You can actually make a decent homemade Kahlúa. Take a mixing bowl and add two cups of freshly brewed coffee and stir in four cups of sugar until it has dissolved. You want the coffee to be good and strong.
Leave this to one side to cool, and once it is cold, add in two cups of Rum and a vanilla bean cut in half. Put this in a cool place for two to three weeks. Strain the liquid and stir in a bottle or airtight container.
Saying that this can include a lot of faffs, so why not go with the classic and try some of the drinks below...
