Pour ingredients slowly over the back of a bar spoon in order: coffee liqueur first, then crème de cacao, then Irish cream. Density differences allow them to layer without mixing.
Yes. Use equal parts (typically 0.5 oz each) of all three liqueurs, layer them in a shot glass, and drink in one go or sip slowly.
White crème de cacao is colorless and subtler; dark adds a deeper chocolate note. White is traditional for Rattlesnakes to showcase the coffee and cream layers.
