Step‑by‑Step Instructions for Tuxedo Bar Cake
Step 1: Preheat Oven and Prepare Pans
Preheat your oven to 350°F (175°C). While it heats, grease two 9-inch round cake pans or line them with parchment paper for effortless release. This preparation is crucial for uniform baking of your decadent Tuxedo Bar Cake, so be sure to cover the pans completely.
Step 2: Melt Butter and Cocoa
In a medium saucepan over medium heat, combine 1 cup of unsalted butter, 1 cup of water, and ¾ cup of unsweet dark cocoa powder. Stir continuously until the mixture is smooth and all components are melted together, about 5 minutes. This rich chocolate blend sets the foundation for your luscious cake.
Step 3: Mix Dry Ingredients
In a large mixing bowl, whisk together 2 ¾ cups of all-purpose flour, 2 cups of light brown sugar, 1 ½ teaspoons of baking soda, and 1 teaspoon of fine grain sea salt. If you’re using espresso powder, add that now as well. This dry mixture will provide structure and sweetness to your Tuxedo Bar Cake.
Step 4: Combine Wet and Dry Ingredients
Pour the melted butter and cocoa mixture into the bowl of dry ingredients. Stir gently until just combined. Avoid overmixing; you want a smooth batter without lumps, achieving a perfect consistency that will rise beautifully in the oven.
Step 5: Add Buttermilk and Eggs
Next, add 1 cup of buttermilk, 3 large eggs, and 2 teaspoons of vanilla extract to the batter. Beat the mixture until smooth, using a spatula or electric mixer. This will enrich the flavor and create a tender crumb for the Tuxedo Bar Cake.
Step 6: Bake the Cake Layers
Divide the batter evenly between the prepared cake pans. Bake in your preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean. The edges will start to pull away from the pan when perfectly baked, indicating it’s time to cool!
Step 7: Cool the Cake Layers
After baking, let the cakes cool in their pans for 10 minutes before transferring them to wire racks. Allow them to cool completely before assembling the Tuxedo Bar Cake. This step is crucial to avoid melting your mousse during assembly.
Step 8: Whip the Cream
In a mixing bowl, whip 2 cups of heavy cream until stiff peaks form. This should take about 3-4 minutes on medium speed. Gently fold in 1 cup of semisweet chocolate chips to create a light and airy mousse that will add delightful layers to your cake.
Step 9: Prepare Cream Cheese Layer
In another bowl, blend 8 ounces of cream cheese, 4 ounces of melted white chocolate, 1 cup of confectioners’ sugar, and 1 tablespoon of lemon juice until smooth. This creamy filling adds a delicious tanginess that balances the sweet layers of your Tuxedo Bar Cake.
Step 10: Assemble the Cake
On a serving platter, place one layer of chocolate cake and spread half of the chocolate mousse on top. Add the cream cheese layer next, followed by the second chocolate cake layer. Repeat the process with the remaining mousse for a towering Tuxedo Bar Cake.
Step 11: Make the Ganache
Heat 1 cup of semisweet chocolate chips, ½ cup of heavy cream, and 1 tablespoon of sunflower oil in a saucepan over low heat, stirring constantly until melted and smooth. Allow the ganache to cool slightly before pouring it over the assembled cake for a glossy finish.
Step 12: Decorate the Cake
Once the ganache has set, decorate the Tuxedo Bar Cake by piping chocolate buttercream around the base and on top. Finish it off with decorative rolled cookie wafers and fancy chocolate truffles. This final touch creates an irresistible presentation that will steal the show!

Expert Tips for Tuxedo Bar Cake
Use Room Temperature Ingredients: Start with room temperature butter, eggs, and buttermilk for easier mixing and a better cake texture.
Avoid Overmixing: Gently combine your ingredients to maintain a light and fluffy Tuxedo Bar Cake; overmixing can lead to dense layers.
Cool Completely: Ensure your cake layers are completely cooled before assembly to prevent the mousse from melting and losing its airy texture.
Stir Ganache Constantly: While making ganache, continuously stir over low heat to avoid burning and ensure a smooth consistency for a glossy finish.
Layer Creatively: Feel free to add extra layers of mousse or cream cheese mixture between cake layers for an even richer experience.
Consider Allergen Substitutes: Don’t forget you can easily adapt the recipe for gluten-free or dairy-free options, ensuring everyone can indulge in this delicious dessert!
How to Store and Freeze Tuxedo Bar Cake
Fridge: Store the Tuxedo Bar Cake in an airtight container in the fridge for up to 5 days. This keeps it moist and preserves the creamy layers.
Freezer: For longer storage, wrap the cake tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 3 months, maintaining its delicious flavors.
Thawing: When ready to enjoy, thaw the cake in the refrigerator overnight before serving. This gentle method preserves the texture and richness of the cake.
Reheating: If desired, slice individual pieces and microwave for about 10-15 seconds to warm slightly—enjoy the decadent chocolatey goodness!
Make Ahead Options
Preparing the Tuxedo Bar Cake in advance is a fantastic way to save time on busy baking days! You can bake the cake layers up to 3 days ahead and store them in an airtight container to keep them moist. Additionally, the chocolate mousse can be whipped up to 24 hours in advance; simply cover it tightly with plastic wrap and refrigerate. For the cream cheese filling, you can prepare that mixture up to 2 days ahead as well. When you’re ready to assemble, just layer the cooled cakes with the mousse and cream cheese filling, and finish off with the ganache. This way, you can enjoy a show-stopping dessert with minimal last-minute effort—just as delightful as making it fresh!

Tuxedo Bar Cake Recipe FAQs
How do I choose the right cocoa powder for my Tuxedo Bar Cake?
Absolutely! For the best flavor, I recommend using unsweetened dark cocoa powder. This type has a richer, more intense chocolate flavor that truly elevates your Tuxedo Bar Cake. Make sure it’s fresh—check the expiration date and avoid cocoa with dark spots, which may indicate staleness.
What is the best way to store my Tuxedo Bar Cake?
Very! The Tuxedo Bar Cake can be stored in an airtight container in the fridge for up to 5 days to keep it moist and delicious. If you want to keep it longer, wrap it tightly in plastic wrap and then in aluminum foil to freeze for up to 3 months. This will help maintain its flavor and texture while frozen.
Can I freeze the Tuxedo Bar Cake? How?
Of course you can! To freeze your Tuxedo Bar Cake, allow it to cool completely after baking and trimming. Wrap each layer individually in plastic wrap, then place them in an airtight container or a freezer bag to prevent freezer burn. When ready to enjoy, simply transfer the layers to the fridge overnight to thaw before assembling.
What should I do if my Tuxedo Bar Cake layers are too dense?
If your Tuxedo Bar Cake layers turn out dense, it might be due to overmixing or using cold ingredients. Make sure to mix just until combined and use room temperature ingredients for the best texture. If you prefer lighter layers, try separating and whisking the egg whites before folding them into the batter for added fluffiness!
Are there any dietary considerations for my Tuxedo Bar Cake?
Yes, indeed! For those with gluten sensitivities, you can easily swap out all-purpose flour for a gluten-free flour blend, ensuring everyone can enjoy this delightful dessert. Additionally, substitute the unsalted butter and buttermilk with dairy-free options for a lactose-friendly version. It’s all about accommodating different dietary needs and ensuring your Tuxedo Bar Cake remains delicious!
