Prepare a short glass full of ice then add the Bailey's Irish Cream, next add the Creme de Cacao, next add the Vanilla vodka, next add the Coconut rum, next add the Half-and-half. If you do not stir and just allow the cream to sink it will take on more of the marble appearance to go with the marble taste. However if you want a well blended drink then go ahead and roll/tumble into your glass, just don't shake it.
I've found this drink is a good alternative to my Red Marble because of the brown and creamy appearanc in the short glass and the lack of fruit juices.
