Pineapple rum slush is a smooth and sweet alcoholic beverage that's made with just three ingredients in a blender. This tropical drink is made with frozen pineapple, rum, and coconut water.

This pineapple rum slush is a smooth frozen alcoholic drink that's made in the blender. With just three ingredients you'll have a fruity and fun summer drink to enjoy by yourself or with friends.
Frozen pineapple is the key ingredient in this recipe. If you don't have frozen pineapple, you can freeze your own in chunks beforehand. Coconut water gives this drink a tropical feel, but can be swapped with pineapple juice for a stronger pineapple flavor.
Add a splash of rum to top off this fun summer drink - or omit for an alcohol-free version.
Ingredients
For this recipe, you'll need coconut water, frozen pineapple chunks, and rum.
For the rum, simply use your favorite - dark rum, coconut rum, clear rum - or you can substitute with vodka or tequila.
Coconut water can be substituted with pineapple juice or orange juice.
How to freeze pineapple
For this recipe, I bought a 16 ounce bag of Dole Pineapple Chunks in the freezer aisle, which makes exactly two drinks. If you can't find frozen pineapple, you can prep your own the day before.
Slice your pineapple into chunks and spread onto a parchment/wax paper lined cookie sheet. Freeze for a few hours or overnight, then store them in a freezer bag until ready to use.
Blending your drink
Simply add your ingredients, liquid first, into a blender. Seal with a lid and blend until the consistency is smooth and creamy, with no lumps.
If your drink is too thick, add more coconut water as needed.
Coconut water substitutes
If you don't like or have coconut water, you can easily substitute it with coconut milk, pineapple juice, or orange juice. You'll need the liquid in your drink to thin out the frozen pineapple and create a slush, so don't omit it entirely.
You can also use water, but I suggest using juice to add extra fruit flavor to your slush.
Lower calorie version
If you'd like to make this drink lower in calories, I suggest substituting half of your frozen pineapple with ice. This will give your drink a slushy/icy type texture.
Drink garnishes
I serve my pineapple rum slush in a highball glass like these, but feel free to use what you have on hand. Pineapple chunks, orange slices, or mint leaves make a great garnish.

Can I make this ahead and freeze it
Hi Terry, I haven't tried freezing this recipe, so I can't say for sure. If you give it a try, let us know how it goes!
I freeze most of my slushy drinks. They all do fine.
I just made this per the recipe and it was amazing. The only thing I had to change was the rum. The only rum I had was a citrus rum. It turned out great...I will be making this again! ☺️
Citrus rum sounds great, glad you enjoyed the recipe!
Nice
Made a batch last night, turned out great! I used fresh pineapple that I froze beforehand, I think that helped give it more flavor using fresh ripe pineapple. Doubled the rum and it was still a good consistency!
Can I substitute the coconut water with coconut rum?
You can use coconut rum instead of the rum, but 3/4 cup of rum might be a bit strong if you replace the coconut water with it. You can also use water or pineapple juice instead of the coconut water. It's there to add a little liquid to the frozen pineapple, so it will blend easily.
Thanks, I think I'll try club soda first.
I use pineapple juice and pineapple rum.
That sounds delicious!
Looks delicious, but what can I use in place of coconut water? I just cannot stand the taste of anything coconut, but I'd really like to make these.
You could use pineapple juice, any flavor of club soda, or even plain water. The coconut water does give the slushies a tropical flavor, but it's mainly included to get the correct consistency when blending 🙂
