Step‑by‑Step Instructions for Tuxedo Cake Recipe
Step 1: Preheat and Prepare Pans
Start by preheating your oven to 350°F (175°C). While it heats, grab two 8-inch round cake pans, greasing them with butter or cooking spray. Dust each pan with flour, ensuring an even coating to prevent sticking. This preparation ensures your Tuxedo Cake comes out perfectly shaped and ready for its delicious layers.
Step 2: Make Cake Batter
In a large mixing bowl, sift together all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. In a separate bowl, mix together the wet ingredients: buttermilk, vegetable oil, eggs, and vanilla extract. Gradually incorporate the dry mix into the wet mixture, stirring until smooth. Finally, add boiling water to the batter, allowing it to thin out, creating a rich chocolatey base.
Step 3: Bake Cake
Evenly divide the batter between the prepared pans, using a spatula to smooth the tops. Bake the cakes in your preheated oven for 35-40 minutes, or until a toothpick inserted in the center comes out clean. Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes before transferring them to wire racks to cool completely.
Step 4: Prepare Dark Chocolate Mousse
For the dark chocolate mousse, begin by melting semi-sweet chocolate and unsalted butter together in a heatproof bowl over simmering water. In another bowl, whisk egg yolks until pale, then set aside. Whip heavy cream and egg whites separately until they form stiff peaks. Fold the chocolate mixture with the egg yolks, then gently incorporate the whipped cream and egg whites, keeping the airy texture intact. Refrigerate until ready to layer in your Tuxedo Cake.
Step 5: Prepare White Chocolate Mousse
Using the same method as the dark mousse, melt white chocolate with butter over simmering water. Whisk egg yolks in a bowl, then set aside. Prepare another bowl of whipped cream and egg whites. Combine the melted white chocolate with the yolks, then fold in the whipped cream and egg whites. This airy white chocolate mousse will perfectly complement the dark layers of your Tuxedo Cake.
Step 6: Make Ganache
In a small saucepan, heat heavy cream until just about to simmer, then pour it over chopped semi-sweet chocolate in a bowl. Let it sit for a few minutes to melt the chocolate, then stir until smooth and glossy. Allow the ganache to cool until it reaches a spreadable consistency, ensuring it’s ready to adorn your Tuxedo Cake beautifully.
Step 7: Assemble Cake
Once the cakes are completely cooled, carefully slice each into two horizontal layers. Start with a layer of chocolate cake and spread a generous amount of dark chocolate mousse on top. Add the next layer, repeat with white chocolate mousse, and continue layering until all the cakes and mousse are used. Finally, top the entire cake with the delicious ganache for a glossy, elegant finish.
Step 8: Chill
After assembling the Tuxedo Cake, cover it loosely with plastic wrap and place it in the refrigerator. Allow it to chill for at least 60 minutes, or longer if desired, so the flavors meld and the mousse firms up. This step is crucial for achieving that perfect slice when serving your decadent cake to friends and family.
Step 9: Decorate
Once the Tuxedo Cake has chilled, it’s time to get creative! Use the remaining ganache to create decorative drizzles on top, and consider adding chocolate shavings or curls for an eye-catching finish. This final touch not only enhances the visual appeal but perfectly complements the rich flavors of the cake.

Make Ahead Options
This Tuxedo Cake Recipe is perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the chocolate cake layers up to 24 hours in advance; just let them cool completely before wrapping them in plastic wrap and refrigerating to keep them moist. Both the dark and white chocolate mousse can also be made ahead and stored in the fridge for up to 3 days. Just remember to cover them tightly to prevent browning and maintain their lovely texture. When you’re ready to serve, assemble the cake with the chilled layers and mousse, finish with ganache, and let it set for at least 60 minutes in the refrigerator for that perfect slice. Enjoy effortless indulgence with this beloved chocolate dessert!

Tuxedo Cake Recipe FAQs
How do I choose ripe ingredients for the Tuxedo Cake?
Absolutely! For the best results, ensure your eggs are fresh (check the expiration date) and your cocoa powder is unsweetened and fresh. If using buttermilk, pick a brand that is creamy and not close to its expiration date for maximum moisture. For chocolate, always opt for high-quality brands – the taste of your cake greatly depends on it!
What’s the best way to store leftover Tuxedo Cake?
To keep your Tuxedo Cake fresh, store any leftovers in an airtight container in the refrigerator for up to 3 days. Make sure to separate layers with parchment paper to prevent them from sticking together. This method helps maintain that creamy mousse structure and prevents it from drying out.
Can I freeze Tuxedo Cake?
Yes, you can freeze Tuxedo Cake! First, wrap individual slices tightly in plastic wrap, then place the wrapped slices in an airtight container or a zip-top bag to prevent freezer burn. Freeze for up to 2 months. When you’re ready to enjoy a slice, simply transfer it to the refrigerator the night before to thaw while retaining its delightful texture.
What should I do if my mousse is too runny?
If your mousse is not setting properly, there are a few steps you can take. First, ensure that the chocolate was properly melted and cooled before mixing it with the egg yolks and cream. If it remains too thin, you might need to whip in a bit more cream until stiff peaks form or refrigerate the mousse longer. If time permits, resetting the mousse in the refrigerator should help.
Are there any dietary considerations I should keep in mind for this cake?
Very! If someone has a gluten intolerance, simply substitute all-purpose flour with a gluten-free flour blend to make this Tuxedo Cake recipe suitable for everyone. Additionally, for those with egg allergies, you can experiment with egg replacers like flaxseed meal mixed with water or unsweetened applesauce, though the texture may vary slightly.
Can I use any chocolate instead of semi-sweet chocolate in the mousse?
The more the merrier when it comes to flavors! You can swap out semi-sweet chocolate for milk chocolate if you prefer a sweeter taste. However, dark chocolate gives a more intense flavor that balances the sweetness of the white chocolate mousse perfectly. Just be mindful to adjust the sugar content in your mousse accordingly if you’re using a sweeter chocolate.
