While I’ll never (never ever ever) turn down creamy frozen treats during the hot summer months, like homemade chocolate chip cherry ice cream and semifreddo, I love the option to make a refreshing beverage with a bit of booze.

Especially with a recipe as simple as this one.

With just watermelon, rum, lime juice, and agave syrup, this four-ingredient drink doesn’t hide behind any artificial sweeteners, and doesn’t require a long list of complicated craft cocktail ingredients.

And rather than adding ice cubes, you freeze watermelon chunks to make this a delightfully frozen drink with the freshest, juiciest flavors.

With a quick push of a button on your blender, all of the ingredients blend together to make one of the best slushies you’ve ever had.

It’s exactly what you need as you lazily lounge under the warm sun, without a care in the world. With this daiquiri in your hand, you can enjoy your own sweet paradise.

Just ignore your very loud kids screaming and fighting in the pool. You can always add just a little more rum to your cup, if necessary…

Cooking by the Numbers…

Step 1 – Freeze the Fruit

Preparing the watermelon yourself? With a large, sharp knife and sturdy cutting board, cut it into large cubes. Evenly spread the cubes on a sheet pan covered with waxed paper or a silicone mat.

For a quick demo on cutting melon like a pro, check out our cantaloupe tutorial here. It’s a similar process, without any seeds to scoop! (And on that note, make sure you buy a seedless watermelon, or you’ll be doing a lot of picking before you toss the fruit into your blender).

Freeze for at least 8 hours, or overnight. Remove from the freezer when you are ready for the next step.

Step 2 – Gather and Measure Ingredients

Remove the frozen fruit cubes from the freezer. Measure out the light rum and agave syrup. Juice the limes.

If using, prep your garnishes.

Step 3 – Blend

Place all of the ingredients in a large blender. Blend on high for 30 seconds, until all of the cubes have been evenly blended. You could also use your food processor for this, if it is large enough.

Too thick? Add a small amount of cold water (or more rum!) to thin out the mixture.

Step 4 – Serve

Pour the mixture into four small glasses, divided evenly between them. Garnish, serve, and drink! You can even pour the mixture into ice pop sleeves for an on-the go party!

Fruity Frozen Fun

When you’re not in the mood for ice cream sandwiches or smoothies, and are craving something light and fruity, blend up a big batch of these frozen watermelon daiquiris.

With no dairy and no artificial sweeteners, you can enjoy a boozy concoction of pure and simple summery ingredients that will delight and refresh.

It’s the perfect slushie, made just for adults!

If you’re avoiding alcohol, simply replace the rum with your choice of fruit juice – orange or pomegranate are tasty options. You can also use a more effervescent drink, like tonic or ginger ale.

Love this boozy beverage? Try out another rum-happy delight, with our rum punch popsicles. But we think you’ll appreciate using up any remaining watermelon to make a different summery delight: our sparkling watermelon cocktails!
