Plop a few ice cubes into a glass, enough to keep it colder than the refrigerator. Next, take two parts Stolis vodka, unflavored, pour that in, add one part Starbucks coffee liqueur (the vanilla flavored coffee drink, Starbucks is my preference) then add one part whole milk.

My version of a Black Russian is the same sans the milk.

Mix in a Nalgene bottle or with measuring cups for the most accurate results, but just going by feel is what I typically do.
