Hot Buttered Rum

I saw a recipie on one of AR's blogs for Tequlia Cookies, and my wife is going to make a batch.  Here's my simple recepie for hot buttered rum:

I fill a coffee cup with water, leaving room for the rum.  I add a tablespoon of butter, put it in the microwave for 1 1/2 min.  Add a couple of tablespoons of brown sugar, a few drops of vanilla, sprinkles of nutmeg, ground cloves, and cinnamon.  Top if off with rum and merry christmas!
