Dirty Banana Cocktail: Choccy & Banana Infusion

dirty banana cocktail recipe

The exact genesis of this frosty tipple remains a mystery, yet its blend of matured rum, banana, coffee liqueur, and half-and-half establishes it as a favorite for summer days and nights alike.

This particular recipe benefits from the use of a slightly overripe banana, whose intensified sweetness perfectly complements the tropical, spirited essence of the drink.

Opting for an aged rum adds a robust foundation and introduces deep, caramel-like nuances, elevating this tropical boozy smoothie to new heights of flavor complexity.

Its name, suggestive of its main ingredients, invites you into a world of flavor that’s as fun to prepare as it is to sip.

Here’s an in-depth guide to making the Dirty Banana, perfect for any occasion that calls for a little tropical escapism.


Dirty Banana Ingredients

  • Rum (2 ounces / 60 ml): Acts as the backbone of the cocktail, providing a subtle sweetness and warmth that lifts the tropical notes of the banana and the depth of the coffee liqueur.
  • Banana Liqueur (1 ounce / 30 ml): Brings a banana flavor that intensifies the tropical essence of the cocktail.
  • Coffee Liqueur (1 ounce / 30 ml): Adds complexity with its rich, bitter notes, creating a contrast to the sweetness of the banana and rum.
  • Half-and-Half (2 ounces / 60 ml): For a lighter creaminess, half-and-half smooths out the drink, marrying the flavors into a whole. Alternatively, a mix of heavy cream and whole milk can be used to adjust the creaminess to your liking.
  • Banana (1, slightly overripe): The star ingredient, a ripe banana, lends natural sweetness and body, making the cocktail smooth.
  • Garnish: A chunk of banana, with peel, adds a decorative touch that hints at the cocktail’s main flavor profile.

Dirty Banana Recipe

  1. Preparation:
    • Begin by gathering your ingredients, ensuring the banana is ripe for the perfect sweetness and texture. A slightly overripe banana is ideal for its enhanced flavor and smoothness in the blend.
  2. Blending the Cocktail:
    • In a blender, combine 60 ml (2 ounces) of rum, 30 ml (1 ounce) of banana liqueur, 30 ml (1 ounce) of coffee liqueur, 60 ml (2 ounces) of half-and-half, and the chunks of one ripe banana.
    • Add a small scoop of ice, about 6 ounces, to the blender. The ice not only chills the drink but also contributes to its silky texture.
    • Blend the mixture until smooth, ensuring there are no chunks of ice or banana left, to achieve a creamy consistency that’s both rich and utterly smooth.
  3. Serving:
    • Choose a Collins glass for its tall, slender shape, which showcases the creamy texture and light color of the cocktail beautifully. Pour the blended mixture into the glass, filling it to just below the rim.
  4. Garnishing:
    • Garnish with a chunk of banana (with peel) on the rim of the glass. This not only adds to the visual appeal but also reinforces the cocktail’s primary flavor.

The Dirty Banana Cocktail – In Depth

Among the favorites like Piña Coladas and the Bahama Mama, if you have a penchant for bananas, a drink of aged rum, banana, coffee liqueur, and half-and-half might soon top your list of beloved frozen beverages.

The birthplace of the Dirty Banana is a bit of a mystery, but it has become a staple at numerous Caribbean resorts today. And if you’re not on holiday, worry not—this tropical drink is just as yummy whipped up in your kitchen as it is enjoyed at a swim-up bar.

The essence of this drink lies in choosing aged rum, which infuses a caramel-like depth and complements the banana’s natural sweetness. Consider trying spiced rum to introduce an additional layer of complexity against the creamy backdrop. While light rum might work in a bind, it’s better reserved for lighter, crisper cocktails like Daiquiris and Mojitos, as it lacks the richness aged rum contributes.

The Essence Lies In the Ingredients

The cocktail’s fruity essence is derived from both fresh banana and banana liqueur.

Overripe bananas on your counter are perfect for this recipe, offering up their intensified sweetness. When it comes to the banana liqueur, options like Giffard Banane du Brésil or Tempus Fugit Crème de Banane are favored for their genuine banana taste.

You’ll need just one ounce (30 ml), so it’s okay to opt for a more budget-friendly or accessible choice, such as Bols or 99 Bananas. Coffee liqueur, such as Kahlúa, adds a deep, rich flavor and an extra layer of alcohol, setting the Dirty Banana apart from a mere Banana Daiquiri.

By blending half-and-half and ice, you transform this cocktail into a boozy milkshake. Some variations even include chocolate syrup, further playing up the “drinkable dessert” angle. However you choose to blend it, the result is bound to make you go wild with enjoyment.
