I love the old fashioned Cream Drops. Every Christmas I have to buy several of them. Sometimes, they are hard to find here. I also like the Brach's candy nougat things that are soft peppermint with the tree in the middle.
There are a lot of extra treats that we do buy at Christmas; but probably just as many that we make ourselves. Every year I make 3 kinds of fudge and probably half a dozen different varieties of Christmas cookies. The fudge is definitely my favorite.
