Mix together the melted butter, digestive biscuits and cinnamon.
Spoon the mixture into a chefs ring and press down with the back of a spoon to make the base. Place into the freezer for a short period of time.
In a bowl, combine the whipped cream, mascarpone cheese, sugar and any other extras for the topping.
Spoon into the chefs ring, on top of the biscuit base. Remove the chefs ring using a hot towel or blow torch quickly. If the mixture is too runny, then refrigerate before removing the chefs ring.
Garnish and serve!
