Let’s get into what makes this cocktail stand out and how you can mix one up without breaking a sweat.
Malibu Watermelon Cooler Cocktail Recipe
I’m a fan of how Malibu Watermelon Rum’s sweetness blends with fresh juices and a bit of fizz from soda or sparkling water. The end result is refreshing and super easy to make.
It’s the kind of drink that fits any casual hangout—or just a lazy afternoon at home.
Equipment
- Cocktail shaker – I shake the rum, juices, and ice together for a quick chill.
- Muddler – I crush mint leaves or watermelon chunks to boost the flavor.
- Strainer – I pour the mix through this so I don’t get pulp or ice bits in my glass.
- Measuring jigger – I use this to keep the flavors balanced.
- Tall glass or highball glass – More room for ice, fizz, and garnish.
- Bar spoon – I give it a gentle stir after adding the bubbles.
- Ice cube tray – Gotta have plenty of ice—this drink’s best when it’s cold.
I don’t go crazy with gear, but these basics help make the drink smooth every time.
Ingredients
- 2 oz Malibu Watermelon Rum
- 1 oz vodka or gin (optional, if you want a bit more punch)
- 2 oz watermelon juice (fresh or bottled)
- 1 oz pineapple juice or orange juice
- 1 oz cranberry juice or lemonade
- 0.5 oz freshly squeezed lime juice
- Splash of sparkling water, club soda, or ginger beer
- Fresh mint leaves for muddling and garnish
- Watermelon wedge for garnish
- Ice cubes
I’ll sometimes swap pineapple juice for orange if I’m in the mood for something softer. Fresh lime juice really does taste better than bottled—just saying.
Instructions
- Fill a shaker with ice.
- Add Malibu Watermelon Rum, vodka or gin, watermelon juice, pineapple juice, cranberry juice, and lime juice.
- Shake it up for about 15 seconds until everything’s nice and cold.
- Strain into a tall glass packed with ice.
- Top off with sparkling water, ginger beer, or club soda.
- Stir gently.
- Garnish with a wedge of watermelon and some fresh mint.
That bit of fizz at the end? It totally lifts the drink and makes it extra refreshing.
Notes
I usually tweak the sweetness by playing with the juice combo. Pineapple juice makes it sweeter, cranberry adds some tartness.
If I want to keep it light, I skip the vodka or gin and just stick with Malibu. For a stronger kick, I add the vodka in.
Fresh watermelon juice is best, but if I’m in a rush, bottled works fine. Sometimes I reach for sparkling water when I want it lighter, or ginger beer if I’m craving a little spice.
A garnish of mint and watermelon not only looks great but smells super fresh too.

Tasting Notes
That first sip? It hits with a sweet watermelon flavor—light, super refreshing, and honestly, just fun. The taste stays smooth, and the fruitiness pops without ever getting too bold.
You get the Malibu coconut rum weaving in a gentle tropical vibe. I appreciate how the coconut doesn’t steal the show but instead brings a soft, creamy edge to the mix.
There’s a little citrus sneaking in, which keeps everything in check and balances out the sweetness. It really helps the cocktail stay easy to drink, never feeling heavy.
The finish? It’s clean, with a mild sweetness that hangs around just the right amount. I love how those crisp flavors linger—it’s honestly a solid pick when you’re in the mood for a simple, fruity cocktail.
Flavor highlights I notice:
- Sweet watermelon upfront
- Light coconut undertone
- Touch of citrus for balance
- Smooth, refreshing finish
