Sorry, another use for your coconut Malibu (I’m afraid I don’t have any ideas for the other two!): tropical white russians!
Take a small glass, fill with ice.
Add 1 jigger Kahlua
Add 1 jigger Malibu (the original coconut again) - takes the place of the vodka in the original
Fill with cream, half-and-half, or milk, whatever moves you
The tiki bar I frequent around here makes this, they call it the Coconaut. It’s quite tasty. Again, it’s pretty sweet.
