Kathy, here's a few ideas:
Delia Smith's
Chocolate Amaretti Cake - the recipe includes brandy but you could omit that. This may be a little hard to eat as 'finger food', though.
A couple of chocolate biscuit [cookie] cake recipes:
here and
here and
here - this one uses nuts and fruit - the advantage of these is that they are very quick and easy to make, requiring no baking; you just need to make them a couple of hours before you go so they have time to cool.
Here is a whole page full of dessert recipes! The
Danish Almond Pastry looks fairly easy as well as sounding really nice - if you can get sliced almonds and almond essence, that would work nicely.
Hope this helps!
Wendy
