Pineapple rum slush is a smooth and sweet alcoholic beverage that's made with just three ingredients in a blender. This refreshing tropical drink is perfect for lounging poolside this summer.

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, then 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
- Pineapple - You'll need one pound, or 16 ounces, of frozen cubed pineapple. If you have fresh pineapple on hand, you'll want to freeze it first. The frozen pineapple is what gives this drink its thick, slushy texture.
- Rum - Use your favorite - dark rum, coconut rum, clear rum - or you can substitute with vodka or tequila if that's more your style.
- Coconut water - can be substituted with pineapple juice or orange juice.
Best rums to use
The type of rum you choose for your cocktails is entirely up to you. I suggest choosing a brand of rum that you know you'll enjoy.

Their list includes rums like Probitas, which they recommend for daquiris and mojitos, as well as Don Q Gold, which goes well in pina coladas. Either of these would work well in a pineapple rum slush!
How to freeze pineapple
If you have fresh pineapple on hands, it's easy to freeze for this recipe. We need frozen pineapple because fresh pineapple won't create that thick, slushy texture when blended.
Slice your pineapple into chunks and spread onto a parchment/wax paper lined baking sheet (one that will fit into your freezer). Freeze for a few hours or overnight, then transfer to a freezer safe container to store until ready to use.
Blending tips
- Add the liquid ingredients first, then the frozen pineapple. Liquid at the bottom helps the blender process the frozen ingredients.
- Seal tightly with a lid and blend until the consistency is smooth and creamy.
- If the drink looks too thick, add more coconut water.
Coconut water substitutes
Don't like or have coconut water on hand? Here are a few substitutes:
- Pineapple juice
- Orange juice
- Coconut milk
Lower calorie version
If you'd like to make this drink lower in calories, substitute half of the frozen pineapple with ice. This adds a more slushy/icy texture.
Garnishes
- Pineapple chunk
- Orange slice
- Lime wedge
- Mint leaves
- Paper umbrella
- Maraschino cherry

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 🙂
