Ingredients

1 1/2 cups (190g) all-purpose flour
1 cup (200g) granulated sugar
3/4 cup (85g) unsweetened cocoa powder
2 teaspoons baking powder
1 teaspoon salt
1/2 cup (115g) unsalted butter, at room temperature
2 large eggs, at room temperature
2 teaspoons pure vanilla extract
1 cup (240ml) whole milk, at room temperature
8 ounces (225g) high-quality dark chocolate (at least 70% cocoa), broken into small pieces
1 cup (240ml) heavy cream
Confectioners’ sugar, for dusting

Instructions

Step 1: Prepare the Cake – Preheat your oven to 350°F (180°C). Grease and flour two 8-inch round cake pans. In a medium bowl, whisk together flour, sugar, cocoa powder, baking powder, and salt. In a large mixing bowl, using an electric mixer, beat the butter until creamy. Add eggs one at a time, beating well after each addition. Gradually add the dry ingredients to the butter mixture, alternating with milk, beginning and ending with dry ingredients. Beat in vanilla extract. Divide the batter evenly between the prepared pans and smooth the tops. Bake for about 25-30 minutes or until a toothpick inserted in 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.
Step 2: Make the Mousse – In a double boiler or a heatproof bowl set over a pot of simmering water, melt the chocolate, stirring occasionally. In a separate bowl, whip the heavy cream until soft peaks form. Set aside. Once the chocolate is melted and smooth, remove it from the heat and let it cool slightly. Fold the whipped cream into the chocolate until well combined. The mousse should be smooth and light.
Step 3: Assemble the Cake – Place one of the cooled cake layers on a serving plate or cake stand. Spread a generous amount of the chocolate mousse over the top of the cake layer. Place the second cake layer on top and dust with confectioners’ sugar. You can also glaze the cake with melted chocolate for an extra layer of flavor and visual appeal.
Step 4: Final Touches – Refrigerate the cake for at least 30 minutes to allow the flavors to meld together. Just before serving, you can decorate the cake with additional whipped cream, chocolate shavings, or fresh fruit to enhance its appearance and flavor.

Handy Tips

For the best flavor, use high-quality dark chocolate with a high cocoa content. This will give your mousse a deep, rich flavor that is unmistakably chocolate.
Make sure all the ingredients are at room temperature before starting. This ensures that the cake batter and the mousse come together smoothly and evenly.
Don’t overmix the batter or the mousse. Overmixing can lead to a dense cake and a stiff mousse, which defeats the purpose of this light and airy dessert.

Heat Control

When melting the chocolate, it’s crucial to do so gently to avoid burning it. Using a double boiler is ideal as it provides a gentle heat. If you’re using a microwave, heat the chocolate in short intervals, stirring between each heating to ensure even melting and to avoid overheating.

Crunch Factor

The texture of the dark chocolate mousse cake should be a perfect balance of moist cake, light mousse, and possibly a crunch from any added toppings like nuts or chocolate shavings. To achieve the right crunch, consider adding elements like toasted almonds or hazelnuts on top of the cake before serving.

Pro Kitchen Tricks

To ensure the cake layers are even, bake them for the same amount of time and check them frequently towards the end of the baking time.
For a smoother mousse, make sure the chocolate is not too hot when folding in the whipped cream, as this can melt the cream and result in a dense mousse.
Consider using a turntable to display your cake, especially if you’re adding decorative toppings. This makes it easier to access and admire the cake from all sides.

Storage Tips

The cake can be stored in the refrigerator for up to 3 days. It’s best to store it in an airtight container to keep it fresh.
Freezing is also an option. Wrap the cake tightly in plastic wrap or aluminum foil and place it in a freezer-safe bag. Frozen cake can be stored for up to 2 months. Thaw frozen cake in the refrigerator overnight before serving.
When reheating, let the cake come to room temperature or gently warm it in the microwave. Be cautious not to overheat, as this can cause the mousse to melt.

Gift Packaging Ideas

If you’re planning to gift this cake, consider presenting it in a beautifully decorated box or on a cake stand wrapped with a clear plastic dome. You can also add a personal touch with a handwritten note or a bow around the box. For a more rustic look, wrap the cake in parchment paper and tie with twine, adding a few fresh flowers on top for a charming finish.

Flavor Variations

Different spices: Introduce a pinch of salt, a teaspoon of espresso powder, or a handful of chopped nuts to the cake batter for added depth.
Creative toppings: Top your cake with fresh fruits like raspberries or strawberries, caramel sauce, or even a sprinkle of edible gold dust for a luxurious touch.
Ingredient swaps: Replace the heavy cream with a non-dairy alternative for a vegan version, or use different types of chocolate for varying flavor profiles.

Troubleshooting

Texture problems: If the mousse turns out too dense, it might be due to overmixing or using chocolate that’s too hot. If the cake is too dry, it could be overbaked.
Ingredient replacements: Always try to use the ingredients mentioned in the recipe for the best results. However, if you need to make substitutions, ensure they are as close to the originals as possible in terms of flavor and texture.
Over/undercooking signs: A toothpick inserted into the cake should come out clean or with a few moist crumbs. If it’s covered in wet batter, the cake needs more time. For the mousse, if it’s too runny, it might not have been chilled enough.

FAQs

Can I freeze it? Yes, you can freeze the cake for up to 2 months. It’s best to freeze it in an airtight container or freezer bag.
Is it gluten-free? The cake contains wheat flour, making it not gluten-free. However, you can experiment with gluten-free flours as a substitute, though this might affect the texture and flavor slightly.
Can I double the recipe? Yes, you can double the recipe to make a larger cake. Just ensure you have enough pans and space in your refrigerator for the assembled cake.
