Preheat oven to 350°F (175°C). Grease and line a 9-inch round cake pan.
In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
Add eggs, oil, buttermilk, and vanilla. Mix until smooth.
Pour into prepared pan and bake for 25–30 minutes. Let cool completely.
2. Prepare the Mousse
Melt dark chocolate and milk chocolate separately using a double boiler. Allow them to cool slightly.
In a small bowl, dissolve gelatin in water and let bloom for 5 minutes. Heat gently until dissolved.
Whip 400 ml heavy cream with powdered sugar until soft peaks form.
Divide whipped cream in half. Fold one half into melted dark chocolate + gelatin, and the other half into melted milk chocolate. Chill for 15 minutes.
