This sugar-free slushie is the ultimate way to cool down fast on a hot day. The keto slushie drinks here combine real fruit with a natural sweetener for a two-minute refreshment that won’t weigh you down. (And you can even use similar ingredients in this short recipe to make sugar free sorbet and keto frozen yogurt!)
The secret to making the best sugar-free slushie starts with making it sweet: Besti Powdered Monk Fruit Allulose Blend is the perfect choice, since it dissolves smoothly into cold drinks and has a flavor just like sugar — all with zero net carbs! (Many other sweeteners can make drinks gritty or just settle to the bottom.)
Why You’ll Love This Keto Slushie Recipe
- Sweet, fruity taste
- Smooth texture
- Made with real fruit (just 3 easy, healthy ingredients!)
- 2 minutes from start to finish
- No fake colors, drink syrup, or artificial flavors
- The perfect quick treat for hot summer days!
Ingredients & Substitutions
This section explains how to choose the best ingredients for sugar-free slushies, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.
- Frozen Berries – Use a mixed berry blend, or choose a single type of frozen, low sugar berries. Strawberries, raspberries, blackberries, and blueberries are all great keto fruits for a slushie.
- Club Soda – Gives this slushie a smooth and airy consistency that’s easy to sip. Any kind of plain sparkling water will work here, as long as it’s sugar free.
- Besti Powdered Monk Fruit Allulose Blend – This sweetener dissolves smoothly into cold drinks, so your sugar-free slushie is never gritty! Other granulated or powdered sweeteners are not recommended, as they won’t dissolve completely. You could also use keto simple syrup, but the consistency would be a bit thinner.
How To Make Sugar Free Slushies
This section shows how to make a sugar free slush or slurpee, with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.
- Combine. Add berries, club soda, and Besti Powdered Monk Fruit Allulose Blend to a high powered blender.
- Blend. Blend the sugar-free slushie recipe until it reaches a smooth consistency. Enjoy immediately.
Variations
- Swap the fruit – Although the berries below have lower sugar compared to many keto fruits, you can swap in any frozen fruit that fits your lifestyle or keto macros — peach, pineapple, mango, or watermelon would be delicious choices if you can spare a few extra carbs.
- Add herbs – Mint is a classic addition, but other combinations (such as basil or rosemary with frozen strawberries) would be refreshing as well.
- Mix up the flavors – Add spices like cinnamon, vanilla, or ginger to make flavors in this keto friendly slushie pop!
- Add tang – A splash of lime or lemon juice (or citrus zest) can help bring out the sweetness in the fruit.
Storage Instructions
This sugar free icee tastes best when served right away, so refrigerating or freezing is not recommended. You might be able to keep it in the freezer for 10-20 minutes to keep it cold, but anything longer than that will change the consistency.

0Love, love, love this simple recipe! I used mixed berries, and it was delicious. I would love to make a Slushie without fruit too. Maybe with Mio and ice? Do you have a recipe for something like this. I’m not good at figuring out what quantities to use, etc.My creations always end up bland, or too sweet, or too icy, etc. Thanks in advance!

0I used only frozen wild blueberries (3 cups) and the 1/4 Besti Allulose granular, along with one can of diet Canada Dry ginger ale. Very refreshing, delicious and sweet enough as the diet soda is sweetened which made up for the lack of monkfruit and the extra blueberries. Made two large tumblers filled to the top for my wife and myself!
