Sprinkle gelatin over cold water; let sit 5 minutes.
Melt dark chocolate until smooth (microwave or double boiler).
Heat 2 tbsp of the cream and dissolve gelatin into it.
Stir gelatin mixture and vanilla into the melted chocolate.
Whip remaining cream until soft peaks form, then gently fold into chocolate.
Spread over cooled cake base and refrigerate for 30–45 minutes.
