I used a cake form 6 1/4″ (16 cm) in diameter with removable sides. Break apart each biscuit in 2 and remove the cream from the biscuits. Crumble the biscuits in a blender and add the melted butter over them.
Blend well and distribute evenly in the cake form. Put it in the fridge while you prepare the cream mixture.
For the cream mixture - beat the liquid cream with the cream cheese, melted white chocolate and the cream from the Oreos you removed earlier into a medium thick mixture. Pour the mixture over the cake layer, decorate with 8 Oreo biscuits.
