Mum and I do:

- shortbread wreaths piped in circles and decorated with glace cherries
- almond toffee crisps
- starry night tarts
- stained glass biscuits (cut out a shape in the middle and fill with crushed lollipops before baking - these can be hung on the tree)
- chocolate truffles
- cherry ripe
- apricot balls

I am sure there are more, but that's a start!

ETA - mince pies, too!
