Place the Biscuits in a plastic bag and smash together with a rolling pin until it looks like sand (you could also use a food processor) Then add the melted Butter and Salt coating all of the biscuits.
Put a sheet of baking paper over the bottom of the tin - put your tin on top and scrunch the remaining paper under the tin.
Press the Biscuit mixture evenly and firmly into the base and halfway up the sides of the cake tin, finish pressing it with your fingers to make it even – refrigerate.
Whip Cream in a mixing bowl using a stand mixer ensuring it remains cold by placing it in the fridge whilst you do the next steps.
In the same bowl, using the same stand mixer - whip the Cream Cheese room temperature, Vanilla and Sugar until completely smooth.
Break apart the White Chocolate and put in a bowl, heat in the microwave for 1:30 mins, stirring until almost melted – do not overheat, stir until completely melted.
Using a spatula, gently stir the Cream and White Chocolate into the Cream Cheese mixture until completely incorporated.
Stir in the Funfetti Sprinkles with a spatula and spread the filling evenly over the Biscuit base, sprinkle with more Funfetti Sprinkles! Refrigerate until set.
