From Chicago's Three Dots and a Dash
.5oz Cruzan Blackstrap Rum
.5oz Blended Lightly Aged Rum
1oz Pineapple Juice
.75oz Lime Juice
.75oz Demerara Syrup
.25oz Cold Brew Coffee or Kahlua
Shake all ingredients with ice and strain into a glass or Tiki mug with crushed ice. Garnish with pineapple fronds and coffee beans.
I didn't have a pineapple on hand so I garnished with some mint. It looks pretty, but the mint does NOT jive with the rest of the cocktail. However, the beans are a must; the coffee aroma adds a lot to the flavor of the drink.
