• 1/4 teaspoon salt
• 1/2 cup unsalted butter, softened
• 1 cup granulated sugar
• 2 large eggs

• 1/2 cup whole milk
• 1/2 cup boiling water

For the Dark Chocolate Mousse:

• 6 oz dark chocolate (70% cocoa)
• 1 cup heavy cream
• 1 tablespoon sugar
• 1 teaspoon vanilla extract

For the Milk Chocolate Mousse:

• 6 oz milk chocolate
• 1 cup heavy cream
• 1 tablespoon sugar
• 1 teaspoon vanilla extract

For the White Chocolate Mousse:

• 6 oz white chocolate
• 1 cup heavy cream
• 1 tablespoon sugar
• 1 teaspoon vanilla extract

For the Chocolate Ganache:

• 4 oz dark chocolate
• 1/2 cup heavy cream

Equipment:

• 9-inch springform pan
• Hand mixer or stand mixer
• Mixing bowls
• Whisk
• Spatula

Instructions:

Step 1: Bake the Chocolate Cake Base

1. Prepare the cake batter: Preheat your oven to 350°F (175°C). Grease and line a 9-inch springform pan with parchment paper. In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
2. Mix wet ingredients: In another bowl, cream together the butter and sugar using a hand mixer or stand mixer until light and fluffy. Add eggs, one at a time, beating well after each addition. Stir in vanilla extract.
3. Combine the wet and dry ingredients: Alternate adding the dry ingredients and milk to the butter mixture, beginning and ending with the dry ingredients. Mix until smooth.
4. Add boiling water: Carefully pour in the boiling water and stir until the batter becomes thin and smooth.
5. Bake the cake: Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the pan before removing.

Step 2: Make the Dark Chocolate Mousse

1. Melt the chocolate: Chop the dark chocolate into small pieces and melt it using a double boiler or in the microwave in 30-second intervals, stirring in between.
2. Whip the cream: In a mixing bowl, whip the heavy cream and sugar until soft peaks form.
3. Combine the chocolate and whipped cream: Once the chocolate has melted and slightly cooled, gently fold in the whipped cream. Add vanilla extract and mix until well combined. Set aside.

Step 3: Make the Milk Chocolate Mousse

1. Melt the milk chocolate: Chop and melt the milk chocolate the same way as the dark chocolate.
2. Whip the cream: In a separate bowl, whip the heavy cream and sugar to soft peaks.
3. Combine the milk chocolate and whipped cream: Fold the whipped cream into the melted milk chocolate, then add vanilla extract. Set aside.

Step 4: Make the White Chocolate Mousse

1. Melt the white chocolate: Chop the white chocolate and melt it using the same method as the dark and milk chocolate.
2. Whip the cream: In another bowl, whip the cream and sugar until soft peaks form.
3. Combine the white chocolate and whipped cream: Gently fold the whipped cream into the melted white chocolate, followed by the vanilla extract. Set aside.

Step 5: Assemble the Cake

1. Prepare the springform pan: If necessary, cut the cooled chocolate cake into two even layers. You can also skip this step and use the entire cake as a base, depending on the thickness of the cake layer you prefer.
2. Layer the mousse: Start by spreading the dark chocolate mousse evenly over the cake base in the springform pan. Smooth the top with a spatula and refrigerate for 30 minutes to set.
3. Add the milk chocolate mousse: After the dark chocolate mousse has set, add the milk chocolate mousse in the same manner. Refrigerate for another 30 minutes to firm up.
4. Top with white chocolate mousse: Finally, spread the white chocolate mousse on top and smooth it out. Refrigerate for 2-3 hours, or preferably overnight, to allow all the layers to set properly.

Step 6: Prepare the Chocolate Ganache

1. Melt the ganache: Chop the dark chocolate into small pieces and melt it with the heavy cream, either using a double boiler or in the microwave in short bursts.
2. Pour the ganache: Let the ganache cool for a few minutes, then pour it over the top of the cake. Use a spatula to gently smooth it over the top and let it drip down the sides for a beautiful effect.

Step 7: Final Touches and Serving

1. Decorate the cake: Once the ganache has set, you can decorate the cake with chocolate shavings, berries, or whipped cream for added flair.
2. Serve: Carefully release the cake from the springform pan and transfer it to a serving plate. Slice with a sharp knife, ensuring that each slice has a layer of each mousse.

This triple chocolate mousse cake is a rich, indulgent dessert that’s perfect for special occasions or when you want to impress your guests with something truly spectacular.
