The fresh lime flavor keeps it bright while the cream gives it that rich pie filling texture. It’s sweet without becoming heavy, which makes it surprisingly easy to enjoy even after a big meal.

Ingredients
This cocktail works because each ingredient helps recreate the flavor of classic key lime pie. The citrus, cream, vanilla, and graham cracker notes all come together into a dessert-style martini that still feels refreshing.
You’ll need:

Coconut rum gives the cocktail a tropical sweetness that pairs naturally with lime and cream. It also helps create that beachy dessert flavor people instantly recognize.
Suggested Liquor Brands and Substitutions

Rich vanilla flavor without tasting overly artificial. - Absolut Vanilla Vodka

Helpful tools include:
- Cocktail Shaker
