Step‑by‑Step Instructions for Tuxedo Bar Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). Prepare two 9-inch round cake pans by greasing them with butter or lining them with parchment paper. This will ensure your Tuxedo Bar Cake layers come out easily and unblemished after baking, ensuring a beautiful presentation.
Step 2: Melt the Chocolate Mixture
In a medium saucepan, combine the unsalted butter, water, and unsweetened dark cocoa powder over medium heat. Stir continuously until the mixture is melted and smooth, then remove it from the heat and allow it to cool for about 10 minutes. This mixture provides the rich, chocolatey base for your cake.
Step 3: Mix the Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, light brown sugar, baking soda, fine grain sea salt, and espresso powder, if using. Make sure everything is well combined to ensure an even distribution of flavors and textures in your Tuxedo Bar Cake.
Step 4: Combine Wet and Dry Mixtures
Gently fold the cooled chocolate mixture into the bowl of dry ingredients using a spatula or wooden spoon. Mix until just combined to avoid overworking the batter, which can lead to a dense cake. The batter should be smooth and rich, showcasing its decadent chocolate flavor.
Step 5: Add the Remaining Ingredients
Next, add the buttermilk, eggs, and vanilla extract to the batter, mixing until smooth and fully combined. You can employ a hand mixer on low speed if preferred, but be cautious not to overmix. The batter will be thick and glossy, ready for the cake pans.
Step 6: Bake the Cakes
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 into the center comes out clean. The cakes should rise beautifully and have a slight bounce when gently pressed.
Step 7: Cool the Cakes
Allow the cakes to cool in the pans for about 10 minutes. Carefully run a knife around the edges and transfer them to wire racks to cool completely. This step is crucial to prevent melting the mousse during assembly, ensuring your Tuxedo Bar Cake layers are set.
Step 8: Prepare the Mousse
In a mixing bowl, whip heavy cream until stiff peaks form. Then fold in the semisweet chocolate chips gently until well combined. This airy mousse will provide a delightful texture between the layers of your cake, offering a rich chocolate experience.
Step 9: Blend the Cream Cheese Mixture
In another bowl, blend cream cheese, white chocolate, confectioners’ sugar, and softened butter until smooth and creamy. This mixture adds a tangy contrast to the rich chocolate flavors of your Tuxedo Bar Cake and creates a luscious layer of creaminess.
Step 10: Assemble the Layers
Once the cake layers are completely cool, place one layer on a serving platter. Spread half of the chocolate mousse over it, followed by half of the cream cheese mixture. Top with the second cake layer and repeat the process, ensuring each layer is even and beautifully stacked.
Step 11: Make the Ganache
For the ganache, melt the semisweet chocolate chips, heavy cream, and sunflower oil together in a saucepan over low heat. Stir continuously until smooth and glossy, then pour the ganache over the top of your assembled Tuxedo Bar Cake. Allow it to drip down the sides for a luxurious finish.
Step 12: Decorate and Serve
Finally, decorate your Tuxedo Bar Cake with additional frosting, chocolate truffles, and rolled cookie wafers as desired. Let it set for a moment before slicing. Enjoy the beautiful layers and flavors of this indulgent dessert with friends and family!

Tuxedo Bar Cake Recipe FAQs
What type of cocoa powder should I use for the Tuxedo Bar Cake?
I recommend using unsweet dark cocoa powder for a rich, deep chocolate flavor. If you prefer a slightly milder taste, you could use Dutch-processed cocoa powder, which has a more mellow and smooth profile.
How long can I store the Tuxedo Bar Cake?
Cover and refrigerate the cake to keep it fresh for up to 3 days. If you want to keep it longer, individual slices can be wrapped tightly in plastic wrap and frozen for up to 3 months. Simply let them thaw in the fridge overnight when you’re ready to enjoy!
Can I make the Tuxedo Bar Cake dairy-free or gluten-free?
Absolutely! For a dairy-free version, substitute the unsalted butter with dairy-free butter, and replace the buttermilk with a dairy-free milk mixed with vinegar. To make it gluten-free, just swap the all-purpose flour for a gluten-free blend, ensuring it contains a binding agent like xanthan gum.
What should I do if my ganache doesn’t come out smooth?
If your ganache is grainy or separates, it’s typically due to the chocolate overheating. To fix it, try adding a tablespoon of hot heavy cream to the ganache while whisking continuously until smooth. If it still won’t come together, you can also try blending it with an immersion blender to achieve a silky finish.
What’s the best way to decorate my Tuxedo Bar Cake?
To decorate, consider using a mix of additional whipped cream, chocolate truffles, and rolled cookie wafers on top. You can also drizzle some extra ganache over the sides for a luxurious look. Get creative! The more, the merrier when it comes to presentation!
Can I add fresh fruit to the Tuxedo Bar Cake?
Yes, layering fresh berries or slices of fruit between the cake layers can add a refreshing twist! Just be mindful of the moisture they can add, which may slightly alter the texture of the cake; it’s usually best to use them sparingly.
