Keto Sugar Free Slushie Recipe
Yes, you can make a sugar free slushie at home! This keto slushie uses just 3 natural ingredients for a sweet, fruity, icy drink.

This sugar free slushie is the ultimate way to cool down FAST. The keto slushie recipe here combines whole fruits with a natural sweetener for a two-minute refreshment that won’t weigh you down. (You can also use similar ingredients to make sugar free sorbet!)
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!
Sugar Free Slushie Ingredients
This keto slushie needs just 3 ingredients, but every single one counts!
- 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 – Don’t just use regular water… 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. You could also use keto simple syrup, but the consistency would be a bit thinner.
The ingredient amounts are on the recipe card below.
How To Make Sugar Free Slushies
- Combine ingredients. Add berries, club soda, and Besti Powdered Monk Fruit Allulose Blend to the blender container.
- Blend. Blend the slushie until it reaches a smooth consistency.
Keto Slushie FAQs
Are slushies keto friendly?
Most slushies are not keto friendly, as they contain added sugar. Making keto slushie drinks at home is the best alternative, since you can cut out the sugar altogether!
Do slushies have carbonation?
Not every homemade slushie recipe uses carbonated water, but it helps make every sip more airy and fluffy.
Storage Instructions
This keto slushie recipe tastes best when served right away.
Can you freeze a keto friendly slushie?
Avoid freezing sugar free slushies to enjoy later. 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.
