Instructions

📝 Instructions:

Step 1: Bake Cake Layers

Preheat oven to 350°F (175°C). Grease and flour two 9-inch round pans.
Whisk flour, cocoa, baking powder, and salt in a bowl.
In a large bowl, cream butter and sugar until fluffy. Beat in eggs, one at a time, then add vanilla.
Alternate adding dry ingredients and milk until smooth.
Divide batter evenly between pans and bake 30–35 minutes. Cool completely.

Step 2: Prepare White Chocolate Mousse

Melt white chocolate in a heatproof bowl over simmering water. Let cool slightly.
Whip heavy cream with powdered sugar until soft peaks form.
Fold melted white chocolate into whipped cream gently. Chill until ready to assemble.

Step 3: Make Chocolate Ganache Frosting

Heat cream until just simmering, pour over chopped chocolate.
Let sit 2 minutes, then stir until smooth. Cool to spreadable consistency.

Step 4: Assemble the Cake

Place one chocolate cake layer on a serving plate.
Spread white chocolate mousse evenly on top.
Add second cake layer and cover with chocolate ganache frosting.
Smooth frosting and optionally create a layered or marbled “tuxedo” effect with white chocolate drizzle.

Step 5: Decorate

Sprinkle chocolate shavings or curls on top.
Dust edges lightly with cocoa powder or add a white chocolate drizzle for elegance.

Notes

Make Ahead: Cake layers can be baked a day prior; mousse and ganache can also be prepared in advance.
Mousse Tip: Chill mousse slightly before spreading to prevent it from melting the cake layers.
Mini Version: Make cupcakes with alternating chocolate and white chocolate mousse layers.
