Let’s start at the bottom. It’s all about getting the perfect base: mix 25 crumbled cookies with melted butter. Try not to eat any! Press the mixture down into the bottom of the tin.
Dissolve the gelatine in a little warm milk and then add the remaining milk. Whip the cream until it forms firm peaks. Mix the sugar and Philadelphia together until you have a consistent mixture. Carefully mix the cream and milk mixtures together, then fold in the whipped cream. Pour the entire mixture on to the base, then leave to set in the fridge for at least 2 hours.
Now decorate with OREO cookies before serving to multiple impressed faces!
