro Tips for Making Tuxedo Cake – Triple Chocolate Mousse Cake
Creating the perfect Tuxedo Cake is all about attention to detail and a little love in every step. Here are some pro tips to ensure your cake turns out just as delicious as you envision!
-
Use Room Temperature Ingredients: Let your eggs, sour cream, and milk sit out before baking. Room temperature ingredients mix together more easily, resulting in a smoother batter and a fluffier cake.
-
Measure Accurately: Baking is a science, so precise measurements are crucial. Use a kitchen scale for the best results, especially with dry ingredients like flour and sugar.
-
Don’t Overmix the Batter: Once you combine wet and dry ingredients, mix until just combined. Overmixing can lead to a dense cake instead of the light texture you want.
-
Chill Between Layers: After adding each mousse layer, chilling the cake helps it to set up nicely. This step ensures that your layers maintain their shape when serving.
-
Experiment with Garnishes: Feel free to get creative with toppings! Chocolate shavings or fresh berries not only enhance the visual appeal but also add delightful textures and flavors.

Side Dishes

- Fresh Fruit Salad: A refreshing fruit salad balances out the richness of the cake. Choose seasonal fruits for an extra burst of flavor.
- Coffee or Espresso: Serving coffee or espresso alongside enhances the chocolate experience while providing a warm beverage option for your guests.
