When in Aruba, my wife L and I, along with our friends drink the famous drink of the Aruba Marriott properties - the Slippery Monkey. It is quite strong, filling and oh so yummy.
Courtesy of the Visit Aruba site, here is the recipe:
Slippery Monkey Ingredients:
1/2 oz Rum
1/2 oz Kahlua
1/2 oz Baileys Island Oasis banana frozen beverage mix (pasteurized banana mix)
Place the dark cocoa in bottom of glass (a chilled collins glass or stemmed goblet). Put all other ingredients in a blender and blend at medium-high speed for 15 seconds. Pour into a chilled collins glass or stemmed goblet and enjoy!
