Three-Ingredient Pineapple Coconut Rum Fizz

An Easy Pineapple Coconut Rum Fizz for Summer

If you'll be hosting or attending some summer parties this year, then you'll definitely want to mix up this Pineapple Coconut Rum Fizz. It's refreshing and loaded with tropical flavors, so it's the perfect drink for outdoor gatherings, BBQ's, and picnics. The combination of coconut and pineapple is sure to make everyone smile.

One of the best things about this three-ingredient summer cocktail is how simple and quick it is to make. There are no complicated ingredients and no components that require preparation. I've even written the recipe to be made right in the serving glass, so you won't need any mixology tools. In fact, this Pineapple Coconut Rum Fizz is so easy that you can just pick up what you need at the store on the way to the beach.

Summer is a great time for outdoor gatherings, but it's frustrating to be trying to mix complicated cocktails when you have guests on the patio waiting, or if you're on a picnic. This is actually a companion recipe to my Coconut Rum Ginger Lemonade Fizz, both of which were inspired by my love of having dinner picnics on the beach. You'll be able to bring this easy coconut rum cocktail on all your adventures this summer!

Because my husband and I spend winters on the northernmost Hawaiian island, I'm a huge fan of both pineapple and coconut. In fact, I have a whole guide to tropical vegan recipes, many of which feature these two iconic island flavors.

How to Make This Pineapple Coconut Rum Fizz

This pineapple coconut cocktail is easy and fast to make, so it's perfect for a picnic. It uses only three ingredients (plus some optional garnishes), all of which you can pick up at the store on the way to the beach. Because of the minimal ingredients, this coconut rum fizz requires almost zero planning.

To make this three-ingredient summer cocktail, you'll just stir together coconut rum and pineapple juice right in the serving glass with ice, then top it with fizzy coconut water. I like to garnish it with a pineapple slice and fresh mint if I'm at home, but you can easily omit the garnishes if you're outdoors.

Tips for The Easiest Summer Beach Cocktails

If you're like me and enjoy making cocktails for picnics, spur of the moment deck parties, and evenings on the beach, then I have a few tips to help make things as easy as possible:

• Pick a very simple recipe. Especially if you're outdoors, try to choose a recipe with just a few ingredients. There's no need to over-complicate things, since outdoor mixology is already complicated enough thanks to blowing sand, buzzing bees, etc.
• Choose ready-to-go ingredients. Look for a cocktail recipe involving spirits, pre-made real juices, and easy mixers like ginger beer, tonic water, soda water, or coconut water. Avoid options with fresh citrus since trying to juice limes or lemons on the beach always makes a sticky mess. If you want to use fresh citrus, juice it at home and bring it in a small bottle.
• Mix right in the serving glass. There's no need to bring a shaker for a casual picnic cocktail. Just add the spirit and juice to the glass with ice, give it a stir, and top it with a carbonated mixer.
• Omit or simplify garnishes. No one expects a garnished cocktail at the beach. Or, if you want to go for the wow factor, pre-slice some simple garnishes and bring them in a container.
• Bring extra ice. Especially if it's sunny out, ice can melt very fast. Bring more than you think you need, ideally in an insulated container. Large thermoses or to-go coffee mugs work great for this.
• Protect your cocktail. Although open glasses are aesthetic, they can easily get spilled or filled with bugs. Try using insulated wine tumblers with lids, which will not only protect the drink but will also slow melting.

Pineapple Coconut Fizz Mocktail (or Low-ABV) Variation

Looking to make a low- or no-alcohol version of this beachy summer drink? Feel free to leave out the rum and add 1 oz fresh-squeezed lime juice for some additional complexity. For a low-ABV version, use 1 oz coconut rum instead of the 2 oz as written.

‍

Coconut Rum Pointers

For this Pineapple Coconut Rum Fizz (and every coconut rum cocktail recipe here on the blog) I use Koloa Rum Coconut Rum from Kaua'i. My husband and I spend every winter on Kaua'i and always drink it there, although Koloa Rum is available in many mainland locations and through online spirits distributors. Note that this is not the same as Malibu, which is a lower-proof coconut rum liqueur.

If you can't find Koloa and only have access to Malibu, try using 1.5 oz white rum and 1 oz Malibu (instead of the 2 oz coconut rum in the recipe card), otherwise the drink will feel too sweet.

Other Coconut Rum Cocktails to Try

If you enjoy coconut rum, you've come to the right place; I have a lot of coconut rum cocktails here on the blog. This Coconut Paloma is near-famous and is a personal go-to. Similarly, for a Mexican vibe, you'll also love this Blackberry Coconut Margarita. If you're hosting a party or having a picnic, this Coconut Rum Ginger Lemonade Fizz is easy and fast to make, and uses just a few simple ingredients. For a spring or summer brunch, try this Coconut Campari Tequila Sunrise. For an unforgettable and unique flavor combination, you'll definitely want to explore this Matcha Coconut Daiquiri.

Ingredients and Substitutions

Here's what you'll need for this Pineapple Coconut Rum Fizz, as well as some thoughts, tips, and possible substitutions. If you make any substitutions, I'd love to hear about it in the comments section below.

• Coconut rum. This easy summer cocktail is much more successful with a full-strength (80 proof) coconut infused rum; I always use Koloa Rum from Kaua'i. Using a low-proof coconut liqueur like Malibu would yield an overly sweet drink. See the section above if you only have access to Malibu.
• Pineapple juice
• Unsweetened fizzy coconut water. Look for unsweetened, unflavored, carbonated coconut water in refrigerated cans. If you can't find it, you can use non-carbonated coconut water or a 50/50 mix of coconut water and soda water.
• Optional garnishes. To make this cocktail feel especially festive, garnish it with a pineapple slice and a sprig of fresh mint.

Closing Thoughts

It's also incredibly simple to make, which is a big win for fuss-free entertaining. In fact, you can just pick up the few ingredients at the store on your way, since there's no preparation involved.

As a pro beach mixologist, let me assure you how important it is to keep things easy for yourself. After many disasters involving sticky citrus halves, blowing sand, and parades of ants, I've learned my lesson: simple is best. This Pineapple Coconut Rum Fizz is exactly what you want to reach for when you're outside.
