This homemade keto simple syrup can be used in so many different ways and requires just two ingredients: Besti + water! Not only is sugar-free simple syrup incredibly easy to make, but the particular sweetener used here makes it the best low carb simple syrup recipe. It dissolves effortlessly and tastes just like a sugar simple syrup. Use it for all of your keto cocktails!
What Is Simple Syrup?
Simple syrup is a slightly viscous, clear syrup, made of a 1:1 solution just sugar and water. Its main purpose is for use in drinks, but there are other ways to use it as well.
Obviously, the sugar makes it not-so-keto-friendly, which is why we needed our own low carb simple syrup recipe without sugar!
How To Make Keto Simple Syrup
This sugar-free simple syrup recipe couldn’t be easier! Ok, get ready….
- Combine water and Besti Monk Fruit Sweetener in a saucepan. It will be cloudy at first.
- Heat until dissolved. Bring to a boil, then simmer and stir frequently, until the sweetener is completely dissolved. It’s ready when it’s completely clear!
Low Carb Simple Syrup FAQs
Can you make sugar-free simple syrup?
Yes, sugar-free simple syrup is possible and it works really well – if you use the right sweetener.
Traditional simple syrup is made with a 1:1 ratio of sugar to water and our best sugar-free simple syrup is made in the same way. A 1:1 ratio of Besti to water!
Why use simple syrup vs just a granulated sweetener?
Because it mixes better! Stirring sugar into something can leave some of it sitting at the bottom, and this is even more true with keto sweeteners.
Which brings us to the next important question…
Can you use a different sweetener?
Yes and no.
Monk Fruit Allulose Blend is the absolute best keto sweetener to use for simple syrup, for two very important reasons:
- It dissolves like sugar. Most keto sweeteners, including erythritol and most brands of monk fruit, will not dissolve well.
- It tastes like sugar. There is no aftertaste that you might find with some others.
If you want to try it with a different sweetener, another option that would dissolve well is allulose. You’d need more of it, about 1 1/3 cup.
If you still want to attempt to make this sugar-free simple syrup using an erythritol-based sweetener, start with a powdered version. It still does not dissolve as well, but better than granulated.

Can you thicken sugar-free simple syrup?
Yes, you can. I left out any thickener because for the most common use (keto drinks!), it’s not necessary.
If you want to thicken it, just sprinkle on some xanthan gum and whisk vigorously, like I do for my keto maple syrup.
Sugar-Free Simple Syrup Storage Instructions
Can you make homemade sugar-free simple syrup ahead?
Yes, you can and should make keto simple syrup ahead.
Does simple syrup need to be refrigerated?
Yes, since this is a homemade keto friendly simple syrup and has no added preservatives, it’s best kept in the fridge. It will last at least 1 month.
Can you freeze sugar-free simple syrup?
Yes! It will last a very long time, at least a year.

Interesting! It doesn’t appear very thick. Does it thicken up a bit as it sits, or does it go on to be very watery?
Wholesome Yum M
Hi Katie, Yes. Xanthan gum needs heat to activate it. It will thicken slightly while cooking but will turn to a thicker syrup consistency once it cools.
Michael Stalker
I’ve made other keto-friendly simple syrup. I find that the sugar substitute recrystallizes. How does Besti hold up? Also, do you know if I could powder the granulated version in a Vitamix? Thanks.
Wholesome Yum M
Hi Michael, Besti Monk Fruit Allulose Blend dissolves really well in liquids, so as long as it fully dissolves while hot, you shouldn’t need to run it through a blender. Also, it doesn’t crystallize, so it will store in the fridge really well for the long term. Enjoy!
Astrid
This sounds great. I was wondering if I could add a couple of sticks of cinnamon while the mixture is boiling to make a cinnamon flavor syrup to add to my Frappuccino later on.
Wholesome Yum M
Hi Astrid, I have not tried this, but it should work great! Enjoy.
Beth
This is amazing! I love this recipe! Thank you!
