Grease a 20cm round tin with a loose bottom with a small amount of butter.
Crush the digestives in a sandwich bag and bash with a rolling pin. Make sure you don't over crush them until they go into a fine dust.
Melt your butter either on the hob on a low heat or in a microwave in 10 second bursts and mix into the crushed digestives.
Press the mixture firmly into the tin and refrigerate for atleast 30 minutes.
Meanwhile, make the filling. Soak the gelatin leaves in cold water.
Whisk the sugar, cream cheese and vanilla until light and fluffy.
In a seperate bowl, whisk the double cream until light stiff peaks form.
GENTLY heat the strawberry purée on the hob, you don't want this too hot.
Dissolve the gelatin in the purée and whisk into the cream cheese using a hand whisk or spoon.
Fold the whipped cream into the cream cheese mixture.
Take out the cheesecake base and spoon the filling mixture on top and smooth. Place any decoration of your choice on top and place back in the fridge for 6 atleast hours.
Serve chilled by itself or with a dollop of cream or ice cream on! Enjoy!
