Soak the gelatine leaves in cold water.
Using an electric mixer, whisk together the cream cheeses, vanilla, sugar and coconut milk (only the white part) until smooth. Reserve the coconut water.
Pour into the mix the double cream and continue to whisk for a couple of minutes until it’s very thick and mousse-like.
Heat the coconut water in a saucepan. Squeeze excess water from gelatine leaves and add it to the coconut water. Remove from the heat and stir until the gelatine dissolves.
Whisk the gelatin mixture into the cream mixture.
Pour the filling into the crust and refrigerate until firm (more or less 6h)
