Prepare the base by crushing the biscuits and nuts and mixing butter (no need to melt) Do this in the food processor until all mixed together. Line the bottom of a springform metal cake tin with this mix and smooth out with a spoon (this recipe is for one size of the large tins - though you can adjust to the smaller ones too) Set in the fridge for about 30mins
Blend in icing sugar into cream cheese until smooth. Then mix in the toblerone. Whip Cream until fairly stiff and fold into cheese mix, add the baileys or tia marie if required. Smooth the mixture of the biscuit base (flatten the top with a knife or spoon) and set in the fridge for 2-3 hours. Lasts about 4 days once made.
One to eat and one to freeze
this freezes very well. To make two adjust quantity to 600g cheese, 370g sugar,500g tobleron, and 950ml of cream and just double the base
