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 sugar substitutes.
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.

0I tried this but after it sat for awhile, it crystallized again. I did boil for the proper time so I’m not sure what I did wrong. I’d appreciate iate your thoughts. Thank you
Wholesome Yum D
0Hi Dawn, Did you use Besti sweetener? It should not crystallize, like others do.
Dawn
0So I boiled it again for a full 5 minutes and it stayed liquid!
Denise
0I decided to dry some fresh cranberries so I could sweeten them myself; the recipe I found called for simple syrup, so I made it using this recipe. It tasted fine, but for some reason it did not work with the cranberries. I don’t know if I did something wrong — probably I did — but I suggest caution when using Besti for more adventurous applications. Or maybe just don’t try to dry your own cranberries.
Michelle Lajeunesse
0Can you substitute with monk fruit with erythritol?
Wholesome Yum D
0Hi Michelle, You can use erythritol, but it probably won’t dissolve as completely and could leave your simple syrup with a gritty texture. If you still want to replace the sweetener in this recipe, use my sweetener conversion chart to make sure you are using the correct amount.
Matthew Jones
0What can be done to thicken up some? Maybe nothing. I still don’t get xanthan gum. I tried Inulin. It is a soluble fiber from Jerusalem artichokes. Newbie here. Thanks in advance.
Maya | Wholesome Yum
0Hi Matthew, Depending on what you are using it for, for most uses (such as drinks) it’s not really necessary for it to be thick. I have not tried thickening this recipe with thickeners. If you’re looking for a keto simple syrup that has a thickness like a traditional one, try this one instead.
Robin Sullivan
0Can you add various flavors to this recipe? I love Hazelnut, Peppermint and Raspberry flavors in my coffee!
Wholesome Yum D
0Hi Robin, Yes, you could do that.
Heather L Mitchell
0Have you ever tried simmering with a cinnamon stick for a fall flavor? Just wondering if it absorbs well. I hate cinnamon chunks floating on top of my coffee! Lol
Wholesome Yum D
0Hi Heather, I have not tried that, but please let me know your results if you do try it.
Sandra Brundage
0How would I add heat/spiciness to my simple syrup?
Wholesome Yum D
0Hi Sandra, I have never tried that but if you do please let me know the results!
Anne Rossbach
0Sugar sub re- crystallized as syrup cooled. Had to throw away 1 cup of expensive (even more expensive these days) sugar substitute.
Maya | Wholesome Yum
0Hi Anne, Did you use Besti sweetener? That one will not crystallize, but others do.
Karin Chipman
0Thanks 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
0I 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
0Hi 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
0Can you use Monkfruit confectioner sugar instead of Allulose
Maya | Wholesome Yum
0Hi 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
0Can you use this monk fruit/erythritol sweetener to make a (not a drink but actual Kahlua)?
Wholesome Yum D
0Hi 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
0How long will it keep? Should it be refrigerated?
Wholesome Yum D
0Hi Margaret, The simple syrup should be kept in the refrigerator and should last about 1 month.
Soraya
0Hi
Could this syrup be boiled to make it sticky for granola bars
Wholesome Yum M
0Hi Soraya, I have not personally tested this, but it may work. Please share your results with us if you decide to try it!
Anna
0OMG – 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
0I love that you have a link to jump to the recipe!
Amana Issa
0Didn’t work! It tasted tart and powdery and crystallised almost immediately
Wholesome Yum M
0Hi 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
0Hi, 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
0Hi 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
0When 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
0Hi 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.
Wholesome Yum A
0Hi, 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
0Hi 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
0Can you make Keto simple syrup with fresh lavender flowers?
Wholesome Yum M
0Hi 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
0I 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
0Ty 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
0Hi 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
0Interesting! 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
0Hi 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.
Bob H
0I know this an older post but I just came across it. My question is; how Xanthan gum to use when making the above recipe? I’ve had mixed results using Xanthan.
Wholesome Yum D
0Hi Bob, I have never tried to use xanthan gum in this recipe.
Michael Stalker
0I’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
0Hi 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
0So 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
0Hi Ashley, Did you use allulose of erythritol in your simple syrup?
Astrid
0This 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
0Hi Astrid, I have not tried this, but it should work great! Enjoy.
Beth
0This is amazing! I love this recipe! Thank you!
