Creamy, tropical, and completely sugar-free, this keto frozen pina colada is the drink I make all summer long poolside. Full-fat coconut milk, rum, and a hit of extract give it that classic tropical flavor without any of the sugar.
I started making this frozen cocktail when I first went keto and realized how much I missed tropical drinks on hot days. The sugar in a traditional version is almost entirely from pineapple juice, so I swapped it out for full-fat coconut milk and a teaspoon of pina colada extract. That extract is what makes the whole thing work. Guests think there’s a sugary mixer involved. When I show them the coconut milk and monkfruit, they don’t believe me.
The texture question comes up a lot, and I’ve landed on a firm answer: coconut cream makes a noticeably better drink than coconut milk. I switched after testing both side by side, and the difference is real. Coconut cream gives you a thicker, more frozen-cocktail consistency that holds its slushy texture longer, especially when you’re sitting outside in the heat. Coconut milk still works, but once you try the cream version, going back feels like a downgrade. If you’re using canned coconut milk, grab the full-fat unsweetened kind. The lite versions have more sugar and thin the whole thing out.
For a party, I scale this into a pitcher: double or triple the recipe, blend in batches, and pour into a large pitcher with extra ice to keep it cold. Two pitchers disappeared at a spring break gathering at my house and nobody could tell it was sugar-free. My strawberry slushy cocktail is another crowd-pleaser if you want variety on the drink table.
Rum is zero carbs, which makes it one of the easiest spirits for a low carb lifestyle. I use white rum for the classic flavor, but coconut rum works too (just check the label for added sugar). If you’re building out a cocktail rotation, my strawberry daiquiri and mojito use the same approach: real spirits, sugar-free mixers, and enough flavor that nobody asks if it’s a diet drink. The Blue Hawaiian is another tropical option if you want to keep the island theme going.
One thing I tell everyone: start with 3 tablespoons of sweetener, not the full quarter cup. Monkfruit and erythritol brands vary wildly in sweetness intensity, and it’s way easier to add more than to fix a drink that’s too sweet. Taste after blending, then adjust from there. I’ve been making these long enough that I eyeball it now, but 3 tablespoons has been the most reliable starting point I can give.

Coconut cream vs. coconut milk — which makes a better base?
I've tested both back to back and coconut cream wins every time. The drink comes out thicker, holds its slushy texture longer in the heat, and the coconut flavor is more pronounced. Coconut milk still works if that's what you have, but I always reach for the cream now. If your can of coconut milk has been in the fridge, the thick layer on top is essentially cream, so scoop that out and use it.
How do I make a pitcher for a party?
I double or triple the recipe and blend in batches since most blenders can't handle the full volume at once. Pour each batch into a large pitcher with extra ice to keep everything cold. I've served this at pool parties and the pitcher empties fast. Two batches fills a standard drink pitcher and serves about 6 people.
Can I use heavy cream instead of coconut milk?
You can, and it makes the drink richer and more indulgent. I've tried heavy whipping cream as the base, and the texture goes almost milkshake-thick. It's not dairy-free anymore, but if dairy doesn't bother you, it's a solid swap. Use the same amount as the coconut milk called for in the recipe.
How much sweetener should I actually use?
I always tell people to start with 3 tablespoons instead of the full quarter cup. Monkfruit and erythritol brands are wildly inconsistent on sweetness intensity, and I've had batches where a quarter cup was way too sweet. Blend with 3 tablespoons first, taste it, then add more a teaspoon at a time. After making this dozens of times, I eyeball it now, but that starting point has been my most reliable advice.
Can I make this ahead of time and freeze it?
I've frozen batches in ice cube trays and then re-blended them when I'm ready to serve. The texture is slightly more icy than a fresh blend, but it's still good. For same-day prep, I blend everything a few hours ahead and store it in the freezer for 30 to 45 minutes. Pull it out when the edges start to firm up and give it one more quick blend.
Are there hidden sugars in the extract?
Some brands, yes. I've seen extract bottles with sugar alcohols, corn syrup, or even high fructose corn syrup listed in the ingredients. Always flip the bottle and check. The pure extract versions are what you want. If you can't find a clean one, pineapple extract works as a substitute, or skip it entirely and let the coconut flavor do the work.
How do I get a thicker, creamier texture instead of slushy?
I use more coconut cream and less sparkling water. One of my readers replaced the sparkling water entirely with the other half of the coconut milk can, and the texture shifted from slushy to frozen-cocktail thick. I've done the same thing and it works. You can also use a bit less ice for a creamier, less icy result.




Swapped the sparkling water for the other half of the coconut milk can. Texture went from slushy to more of a frozen cocktail. Worth trying if that's your thing.
Made this probably six or seven times now. Switched to coconut cream instead of coconut milk whenever I have a can open. Comes out noticeably thicker and the slushy texture holds up longer, which I noticed sitting outside on the first real warm evening. The LaCroix was the part I wasn't sure about, but it lightens the whole thing just enough so it doesn't feel heavy. Going back to full coconut milk feels like a step down.
The coconut cream difference is real. Thicker base, and the texture holds way longer especially when it's warm out. Hard to go back.
Third time making this and I finally landed on the right ratio: a little less rum and a bit more coconut cream. The texture goes from slushy to almost creamy and it's the version I'll stick with.
Yeah, less rum shifts the texture faster than you'd expect. The coconut cream does the rest. Third time is usually when it clicks.
The coconut milk base is so much better than I expected, genuinely rich and creamy without feeling heavy. My one note is that a full quarter cup of sweetener ran a little sweet for me (I'd start at 3 tablespoons next time and adjust from there), but the coconut flavor itself is spot-on and the piña colada extract really pulls everything together. Solid spring drink.
Sweetener brands are wildly inconsistent on intensity. 3 tablespoons first, taste, then add from there.
Made a pitcher for spring break last weekend and my friend who always orders the sweetest thing on the menu kept sneaking back for more. She was convinced there was a sugary mix in there. When I showed her the coconut milk and monkfruit she didn't believe me. Zero carbs, two pitchers gone.
The monkfruit reveal gets people every time. The piña colada extract is what really does it (that's what makes it taste like there's a sugary mix in there).
I'm so greatful for you! Thank you for all you do! I love watching your videos, you've helped me succeed. Thank you ?
Love hearing that. Pour yourself one of these to celebrate - 0.4g net carbs, you've earned it.
