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.

Sugar sub re- crystallized as syrup cooled. Had to throw away 1 cup of expensive (even more expensive these days) sugar substitute.
Maya | Wholesome Yum
Hi Anne, Did you use Besti sweetener? That one will not crystallize, but others do.
Karin Chipman
Thanks for all of your recipes! I just want to put out there that not everyone can tolerate the amount of Allulose in this simple syrup. I had a miserable night running to the potty after trying. Everyone may want to have a small batch test to see how they tolerate it before drinking an entire drink to make sure they aren’t one of the unlucky few who can’t really use Allulose. I’m really sad that I’m included in this group as the simple syrup tasted incredible.
Karen Tharp
I love your KETO Simple Syrup! I ordered 2 bottles recently. I have made your sugar free KETO ketchup recipe and I loved it. I used powdered monkfruit last time but I would like to substitute that with your simple syrup. What are the ratios of your simple syrup to regular sugar? How much should I add?
Wholesome Yum D
Hi Karen, Using liquid sweetener in recipes that call for powdered or crystallized doesn’t really translate well. I think the simple syrup would make the ketchup too runny and not thick like you would want.
Christiane
Can you use Monkfruit confectioner sugar instead of Allulose
Maya | Wholesome Yum
Hi Christiane, Besti (used in this recipe) is a monk fruit sweetener. 🙂 I don’t recommend other brands of monk fruit, as they use erythritol as a bulking agent and won’t dissolve well.
Nancy
Can you use this monk fruit/erythritol sweetener to make a (not a drink but actual Kahlua)?
Wholesome Yum D
Hi Nancy, I am not exactly sure what you are asking to make but if a recipe calls for simple syrup this keto version can be used in its place.
Margaret
How long will it keep? Should it be refrigerated?
Wholesome Yum D
Hi Margaret, The simple syrup should be kept in the refrigerator and should last about 1 month.
Soraya
Hi
Could this syrup be boiled to make it sticky for granola bars
Wholesome Yum M
Hi Soraya, I have not personally tested this, but it may work. Please share your results with us if you decide to try it!
Anna
OMG – SO Easy! I’ve ordered all of your sweeteners and mixes and they are the BOMB.
However, I ran out of simple syrup and today is skinny margarita day, so I gave this a try (using the Bestie crystalized allulose sweetener you recommend).
HAPPY SKINNY MARGARITA TIME FOR ME!
Keep up the great work!
Lola
I love that you have a link to jump to the recipe!
Amana Issa
Didn’t work! It tasted tart and powdery and crystallised almost immediately
Wholesome Yum M
Hi Amana, Sorry this recipe didn’t turn out as expected. What kind of sweetener did you use? Erythritol won’t dissolve as well and will crystalize in the bottle. The best choice for a keto simple syrup is pure Allulose or (ideally) Besti Monk Fruit Allulose Blend.
Rachel
Hi, curious why in this simple syrup recipe you list Besti Monk Fruit Allulose Blend (crystalized), while in your lemonade recipe, to make the simple syrup you list the Besti Powdered Monk Fruit Allulose Blend. BTW, I made this with your bottled simple syrup and it was delicious 🙂
Wholesome Yum M
Hi Rachel, I make this simple syrup with either granulated or powdered. Because Besti Monk Fruit Allulose fully dissolves in liquid, they will both work just the same.
Dale C Wiggins
When you say 1:1, is that by weight or by volume? I have some Lakanto Monkfruit sweetener (granulated) that I was gonna try with this. I’m not sure if that brand will not work well. If so I’ll try the Besti. Thanks!
Maya | Wholesome Yum
Hi Dale, 1:1 sugar replacements typically refer to volume, though weight is pretty similar as well. I don’t recommend Lakanto for making simple syrup – it doesn’t dissolve well and will be gritty, or not sweet enough with the sweetener settling at the bottom. I cover sweetener alternatives in the FAQ in the post above, but long story short, Besti Monk Fruit Allulose Blend is the best sweetener for making a simple syrup. It’s one of very few that would truly dissolve properly. Also, I now have a premade sugar-free simple syrup in a bottle here.
Amanda
Hi, I have been trying to find a keto divinity recipe for a long time, which of course requires you to cook sugar and corn syrup to a hard crack stage, then pour it into some beaten egg white mixture. Do you happen to know if this syrup reaches a hard crack stage and could be used for such a purpose?
Wholesome Yum M
Hi Amanda, I’m sorry this is not something I have experimented with yet. I will be sure to add it to my list to try soon.
Elise Bosch
Can you make Keto simple syrup with fresh lavender flowers?
Wholesome Yum M
Hi Elise, I have not personally tried this, but I don’t see why it wouldn’t work. Dried or fresh should work well. Enjoy!
Karen
I added lavender to it and it is great!! I used all monk fruit and it crystalized half way, so I stuck it in the freezer. I will try it will pure allulose next time.
Mary
Ty for posting this recipe, I am thinking of using it as a replacement for the fiber syrup that you use in your AMAZING granola bar recipe. What do you suggest I do to modify this recipe to make it sticky like the syrup? Thanks!
Maya | Wholesome Yum
Hi Mary, I think this homemade simple syrup would be too thin to use in the keto granola bars. Instead, I think my keto maple syrup or pre-made simple syrup could work very well, as they have a thicker consistency – I just haven’t tried that yet. Let me know if you do!
Katie
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!
Ashley Bourgeois
So just tried this but made it a 2:1 ratio so would need to use less and it all crystalized in the fridge….is it because of the 2:1 ratio?
Wholesome Yum M
Hi Ashley, Did you use allulose of erythritol in your simple syrup?
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!
