- ¼ cup (50g) granulated sugar
White Chocolate Mousse
- 200g white chocolate, finely chopped
- 3 large egg yolks

Instructions
- Prepare the Chocolate Cake Layers: Preheat your oven to 350°F (175°C) and grease and flour two 8-inch round cake pans to prevent sticking.
- Mix Dry Ingredients: In a large bowl, sift together the flour, granulated sugar, Dutch-process cocoa powder, baking powder, baking soda, and salt to ensure even distribution.
- Add Wet Ingredients: Incorporate the milk, eggs, sour cream, vegetable oil, espresso powder (if using), and vanilla extract into the dry ingredients. Mix just until combined, being careful not to overmix.
- Incorporate Hot Water: Stir in the hot water carefully until the batter is smooth; the batter will be thin, which is normal for this cake.
- Bake the Cake Layers: Evenly divide the batter between the two prepared pans and bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
- Cool Cake Layers: Allow the cakes to cool in their pans for 10 minutes before transferring them to wire racks to cool completely, preventing sogginess.
- Prepare Dark Chocolate Mousse: Melt the dark chocolate using a double boiler or microwave, then let it cool slightly to avoid cooking the eggs later.
- Mix Egg Yolks and Sugar: Whisk the egg yolks and sugar together until the mixture becomes pale and slightly thickened.
- Combine Cream and Eggs: Heat the heavy cream until warm but not boiling, and slowly pour it over the egg yolk mixture while whisking continuously to temper the eggs.
- Add Melted Chocolate: Stir the melted dark chocolate into the cream and egg mixture until thoroughly combined.
- Fold in Whipped Cream: Whip additional heavy cream to soft peaks and gently fold it into the chocolate mixture for a light, airy mousse texture.
- Prepare White Chocolate Mousse: Repeat steps 7-11 using the white chocolate in place of dark chocolate to create the white chocolate mousse.
- Assemble the Cake – Layer One: Place one chocolate cake layer onto a serving platter as the base.
- Add Dark Chocolate Mousse: Spread an even layer of dark chocolate mousse over the first cake layer.
- Add White Chocolate Mousse: Gently spread the white chocolate mousse on top of the dark mousse layer, creating the signature tuxedo contrast.
- Top with Second Cake Layer: Place the second chocolate cake layer carefully on top of the mousse layers.
- Chill the Cake: Refrigerate the assembled cake for at least 4 hours or overnight to allow the mousse layers to set firmly.
- Prepare Chocolate Ganache: Heat the heavy cream until scalding and pour it over the chopped dark chocolate. Let the mixture sit for 5 minutes to soften the chocolate.
- Mix Ganache: Stir the ganache gently until it becomes smooth and glossy, indicating a perfect consistency for pouring.
- Apply Ganache to Cake: Let the ganache cool slightly before pouring it evenly over the chilled cake, allowing it to drip down the sides artistically.
- Decorate: Once the ganache sets, garnish the cake with chocolate shavings or fresh berries for a beautiful finishing touch.
Notes
- For a deeper chocolate flavor, use high-quality Dutch-process cocoa powder and good quality dark and white chocolates.
- Ensure all mousse ingredients are at room temperature before mixing to prevent curdling.
- Tempering the egg yolks with warm cream is essential to avoid scrambling the eggs.
- The cake must be refrigerated for several hours to set the mousse layers properly; do not skip this step.
- Espresso powder in the cake batter enhances the chocolate flavor but is optional.
- Garnish creatively with chocolate curls, berries, or edible gold flakes for a luxurious presentation.
