Embrace the Summer Vibe with Watermelon Malibu Slush

Living abroad, I’ve come to appreciate efficiency, especially with smaller kitchen appliances. A compact oven, a modest fridge, and a petite freezer mean every inch of space counts. Yet, despite these limitations, there’s one essential item I always insist on having stashed away: frozen cocktail slushies. The secret? Alcohol prevents them from freezing solid, transforming them into a delightful, scoopable treat that’s always ready when you are. And today’s star slush? A captivating Watermelon Malibu blend!

This recipe is born from the common joy (and occasional predicament) of buying a watermelon that’s simply too big to conquer in one go. Instead of letting delicious fruit go to waste, chop it up and freeze the pieces on a tray. This simple step ensures you always have a stash of frozen watermelon cubes on hand, perfect for smoothies, fruit salads, or, as in today’s case, creating this spectacular Watermelon Malibu Slush. It’s a fantastic way to extend the life of your favorite summer fruit and minimize food waste.

The beauty of this slush lies in its simplicity. You’ll just combine frozen watermelon, smooth Malibu coconut rum, fresh lime juice, and a touch of sugar in a blender. Blend until you achieve a silky-smooth consistency, and voilà – your tropical paradise is ready! Any leftovers can be easily stored in a freezer-safe container or resealable bag, ensuring you have tasty, boozy slushies at your fingertips anytime the craving strikes. This make-ahead aspect makes it an absolute lifesaver for summer entertaining, allowing you to enjoy your guests without fussing over drinks.

Essential Ingredients for Your Watermelon Malibu Slush

  • 2 to 4 Tbsp sugar: Adjust this to your preference, depending on the sweetness of your watermelon and how sweet you like your cocktails.
  • 2 Tbsp lime juice: Freshly squeezed lime juice adds a bright, zesty counterpoint to the sweetness of the watermelon and coconut, balancing the flavors beautifully.

Frequently Asked Questions About Watermelon Malibu Slush

To help you perfect your Watermelon Malibu Slush and answer any common queries, here are some frequently asked questions:

Can I make this slush non-alcoholic?

Absolutely! For a family-friendly version, simply omit the Malibu rum and add a splash of coconut water or sparkling water for a similar tropical vibe. You can also increase the lime juice or add a different fruit juice to compensate for the missing liquid. It will still be incredibly refreshing and delicious for all ages.

How do I make sure my watermelon is sweet enough?

When choosing a watermelon, look for one that is heavy for its size. A dull, not shiny, rind with a large, creamy yellow spot (the “field spot” where it rested on the ground) indicates ripeness. You can also give it a good thwack; a deep, hollow sound usually means it’s ripe and juicy.

What if I don’t have frozen watermelon?

If you’re short on time and don’t have pre-frozen watermelon, you can use fresh watermelon and add about 1-2 cups of ice cubes to the blender. However, using all frozen watermelon will yield a richer, more concentrated flavor and a thicker, smoother slushy texture without diluting the taste. It’s highly recommended to freeze the watermelon for the best results.

Can I use a different type of rum?

While Malibu rum (coconut-flavored) is recommended for its distinct tropical taste, you can certainly experiment! A light rum would work well if you prefer a less pronounced coconut flavor. Dark rum might be too strong and alter the light, refreshing profile. White rum could also be a good alternative if you want to keep it simple.

How long does the slush last in the freezer?

When stored in an airtight, freezer-safe container or bag, your Watermelon Malibu Slush can last for up to 2-3 weeks in the freezer. The alcohol content prevents it from freezing solid, so it remains scoopable. Just give it a good stir before serving if it’s been sitting for a while.

Can I adjust the sweetness?

Yes, the amount of sugar is entirely adjustable. Start with 2 tablespoons, blend, and taste. If your watermelon is very ripe and sweet, you might need less sugar. If it’s less sweet or you prefer a sweeter drink, add another tablespoon or two. You can also use a liquid sweetener like agave nectar or simple syrup for easier blending.

What are some good garnishes for this slush?

Elevate your Watermelon Malibu Slush with fun garnishes! A small wedge of fresh watermelon, a lime wheel, a sprig of fresh mint, or even a tiny umbrella can add a festive touch. For an extra special presentation, rim your glass with sugar or a mixture of sugar and lime zest.

Ingredients

  • 4 cups frozen watermelon chopped into cubes
  • ½ cup Malibu rum (coconut-flavored)
  • 3 Tbsp sugar (adjust to taste)
  • 2 Tbsp lime juice (freshly squeezed is best)

Before You Begin

For best results, ensure your watermelon is thoroughly frozen. Store any leftover slush in the freezer in an airtight container for easy future enjoyment.

Instructions

  • Combine all listed ingredients (frozen watermelon, Malibu rum, sugar, and lime juice) into a high-speed blender. Secure the lid and blitz until the mixture is completely smooth and resembles a uniform slush. You may need to pause and scrape down the sides of the blender with a spatula to ensure all ingredients are evenly incorporated and there are no frozen chunks remaining.
  • Pour the freshly blended Watermelon Malibu Slush into serving glasses. Garnish with a fresh lime wedge or a small slice of watermelon, if desired. Serve immediately for the best icy-cold experience!
  • Any remaining slush can be transferred to an airtight, freezer-safe container and stored in the freezer for later. Due to the alcohol content, it won’t freeze solid, allowing for easy scooping whenever you desire another refreshing drink.

The recipes on this blog are tested with a conventional gas oven and gas stovetop. It’s important to note that some ovens, especially as they age, can cook and bake inconsistently. Using an inexpensive oven thermometer can assure you that your oven is truly heating to the proper temperature. If you use a toaster oven or countertop oven, please keep in mind that they may not distribute heat the same as a conventional full sized oven and you may need to adjust your cooking/baking times. In the case of recipes made with a pressure cooker, air fryer, slow cooker, or other appliance, a link to the appliances we use is listed within each respective recipe. For baking recipes where measurements are given by weight, please note that results may not be the same if cups are used instead, and we can’t guarantee success with that method.
