Actually, with coke, it's called a Colorado Bulldog. White Russian's DOES NOT have coke in them.
I have been making these for years; around here, we call them Colorado Bulldogs, and I think they favor a "pumped up' coke float. Really my favorite way to have a White Russian! I don't stir mine all the way, cause the older gentleman, who used to tend bar at an establishment I frequented, said the trick with one of these is to pull the straw up thru the drink, to get all the effects: kahlua, vodka, cream...He didn't tell me about the Coke! :-) Thanks for sharing, Karen Anne Newton RN.
