Ingredients
For the Cake:

- 2 cups (400g) granulated sugar
- ½ cup (50g) cocoa powder
- 1½ teaspoons baking powder
- 1½ teaspoons baking soda
- ½ teaspoon salt
- ½ cup (120ml) whole milk, at room temperature
- 2 large eggs, at room temperature
- ½ cup (128g) sour cream, at room temperature
- ½ cup (110g) vegetable oil
- 1 teaspoon espresso powder (optional, amplifies the chocolate flavor)
- 1 teaspoon vanilla extract
- 1 cup (240ml) hot water
For the Chocolate Mousse:
- 4 large egg yolks
- 2 cups (480ml) heavy cream
- 2 tablespoons granulated sugar
- 2 tablespoons cornstarch
- 1 teaspoon vanilla extract
- 3.5 oz (100g) dark chocolate, chopped
- 4.5 oz (130g) white chocolate, chopped
- 5 oz (140g) milk chocolate, chopped
- ⅓ cup (80ml) heavy cream (for ganache)
Ingredient Quality and Substitutions
- Chocolate: High-quality chocolate like Callebaut or Ghirardelli will elevate the flavor. Chocolate chips can also be used if you’re in a pinch but avoid cheap brands.
- Room Temperature Ingredients: Make sure your eggs, milk, and sour cream are at room temperature for the best texture.
Step-by-Step Instructions
Preheat and Prepare: Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans. For easy removal, I always line the bottoms with parchment paper.
Mix Dry Ingredients: In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt until well combined.
Combine Wet Ingredients: In a separate bowl, combine milk, eggs, sour cream, vegetable oil, espresso powder, and vanilla extract. I whisk these wet ingredients thoroughly to ensure the espresso dissolves completely.
Combine Wet and Dry Ingredients: Gradually add the wet ingredients to the dry ingredients, mixing until just combined. The batter will look thick at this point.
Add Hot Water: Slowly stir in the hot water until the batter is smooth and thin. Don’t worry—this thin consistency is exactly what creates the cake’s tender crumb.
Bake: Divide the batter evenly between the prepared pans and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
Cool: Cool the cakes in their pans for 10 minutes, then turn out onto wire racks to cool completely. I always let them cool for at least 2 hours before assembling.
Make Chocolate Mousses:
- Heat 1 cup of heavy cream in a saucepan until it just begins to simmer. Remove from heat immediately.
- In a bowl, whisk egg yolks with sugar and cornstarch until pale and thick. Slowly pour the hot cream into the yolk mixture, whisking constantly to prevent curdling.
- Return the mixture to the saucepan and cook over medium heat, stirring constantly, until it thickens enough to coat the back of a spoon (about 2-3 minutes).
Chocolate Creation:
- Divide this custard base equally between two bowls. Add the dark chocolate to one bowl and white chocolate to the other, stirring until completely melted and smooth.
Whip and Fold: Beat the remaining 1 cup of heavy cream to soft peaks. Fold half of it into each chocolate mixture to create two distinct mousses.
Assemble:
- Place one cake layer on your serving plate. Spread the dark chocolate mousse evenly over the top, then add the second cake layer.
- Spread the white chocolate mousse over the top layer, creating smooth, even coverage. Refrigerate for at least 2 hours to set.
- Ganache Topping:
- For the ganache, heat the heavy cream until it just begins to simmer, then pour over the milk chocolate. Let sit for 2 minutes, then stir until smooth and glossy.
- Pour the ganache over the chilled cake, allowing it to drip down the sides for that classic tuxedo effect. Refrigerate for another 30 minutes before serving.
Expert Tips & Tricks
- Storage Recommendations: Tuxedo Cake can be stored in the refrigerator for up to 3 days, but I doubt it will last that long!
- Make-Ahead: You can bake the cake layers a day in advance and the mousses the day before assembly for reduced stress.
- Common Mistakes to Avoid: Ensure ingredients are at room temperature to prevent curdling and ensure a smooth batter and mousse.
- Troubleshooting:
- Mousses Not Setting: If your mousse doesn’t seem to firm up, it may need more time in the refrigerator due to warmer kitchen temperatures or incorrect measuring.
Serving Suggestions
Pair your Tuxedo Cake with a dollop of whipped cream or a scoop of vanilla ice cream to elevate its indulgence. For special occasions, garnish with fresh berries or edible flowers for a stunning presentation. This cake is perfect for celebrations, dinner parties, or even a cozy night in with loved ones!
Variations & Substitutions
- Flavor Combinations: Try adding a raspberry or orange zest to the chocolate mousse for a fruitier take or switch up the espresso powder for a touch of cinnamon.
- Dietary Restrictions: Gluten-free flour can be substituted to cater to gluten sensitivities, and non-dairy creams will work for lactose-intolerant guests.
- Seasonal Variations: Consider infusing the mousse with seasonal flavors such as peppermint for the winter holidays or lemon for springtime celebrations.
