Step‑by‑Step Instructions for Tuxedo Cake – Triple Chocolate Mousse Cake
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) while you prepare two 9-inch round cake pans. Grease the pans thoroughly and line the bottoms with parchment paper. This ensures that the Tuxedo Cake layers release easily and maintain their perfect shape once baked.
Step 2: Whisk the Dry Ingredients
In a large mixing bowl, combine the all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. Whisk together until all the dry ingredients are evenly blended. This step is vital for a uniform texture in your cake layers, leading to a deliciously balanced Tuxedo Cake.
Step 3: Mix the Wet Ingredients
In a separate bowl, whisk together the eggs, whole milk, sour cream, vegetable oil, espresso powder, and vanilla extract until smooth. Stirring these ingredients thoroughly ensures a rich and moist batter. This mixture will bring life and flavor to your Tuxedo Cake.
Step 4: Combine Wet and Dry Ingredients
Gently fold the wet ingredients into the dry mixture using a spatula, being careful not to overmix. Gradually pour in the hot water while stirring until the batter is smooth and well combined. The hot water aids in developing a tender crumb, contributing flavor to your Tuxedo Cake.
Step 5: Bake the Cake Layers
Divide the batter evenly between the prepared cake pans. Place them in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on the layers, as you want them light and fluffy, perfect for your Tuxedo Cake.
Step 6: Cool the Cake Layers
Once baked, remove the cakes from the oven and let them cool in the pans for 10 minutes. Afterward, gently transfer the layers to wire racks and allow them to cool completely for about 2 hours. Cooling is essential before assembling the Tuxedo Cake to prevent any melting of the mousse.
Step 7: Prepare the Chocolate Mousses
In a saucepan, heat 1 cup of heavy cream over medium heat until it begins to simmer. In another bowl, whisk together the egg yolks, sugar, and cornstarch until fully combined. Once the cream is simmering, whisk it into the egg mixture to create a custard base for the mousses.
Step 8: Incorporate Chocolate into Mousses
Divide the custard mixture into two separate bowls. In one bowl, add the melted dark chocolate and mix until smooth. In the other bowl, fold in the melted white chocolate. This chocolate infusion creates the rich textures in both mousses for your Tuxedo Cake.
Step 9: Fold in the Cream
Gently fold whipped heavy cream into each chocolate mixture, ensuring not to deflate the airiness. The dark mousse will be richer, while the white mousse will provide a delightful contrast, contributing to the layers in your Tuxedo Cake.
Step 10: Assemble the Cake
Place one cooled cake layer on a serving plate and gently spread a layer of dark chocolate mousse on top. Add the second cake layer and cover it generously with the white chocolate mousse. This layering builds the luxurious profile of the Tuxedo Cake, essential for its signature look.
Step 11: Chill to Set
Cover the assembled Tuxedo Cake with plastic wrap and refrigerate for at least 2 hours. Chilling allows the mousses to firm up, creating the decadent texture that makes this dessert so special.
Step 12: Make the Ganache
To create the ganache, heat 1 cup of heavy cream until it’s hot but not boiling. Pour it over the chopped milk chocolate and stir until smooth and glossy. Let the ganache cool for about 5 minutes, achieving the perfect pouring consistency for your Tuxedo Cake.
Step 13: Finish and Serve
Pour the ganache over the chilled cake, allowing it to elegantly drip down the sides. Return the cake to the refrigerator for an additional 30 minutes. When ready to serve, slice and enjoy the glorious layers of the Tuxedo Cake – Triple Chocolate Mousse Cake with friends and family.

Expert Tips for Tuxedo Cake

Tuxedo Cake – Triple Chocolate Mousse Cake Recipe FAQs
How do I choose the right ripeness of ingredients, especially chocolate?
Absolutely! When selecting chocolate for your Tuxedo Cake, choose high-quality chocolate with no visible signs of bloom (a white coating), which could indicate age. For cocoa powder, make sure it is unsweetened and fresh; it should have a rich, robust aroma, ensuring maximum flavor in your dessert.
How should I store my Tuxedo Cake after it’s assembled?
Store the assembled Tuxedo Cake in the refrigerator for up to 2 days. Cover it with plastic wrap, making sure it touches the mousse. This prevents a skin from forming and keeps it fresh. If you want to make it ahead, you can assemble it a day in advance for convenience, letting the flavors meld beautifully.
Can I freeze the Tuxedo Cake, and if so, how?
Absolutely! Freezing is a great option. After chilling the cake, slice it into individual portions and wrap each slice tightly in plastic wrap and then in foil. This helps prevent freezer burn. The Tuxedo Cake can be frozen for up to three months. When you’re ready to enjoy, simply thaw it in the fridge overnight for the best texture before serving.
What can I do if my cake layers sink in the middle?
Very good question! A sunken cake often means it was underbaked or the oven temperature wasn’t accurate. Ensure your oven is preheated and consider using an oven thermometer for accuracy. Check doneness with a toothpick; if it comes out clean, your cake is ready. If you experience sinking again, check the freshness of your baking powder and soda, as old leavening agents can affect rise.
Are there any dietary considerations I should keep in mind?
The Tuxedo Cake is versatile! For those with gluten sensitivities, substitute all-purpose flour with an almond flour blend. For a dairy-free option, swap the heavy cream with coconut cream and use dairy-free chocolates in the mousse. If you’re vegan, consider using flax eggs instead of large eggs.
