• 1 3/4 cups (220g) all-purpose flour
• 1 1/2 teaspoons baking powder
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1/2 cup (115g) unsalted butter, softened
• 1 cup (200g) granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/2 cup (120ml) whole milk
• 1/2 cup (120ml) hot water
• 1/2 cup (45g) unsweetened cocoa powder

For the White Chocolate Mousse:

• 6 oz (170g) white chocolate, chopped
• 1 1/4 cups (300ml) heavy cream
• 1 teaspoon vanilla extract

For the Dark Chocolate Mousse:

• 6 oz (170g) semi-sweet or bittersweet chocolate, chopped
• 1 1/4 cups (300ml) heavy cream
• 1 teaspoon vanilla extract

For the Ganache Glaze:

• 1/2 cup (120ml) heavy cream
• 4 oz (115g) semi-sweet chocolate, chopped
• 1 tablespoon unsalted butter

For Decoration (optional):

• White chocolate curls or shavings
• Dark chocolate curls or shavings

Instructions:

Prepare the Chocolate Cake Layers:

1. Preheat your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper.
2. In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cocoa powder. Set aside.
3. In a large bowl, cream together the softened butter and sugar until light and fluffy (about 3-5 minutes).
4. Beat in the eggs one at a time, then add the vanilla extract.
5. Gradually add the dry ingredients to the butter mixture, alternating with the milk. Begin and end with the dry ingredients. Mix until just combined.
6. Pour the hot water into the batter, mixing until smooth. The batter will be thin.
7. Divide the batter evenly between the two prepared cake pans.
8. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Prepare the White Chocolate Mousse:

9. Melt the white chocolate in a heatproof bowl over a double boiler or in the microwave in 30-second intervals, stirring after each interval. Let the melted white chocolate cool slightly.
10. In a separate bowl, beat the heavy cream until stiff peaks form.
11. Fold the cooled white chocolate into the whipped cream until fully combined. Set aside in the refrigerator.

Prepare the Dark Chocolate Mousse:

12. Melt the dark chocolate in the same way as the white chocolate, either over a double boiler or in the microwave. Let it cool slightly.
13. In a separate bowl, beat the heavy cream until stiff peaks form.
14. Fold the cooled dark chocolate into the whipped cream until fully combined. Set aside in the refrigerator.

Prepare the Ganache Glaze:

15. Heat the heavy cream in a small saucepan until it begins to simmer. Remove from heat.
16. Add the chopped semi-sweet chocolate and butter, stirring until smooth and glossy. Let it cool slightly before using.

Assemble the Cake:

17. Once the cakes have cooled, slice each cake layer in half horizontally to create four layers.
18. Place the first cake layer on a serving platter. Spread a layer of dark chocolate mousse over it.
19. Place the second cake layer on top of the mousse, followed by a layer of white chocolate mousse.
20. Continue layering the cake with dark and white mousse until all layers are stacked, alternating the mousse between each layer.
21. Finish with a layer of the final cake layer on top.

Glaze and Decorate:

22. Pour the ganache glaze over the top of the assembled cake, allowing it to drip down the sides.
23. Garnish with white and dark chocolate curls or shavings to decorate the cake.

Serve:

24. Let the cake set for about 30 minutes before serving to allow the ganache to firm up. Slice and enjoy!

Tips for Success:

• Make sure the cake layers are completely cool before assembling the cake to prevent the mousse from melting.
• To create even layers of mousse, use an offset spatula to spread them evenly across the cake layers.
• For the ganache glaze, ensure the cream is hot enough to melt the chocolate completely but not boiling.

Recommendations:

• Serve the cake with a cup of coffee, espresso, or dessert wine like Moscato for a delightful pairing.
• Leftover cake can be stored in an airtight container in the refrigerator for up to 3 days. Allow it to come to room temperature before serving for the best texture.
