Not too many traditional favorites from my childhood, except for when grandma would make fruitcake. She didn't make it a rum cake, but she would soak it in bourbon (dad always had a jug of Jim Beam in the house). The cake would be on the kitchen counter under a towel, and once or twice a day for a few days grandma would lift up the towel and splash liberal amounts of the booze on it.
Sadly, I had not developed a taste for the brown liquors at that point, so it wasn't very appealing to me. I'm sure it was quite tasty...
In recent years, my own traditions include a very simple 5-minute fudge recipe (sometimes with walnuts or pecans), and chocolate covered peanut butter balls. Both are always a big hit!
