Cake Preparation
- Preheat your oven to 350°F (175°C) and grease three 9-inch round cake pans, lining the bottoms with parchment paper.
- In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, and salt.
- In a separate bowl, combine butter, egg whites, buttermilk, oil, vanilla, and espresso powder.
- Mix wet ingredients into dry mixture until just combined, then divide the batter among the pans.
- Bake for 30-35 minutes, or until a toothpick comes out clean.
Cooling and Mousse Preparation
- Allow the cake layers to cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
- To make white chocolate mousse, melt the white chocolate with warm water and cool to room temperature.
- Whip heavy cream with powdered sugar until soft peaks form, then fold in cooled white chocolate.
- Refrigerate the mousse for at least 2 hours.
- Repeat the process for dark chocolate mousse, using dark chocolate chips.
Ganache Preparation and Assembly
- Heat heavy cream for ganache until simmering, pour over dark chocolate chips, and mix in corn syrup.
- Allow ganache to cool to a pourable consistency.
- Level the tops of the cake layers, then layer with white and dark mousse.
- Cover with the last cake layer, refrigerate for 30 minutes.
- Pour ganache over the top and refrigerate for at least 2 hours before serving.

Notes
Ensure all ingredients are at room temperature for best results. Chill bowls before whipping cream for stability.
