This will be too late but... mix crumbed biscuits with butter and push into the bottom of ramekins or a flan dish), heat the cream, stir in broken up chocolate until melted, add a dash of milk and beat til glossy and pour onto biscuit base. Leave to set. Lick saucepan clean.
It's basically a simplified version of Jamie Oliver's "simple chocolate Tart" (I can find the proper recipe/quanitites if you like). I used to make it with a proper pastry case, then got lazy and made it with a biscuit crumb base and now I forget the base and pour it into little pots instead. Next I'll be eating it straight from the saucepan. It works well with marscapone cheese too.
