Key Lime Island Vibes

Decided to make a cool cocktail variation based-off a key lime martini. Turned out pretty good.

Recipe

2 oz rum (preferably dark)

Teaspoon of brown sugar (table sugar still works)

1/4 oz fresh lime juice 

2 drops of vanilla extract

1 oz milk (coconut cream optional)

Shake vigorously with ice in a shaker

Pour in a glass

Lime wheel for garnish

Top cocktail w/ cinnamon and nutmeg
