How about some stollen? I've made mini stollen (two-bite sized) before, and they went down really well. I love homemade truffles as well - if you make up a batch of a truffle mix, you can split it into different batches and add all sorts of flavours. Baileys is one of my favourites (has anyone tried the new biscotti flavour?), but rum, whisky, tia maria, cointreau and other alcohols are good. So are spices like cardamon, cinnamon, ginger and chili.
Another idea - spiced nuts. Coat some mixed nuts in melted butter (a couple of tablespoons is usually enough), then roast until toasted (20-30 mins, stirring occasionally). Sprinkle over a mix of spices/herbs of your choice and stir to coat. Garlic salt is nice, so is cayenne pepper, smoked paprika... you can be as imaginative as you like really. You can also add soy sauce, Worcester sauce, Henderson's relish, etc. at the same stage as mixing the butter with the nuts for extra flavour. Once the nuts have cooled, put them in a nice jar and you've got a lovely savoury snack.
