• Granulated Sugar – Adds sweetness and moisture to the cake.
• Dutch-Processed Dark Cocoa Powder – Contributes rich flavor and deep color; regular cocoa powder can be used for a lighter result, though flavor will be less intense.

• Salt – Enhances flavor and balances the sweetness of the cake.
• Unsalted Butter – Binds the ingredients and adds richness; ensure butter is at room temperature for easy mixing.
• Egg Whites – Provide structure and moisture; approximately 7 large, at room temperature is ideal.
• Buttermilk – Adds moisture and tenderness; Greek yogurt thinned with milk can be used in a pinch.
• Vegetable Oil – Contributes additional moisture and richness to the cake.
• Vanilla Extract – Elevates the overall flavor profile of the cake.
• Instant Espresso (optional) – Intensifies the chocolate flavor without imparting a coffee taste.
For the Mousses
• White Chocolate Chips – Used for the white chocolate mousse; ensure quality for best results.
• Heavy Cream – Vital for creating the mousses and ganache; must be well-chilled for optimal whipping.
• Powdered Sugar – Sweetens the mousses to enhance flavor.
• Dark Chocolate Chips – The main ingredient in dark chocolate mousse and ganache; use high-quality chocolate for the best flavor.
• Light Corn Syrup – Helps achieve a glossy texture in the ganache.
• Pinch of Salt – Used in both mousse and ganache to balance flavors effectively.
This carefully curated selection of ingredients will transform your baking into a symphony of textures and flavors, making your perfect Chocolate Tuxedo Cake a guaranteed hit!
Step‑by‑Step Instructions for Perfect Chocolate Tuxedo Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease two 9-inch round cake pans with butter, then line the bottoms with parchment paper for easy removal. This ensures your layers bake evenly and release flawlessly, setting the stage for your perfect Chocolate Tuxedo Cake.
Step 2: Combine Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, Dutch-processed cocoa powder, baking powder, and salt until well blended. This dry mixture serves as the foundation for your cake, giving it structure and flavor. Make sure there are no lumps, as this will lead to a smooth, rich batter.
Step 3: Mix Wet Ingredients
In a separate bowl, blend the room temperature unsalted butter, egg whites, buttermilk, vegetable oil, vanilla extract, and optional instant espresso until the mixture is smooth and creamy. Using an electric mixer can help incorporate air into the batter, enhancing the moisture of the perfect Chocolate Tuxedo Cake for a light texture.
Step 4: Combine Mixtures and Bake
Gradually add the wet ingredients to the dry mixture, gently folding until just combined. Avoid overmixing to keep the cake tender. Divide the batter evenly between the prepared cake pans and smooth the tops. Bake in the preheated oven for 30-35 minutes or until a toothpick inserted in the center comes out clean.
Step 5: Cool the Cakes
Once baked, allow the cake layers to cool in the pans for about 10 minutes. Then, carefully transfer them to wire racks to cool completely. This step is crucial to ensure the layers hold their shape as you assemble your perfect Chocolate Tuxedo Cake later.
Step 6: Prepare the White Chocolate Mousse
For the white chocolate mousse, melt the white chocolate chips with half of the warm water in a double boiler over low heat, stirring until smooth. Allow it to cool slightly. Whip the heavy cream with powdered sugar in a chilled bowl until soft peaks form, then fold in the cooled chocolate mixture. Chill the mousse for at least 2 hours to achieve the right consistency.
Step 7: Make the Dark Chocolate Mousse
Next, for the dark chocolate mousse, repeat the melting process with the dark chocolate chips and the remaining warm water. Let it cool for a bit. Whip another batch of heavy cream with powdered sugar until soft peaks form, then carefully fold in the melted dark chocolate. Chill this mixture for a minimum of 2 hours as well.
Step 8: Create the Ganache
To make the ganache, heat 1 cup of heavy cream in a saucepan until it reaches a simmer. Pour this over the dark chocolate chips in a bowl, letting it sit for a few minutes before stirring until smooth. Add in the butter, light corn syrup, and a pinch of salt, mixing until well combined. Cool until it reaches a pourable consistency.
Step 9: Assemble the Cake
Once the cake layers are cooled, use a serrated knife to level the tops. Place one layer on a serving plate or cake stand and spread a generous layer of white chocolate mousse on top. Place the second layer on top and add a layer of dark chocolate mousse, smoothing it evenly for a decadent finish.
Step 10: Final Layer and Ganache
Add the third layer on top, then pour the prepared ganache over the entire cake, allowing it to drizzle down the sides for a beautiful effect. Chill the assembled cake for at least 1 hour to firm up the mousse and ganache, preparing your perfect Chocolate Tuxedo Cake for slicing.
Step 11: Slice and Serve
When ready to serve, use a hot knife to slice through the cake for clean cuts, revealing the beautiful layers of mousses and cake. This ensures every piece looks as delightful as it tastes, making each serving of your perfect Chocolate Tuxedo Cake a memorable bite.
Make Ahead Options
Preparing your perfect Chocolate Tuxedo Cake in advance is a game-changer for busy cooks! You can bake the cake layers up to 24 hours ahead. Once cooled, wrap them tightly in plastic wrap and refrigerate to keep them moist. Both the white and dark chocolate mousses can be made up to 3 days in advance; store them in airtight containers in the refrigerator to maintain their fluffy texture. When you’re ready to indulge, simply assemble the cake and pour the ganache over it, allowing it to chill for at least 1 hour before slicing. This way, you’ll have a stress-free dessert that tastes just as delicious and fresh as if made the same day!
How to Store and Freeze Perfect Chocolate Tuxedo Cake
Fridge: Store the assembled perfect Chocolate Tuxedo Cake in the refrigerator for up to 4 days. Cover it with plastic wrap or a cake dome to prevent it from absorbing other odors.
Freezer: For longer storage, wrap slices individually in plastic wrap and then in aluminum foil. The cake can be frozen for up to 6 weeks. Thaw overnight in the refrigerator before serving.
Room Temperature: Avoid leaving the cake out at room temperature for more than 2 hours to ensure food safety, especially if the room is warm.
Reheating: If you want to serve warm, heat individual slices in the microwave for about 10-15 seconds. This will slightly melt the mousses, enhancing the indulgence!
Perfect Chocolate Tuxedo Cake Variations
Feel free to unleash your creativity and personalize this cake to suit your tastes or dietary preferences!
- Gluten-Free: Swap all-purpose flour for a 1-for-1 gluten-free flour blend, making it accessible for everyone to enjoy.
- Milk Alternative: Use almond or oat milk instead of buttermilk for a dairy-free alternative. This will still keep the cake moist and flavorful.
- Flavor Infusion: Add a tablespoon of flavored extract, such as orange or almond, to the batter for a delightful twist that elevates the chocolaty goodness.

Expert Tips for Perfect Chocolate Tuxedo Cake
• Chill Your Tools: Ensure your mixing bowls and beaters are chilled for 20 minutes before whipping cream; this helps achieve stable, voluminous mousses.
• Clean Cuts: Use a long, sharp serrated knife for cutting the cake layers. Clean the blade between cuts for elegant slices that showcase your perfect Chocolate Tuxedo Cake.
• Cooling Time: Allow cake layers to cool completely before assembly; if needed, chill them in the freezer for about 15 minutes for easier handling.
• Ganache Consistency: Make sure your ganache reaches a pourable consistency. If it’s too thick, gently reheat and stir in a little extra cream to ensure the right texture.
• Layering Technique: When assembling your cake, spread mousse evenly to avoid sliding layers. Layering cramped mousses makes them less likely to ooze out when sliced.
Perfect Chocolate Tuxedo Cake Recipe FAQs
How do I choose the right flour for the Perfect Chocolate Tuxedo Cake?
Absolutely! For the best results, use all-purpose flour, as it provides the structure for the cake. If you’re looking to make it gluten-free, substitute with a 1-for-1 gluten-free flour blend, which works beautifully without sacrificing taste.
What is the best way to store the Perfect Chocolate Tuxedo Cake?
The assembled cake can be stored in the refrigerator for up to 4 days. Make sure to cover it with plastic wrap or a cake dome to keep it fresh and prevent it from absorbing other odors. If you have any leftover slices, they can be individually wrapped and stored in the freezer for up to 6 weeks.
Can I freeze the Perfect Chocolate Tuxedo Cake?
Yes, you can! Wrap each slice tightly in plastic wrap, then again in aluminum foil to prevent freezer burn, and freeze for up to 6 weeks. When you’re ready to enjoy a slice, simply thaw it overnight in the refrigerator. This method helps preserve the cake’s flavor and texture beautifully.
What if my mousse turns out too runny?
Very! If your mousses are too runny, it’s likely they haven’t been chilled enough or the cream wasn’t whipped to soft peaks. Ensure your mixing bowls and beaters are chilled before whipping heavy cream. If you need to salvage a runny mousse, you can whip additional cream and fold it in to add volume and stability.
Are there any allergies I should be aware of when making this cake?
Definitely! The Perfect Chocolate Tuxedo Cake contains common allergens such as dairy (in the butter, buttermilk, and cream) and eggs. For a dairy-free version, consider using plant-based alternatives for butter, milk, and cream. If you’re making it for someone with an egg allergy, egg replacers can be used, but the texture may vary.
How can I ensure clean cuts when slicing the Perfect Chocolate Tuxedo Cake?
Certainly! Use a long, sharp serrated knife to slice the cake. To achieve clean cuts, dip the knife in hot water, wipe it dry, and cut through the cake. This method prevents the mousses from sticking to the knife, allowing the beautiful layers of your perfect Chocolate Tuxedo Cake to shine through!
