Step‑by‑Step Instructions for Decadent Tuxedo Bar Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, prepare two 9-inch round cake pans by greasing them with butter or lining the bottoms with parchment paper for easy cake removal. This simple step sets the foundation for achieving a perfectly baked Decadent Tuxedo Bar Cake.
Step 2: Melt Butter and Cocoa
In a medium saucepan over low heat, combine ½ cup of unsalted butter, 1 cup of water, and ¾ cup of unsweet dark cocoa powder. Stir continuously until the mixture is completely melted and smooth, then remove it from the heat and allow it to cool slightly. This rich chocolate mixture will be the heart of your cake’s flavor.
Step 3: Combine Dry Ingredients
In a large mixing bowl, whisk together 1 ¾ cups of all-purpose flour, 1 cup of light brown sugar, 1 teaspoon of baking soda, and ½ teaspoon of fine grain sea salt. If you’re using espresso powder for an enhanced chocolate flavor, fold it in now. This mixture provides the necessary structure for your Tuxedo Bar Cake.
Step 4: Mix Wet and Dry Ingredients
Once the butter-cocoa mixture has cooled, pour it into the bowl with the dry ingredients. Gently mix with a spatula until just combined, ensuring not to overmix. The batter should be smooth and slightly thick, ready to deliver a rich, moist cake.
Step 5: Add Buttermilk and Eggs
Incorporate 1 cup of buttermilk, 2 large eggs, and 2 teaspoons of vanilla extract into the batter. Mix gently until the ingredients are thoroughly combined, creating a beautiful, velvety texture. This step adds moistness and flavor to the cake, perfecting the profile of your Decadent Tuxedo Bar Cake.
Step 6: Bake the Cake
Divide the batter evenly between the prepared pans. Place them in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. The cakes should have risen and the tops should look slightly domed indicating they are done.
Step 7: Cool the Cake
Once baked, remove the cake pans from the oven and allow them to cool in the pans for about 10 minutes. Then, gently turn the cakes out onto a wire rack to cool completely. Proper cooling is essential before assembly, ensuring that the luscious mousse doesn’t melt when layered.
Step 8: Whip Cream
While the cakes are cooling, pour 1 ½ cups of heavy cream into a mixing bowl. Using an electric mixer, whip the cream on high speed until stiff peaks form, which should take about 3-5 minutes. This whipped cream will help create an airy mousse that complements the rich layers of your Tuxedo Bar Cake.
Step 9: Prepare Cream Cheese Mixture
In a separate bowl, blend 8 oz of cream cheese, ½ cup of melted white chocolate, ½ cup of confectioners’ sugar, and 2 tablespoons of softened butter until smooth. If desired, add a splash of lemon juice for brightness. This creamy mixture adds a tangy balance to the chocolate layers.
Step 10: Assemble Layers
Once the cakes are completely cooled, place one layer on a serving platter. Spread half of the whipped cream mixture over the cake, followed by half of the cream cheese mixture. Place the second cake layer on top and repeat the process with the remaining mousse and cream cheese mixture. This layered assembly creates the signature allure of the Decadent Tuxedo Bar Cake.
Step 11: Make Ganache
For a glossy finish, combine 1 ½ cups of semisweet chocolate chips with ¾ cup of heavy cream and 2 tablespoons of sunflower oil in a microwave-safe bowl. Heat in 30-second increments, stirring in between until smooth and well combined. Once ready, pour the ganache over the assembled cake, allowing it to drip down the sides beautifully.
Step 12: Decorate
Finally, pipe some frosting or ganache around the base of the cake and add a few rolled cookie wafers and fancy chocolate truffles on top for decoration. These finishing touches will not only enhance the visual appeal of your Decadent Tuxedo Bar Cake but also create an indulgent experience that’s simply irresistible.

Make Ahead Options
These Decadent Tuxedo Bar Cakes are perfect for busy home cooks looking to streamline their dessert preparations! You can bake the cake layers up to 3 days in advance. Once cooled, wrap them tightly in plastic wrap and store in the refrigerator to keep them moist. Additionally, the mousse and cream cheese mixture can be prepared 24 hours ahead and stored in the fridge, ensuring that the flavors meld beautifully. Just remember to assemble the layers right before serving to maintain that light, airy texture. When you’re ready to enjoy, simply pour the ganache over the assembled cake, and you’ve got a stunning delight, ready to impress with minimal effort!

Decadent Tuxedo Bar Cake Recipe FAQs
What kind of cocoa powder should I use for the cake?
For the richest flavor, I recommend using unsweet dark cocoa powder. It creates a deep, chocolatey taste that makes your Decadent Tuxedo Bar Cake simply irresistible! If you prefer something milder, regular cocoa powder can also be used, but the cake’s flavor will be less intense.
Can I store the cake at room temperature?
Absolutely! While you can leave your Decadent Tuxedo Bar Cake at room temperature for a day, it’s best to refrigerate it to maintain its delicious layers. Wrap any leftovers in plastic wrap and keep them in an airtight container for up to 5 days.
How do I freeze leftover cake slices?
To freeze, cut your Decadent Tuxedo Bar Cake into individual slices. Wrap each slice tightly in plastic wrap, then place them in a freezer-safe container or bag. They can be frozen for up to 3 months. When you’re ready to enjoy, simply take a slice out and let it thaw in the refrigerator, or microwave it for 10-15 seconds for a quick warm-up!
What can I use as substitutes for dairy ingredients?
If you’re looking to make the cake dairy-free, you can easily substitute non-dairy butter and cream cheese alternatives in the recipe. Additionally, for buttermilk, you can use almond milk mixed with a tablespoon of vinegar or lemon juice. This way, everyone gets to indulge in the deliciousness of your Tuxedo Bar Cake!
What should I do if my cake layers turn out dense?
If your cake layers are dense, it may be due to overmixing the batter or improper measuring of ingredients. Make sure to mix just until combined and use a kitchen scale to accurately weigh dry ingredients. Also, remember that all your ingredients, especially eggs and buttermilk, should be at room temperature for the best results!
How do I know when my cake is done baking?
Check for doneness by inserting a toothpick into the center of the cake. If it comes out clean or with a few moist crumbs, your Decadent Tuxedo Bar Cake is ready! Remember, baking times can vary, so keep an eye on your cake after 30 minutes.
