Step‑by‑Step Instructions for Tuxedo Cake – Triple Chocolate Mousse Cake
Step 1: Preheat and Prepare Pans
Preheat your oven to 350°F (175°C) while you grease and line two 9-inch round cake pans with parchment paper. This will ensure your Tuxedo Cake layers release easily after baking. Once prepared, set the pans aside and have your mixing bowls and whisk ready to combine your ingredients.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. Make sure to blend them well until there are no lumps, creating a smooth, even mixture. This dry blend is crucial for an even rise in your Tuxedo Cake, setting the foundation for its delicious flavor.
Step 3: Combine Wet Ingredients
In a separate bowl, combine the wet ingredients: whole milk, large eggs, sour cream, and vegetable oil. Whisk until smooth and homogenous, then mix in the vanilla extract and espresso powder if using. It’s important to ensure your wet ingredients are well-mixed, as they will transform your dry ingredients into a luscious batter.
Step 4: Create the Cake Batter
Slowly add the wet mixture into the dry ingredients, stirring gently with a spatula until just combined. To make the batter thin and easy to pour, gradually add hot water while mixing until you achieve a smooth consistency. This step is key to a tender cake, so take care not to overmix here!
Step 5: Bake the Cake
Pour the batter evenly into the prepared cake pans, and place them in your preheated oven. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. That’s how you know your Tuxedo Cake layers are perfectly baked! Allow them to cool in the pans for 10 minutes before turning them onto wire racks.
Step 6: Prepare the Dark Chocolate Mousse
In a small saucepan, heat half the heavy cream over medium heat until it simmers, then set aside. In a bowl, whisk egg yolks, sugar, and cornstarch until smooth. Gradually add the hot cream to the egg mixture, whisking constantly, then return it to the stove until thickened. Stir in the dark chocolate until melted and smooth.
Step 7: Prepare the White Chocolate Mousse
Repeat the same process used for the dark chocolate mousse, using the remaining heavy cream and focusing on the white chocolate this time. After the mixture thickens and you’ve stirred in the melted white chocolate, fold whipped cream into both mousse mixtures gently. This ensures they remain airy and light.
Step 8: Assemble the Cake
On a serving plate, place one layer of the cooled Tuxedo Cake and spread the dark chocolate mousse evenly on top. Carefully place the second cake layer on top of the mousse, followed by the white chocolate mousse spread evenly on the surface. Refrigerate the assembled cake for at least 2 hours to set the mousses.
Step 9: Prepare the Ganache
To make the ganache, heat the remaining heavy cream until it simmers and pour it over the milk chocolate in a bowl. Let it sit for a few minutes, then stir until the mixture is smooth and glossy. This rich ganache will provide a luxurious finish to your Tuxedo Cake.
Step 10: Apply the Ganache
Carefully pour the ganache over the chilled assembled cake, allowing it to drizzle down the sides for an elegant effect. Use a spatula to smooth it out if desired. This final touch transforms your Tuxedo Cake into a stunning centerpiece. Return the cake to the refrigerator for 30 minutes before serving.

How to Store and Freeze Tuxedo Cake
Room Temperature: Leave the cake at room temperature for up to 1 day if covered, to preserve its flavors and textures.
Fridge: Store the Tuxedo Cake in an airtight container in the refrigerator for 3-4 days. This will keep the mousse layers fresh and prevent drying out.
Freezer: For longer storage, wrap slices individually in plastic wrap and freeze for up to three months. Thaw in the fridge before serving to maintain texture.
Reheating: If you prefer a slightly warm cake, gently warm individual slices in the microwave for 10-15 seconds, but be cautious not to overheat!
Make Ahead Options
These Tuxedo Cake – Triple Chocolate Mousse Cake preparations are perfect for busy home cooks aiming to save time during special occasions! You can bake the cake layers up to 24 hours in advance. Just cool them completely, wrap them tightly in plastic wrap, and store them in the refrigerator to retain moisture. The chocolate mousses can also be made ahead and stored in the fridge for up to 3 days; simply cover them with parchment paper to prevent skin formation. When you’re ready to serve, assemble the cake and pour the ganache over it before refrigerating for 30 minutes. This way, your show-stopping dessert will be just as delicious and elegant!

Expert Tips for Tuxedo Cake
Use Quality Chocolates: Choose high-quality dark, milk, and white chocolate for the best flavor. Lower-quality chocolates can alter the rich, decadent taste you’re aiming for in your Tuxedo Cake.
Cool Layers Properly: Ensure the cake layers cool completely before adding mousse to prevent melting. If the cake is too warm, the mousses may lose their structure.
Gentle Folding: When incorporating whipped cream into the mousses, fold gently to maintain airiness. Overmixing can lead to heavy mousses that lack the delightful, airy texture.
Refrigerate for Best Results: Let the assembled Tuxedo Cake chill for at least 2 hours. This setting time allows the flavors to meld beautifully and improves the overall texture.
Slice with Care: Use a warm knife to cut through the ganache and mousse smoothly. A warm knife glides through the cake, preventing messy, uneven slices.

Tuxedo Cake – Triple Chocolate Mousse Cake Recipe FAQs
How do I select the best chocolate for the Tuxedo Cake?
Absolutely! For the best flavor, choose high-quality dark, milk, and white chocolates. Look for brands with a high cocoa content; this will enhance the rich and complex flavors of your Tuxedo Cake. Quality chocolate makes a significant difference, so it’s worth the investment!
How should I store leftover Tuxedo Cake?
Very simple! For short-term storage, keep the Tuxedo Cake in an airtight container in the refrigerator for up to 3-4 days. Make sure it’s properly sealed to retain moisture. If you’d like to store it longer, wrap individual slices tightly in plastic wrap and freeze for up to three months.
Can I freeze the Tuxedo Cake?
Absolutely! To freeze the Tuxedo Cake without losing its luscious texture, slice it first. Wrap each slice individually in plastic wrap and place them in a ziplock bag or an airtight container. This helps prevent freezer burn. When you’re ready to enjoy, simply thaw in the refrigerator for a few hours.
What should I do if the mousse doesn’t set properly?
If your mousse doesn’t set, it may be because it wasn’t thickened enough during the cooking process. To troubleshoot, gently whisk the mousse over low heat, ensuring it reaches the correct consistency. Always remember to fold in the whipped cream gently to maintain the airiness, which is key to achieving that beautiful mousse texture.
Are there any dietary considerations for the Tuxedo Cake?
Yes, indeed! The Tuxedo Cake accommodates various dietary needs. To make it gluten-free, substitute all-purpose flour with an almond flour blend. For a dairy-free option, replace heavy cream with coconut cream and use dairy-free chocolates. You can also create a lighter version by reducing the sugar and substituting Greek yogurt for sour cream.
How do I prevent the mousse from separating?
To ensure your mousse stays beautifully blended, it’s critical to incorporate the whipped cream gently. Overmixing can lead to separation, so fold the whipped cream into the chocolate mixtures until just combined. Also, allow your mousses to cool before folding in the whipped cream, ensuring a perfect, airy texture!
