Summer summer summertiiiime, but when it’s hot as a tamale out, it can be hard to sit back and unwind.

Sipping on cooling drinks can help us get through even the most sweltering days.

You can turn to the standby with gin & juice (sorry for all of the ’90s music references) or reach for something even more exciting for your taste buds.

Like this boozy watermelon papaya rum smoothie! Booze in smoothies, you ask? Oh, yes! But then again, I, Ashley tend to put booze in everything!

You won’t want to be cooking syrups or waiting days for infusions just to down a drink in no time with the heat.

So this cocktail only requires a bit of freezing (my secret tip!) and blending to get a refreshing and tasty drink that’s perfect for sipping poolside…

Using Coconut Milk In Smoothies

Instead of adding yogurt like most smoothies, I added some coconut milk.

Coconut milk not only gives the smoothie a creamy texture but also adds a tropical note that pairs so well with the papaya.

Similarly, this refreshing coconut shake recipe with only three ingredients will also become a summer favorite.

I used canned coconut milk for a thicker constancy. But you can also use refrigerated coconut milk for a lighter beverage.

How to Not Water Down Your Smoothie

Ice can often water down a smoothie, so one of my favorite tricks is freezing fruit before blending.

Freezing the coconut milk in an ice cube tray will also keep this concoction frozen longer without getting watered down, not that it will stick around for long anyways!

What Fruit Goes Well with Watermelon

There are plenty of other fruits that pair well with watermelons to make a juicy, flavorful watermelon smoothie cocktail.

Strawberries and honeydews match amazingly with watermelons — just be sure not to overdo it on the sweetness.

It’s clear from our Coconut & Strawberry Raspberry Frozen Daiquiri that strawberries go with anything!

Oranges, mangos, and pineapples all go great in watermelon smoothies while adding a slightly different flavor profile.

And if you like your watermelon mixed with something tart, kiwis are the perfect companion!

With so many fruits that pair well with watermelons, you can whip up an unbeatable watermelon smoothie cocktail for any occasion.

It’s so easy to sit back and close your eyes while drinking one of these spiked smoothies and feel like you are in a tropical local. ”Tulum” here I come!
