Ingredients

Scale

Chocolate Cake

  • 2 ¼ cups all-purpose flour (sifted)
  • 2 ½ cups granulated sugar
  • ¾ cup Dutch-processed dark cocoa powder
  • 2 ½ tsp baking powder
  • ½ tsp salt
  • 1 cup unsalted butter (room temperature)
  • 1 cup egg whites (approximately 7 large, room temperature)
  • 1 ½ cups buttermilk (room temperature)
  • 2 Tbsp vegetable oil
  • 2 tsp vanilla extract
  • 1 tsp instant espresso powder (optional)

White-Chocolate Mousse

  • ¾ cup quality white-chocolate chips
  • 1 cup heavy cream
  • 2 tbsp powdered sugar
  • 1 tsp vanilla extract

Instructions

  1. Prepare the Chocolate Cake Batter: In a large bowl, sift together the all-purpose flour, Dutch-processed cocoa powder, baking powder, and salt. In a separate mixing bowl, cream the unsalted butter and granulated sugar until light and fluffy. Gradually add the egg whites while continuing to blend.
  2. Combine Wet Ingredients: Mix together the buttermilk, vegetable oil, vanilla extract, and instant espresso powder (if using). Slowly alternate adding the dry ingredients and wet mixture to the butter and sugar mixture, starting and ending with dry ingredients, mixing until just combined.
  3. Bake the Cake Layers: Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. Pour the batter evenly into the pans. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Remove from oven and let cool completely on a wire rack.
  4. Make the White-Chocolate Mousse: Melt the white chocolate chips gently using a double boiler or microwave in short bursts, stirring frequently. Allow the melted chocolate to cool slightly. In a chilled bowl, whip the heavy cream with powdered sugar and vanilla extract until soft peaks form. Carefully fold the melted, cooled white chocolate into the whipped cream until smooth and well combined.
  5. Assemble the Cake: Once the cake layers are fully cooled, place the first layer on a serving plate. Spread a generous layer of white-chocolate mousse over it. Top with the second cake layer and cover the top and sides with the remaining mousse. Smooth the mousse with a spatula for a clean finish.
  6. Chill and Serve: Refrigerate the assembled cake for at least 2 hours to allow the mousse to set. Before serving, optionally garnish with chocolate shavings or curls for an elegant touch. Slice and enjoy your luxurious Chocolate Tuxedo Cake.

Notes

  • Ensure all ingredients are at room temperature for better mixing and texture.
  • The instant espresso powder is optional but enhances the chocolate flavor.
  • Use high-quality cocoa powder and white chocolate for the best taste.
  • Chilling the mousse before assembly helps it hold better.
  • The cake can be made a day ahead and refrigerated, making it ideal for parties.
