Steps / Instructions

Prepare the Cake: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan thoroughly to prevent sticking.
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until combined, ensuring there are no clumps.
Add the eggs, vegetable oil, buttermilk, and vanilla extract to the dry ingredients. Mix until well combined, ensuring no lumps remain for a smooth batter.
Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let it cool completely in the pan before transferring to a wire rack.
Make the Chocolate Mousse: Melt the chopped dark chocolate in a heatproof bowl over simmering water or in the microwave in 20-second intervals. Allow it to cool slightly but not harden.
In another bowl, whip the heavy cream with sugar and vanilla extract until soft peaks form, which indicates it’s ready for folding. Gently fold in the melted chocolate until fully combined without deflating the whipped cream.
Once the cake has cooled, slice it horizontally to create two even layers. Place one layer back in the cake pan, ensuring it’s centered.
Spoon half of the chocolate mousse onto the first layer and spread it evenly, reaching the edges for a neat finish. Place the second layer of cake on top, aligning it well.
Top the second layer with the remaining mousse and smooth the top with a spatula. Cover with plastic wrap and refrigerate for at least 4 hours or overnight for the best texture.
Prepare the Ganache: Heat the heavy cream in a saucepan until just steaming but not boiling. Pour it over the chopped chocolate in a bowl and let it sit for 5 minutes to melt, ensuring a creamy consistency.
Stir the mixture until it’s smooth and glossy, indicating the ganache is ready. Let it cool slightly before pouring it over the chilled mousse cake for a beautiful finish.
Carefully remove the cake from the pan and place it on a serving plate. Pour the ganache over the top, allowing it to drip down the sides for an elegant effect.
Decorate with whole Ferrero Rocher chocolates and chopped hazelnuts for an elegant finish, making it visually stunning and inviting.

Tips & Tricks

To achieve the best results, ensure your ingredients are at room temperature before mixing. This helps create a smoother batter and better mousse consistency, leading to a more luxurious cake. If you want to make the cake ahead of time, it can be stored in the refrigerator for up to 2 days before serving, allowing flavors to meld beautifully. For a richer flavor, consider using high-quality dark chocolate for both the mousse and ganache, as it greatly enhances the overall taste. When folding in the whipped cream for the mousse, be gentle to maintain the light and airy texture, which is crucial for a successful mousse. If you have leftovers, keep them covered in the refrigerator for up to 3 days for maximum freshness.
