Looking for recipe from Marks @ Spencer Cookbook for Truffles.?

I used to make choc. truffles that were made with ground almonds, icing sugar, choc. and some kind of cake. I moved to the States and lost the book a few years ago, my kids loved them and I would love to find the recipe. I think either brandy or rum was added too. The cookbook had to be from the 1980's. Can anybody help please.
