🥄Ingredients & Equipment
Keto Simple Syrup is inexpensive and easy to make with just two simple ingredients.
- Keto Sweetener – Choose your favorite zero calorie sweetner with no carbs to make your keto simple syrup. Monk fruit makes the best syrup, but any granulated sweetener will work based on your preference.
- Xanthan Gum – OPTIONAL – Since keto sweetener doesn’t thicken like regular sugar, xanthan gum can be used to create a syrup that is close in texture. You do not need to use this, but just keep in mind that the syrup will be very watery if you dont. If you are using allulose, you do not need a thickening agent.
- Filtered Water – It’s best to use a filtered water to make syrups to ensure that the taste is as fresh as possible.
Equipment
- Saucepan – to boil the water to dissolve the brown sugar in.
- Sealed Jars or Bottles – When sealed correctly, this syrup stores safely for a couple of weeks.
- Funnel – Using a funnel will make pouring the syrup into its storage container much easier.

📃How To Make Keto Simple
1️⃣ Add ingredients to saucepan:
In a small saucepan, add water, xanthan gum (unless using allulose), and granulated keto sweetener. Turn the heat to medium. Stir well.
2️⃣ Continue stirring:
Continue stirring over medium heat until the sweetener is dissolved completely (about 5 minutes). The liquid does not need to come to a boil in order for the sugar to dissolve.
3️⃣ Let cool:
Once the sweetener is dissolved, remove the saucepan from heat and let cool for at least 10 minutes.
4️⃣ Store:
Using a funnel, pour cooled keto simple syrup into sanitized jars or bottles that can be sealed with a lid.
🌟Recipe Tips
For the best tasting simple syrup, use filtered water.
To prevent spilling hot liquid, be sure to let the syrup cool for at least 10 minutes before funneling the syrup into containers.
The container you use (whether it be a glass jar, plastic bottle, etc.) should be sanitized first to prevent bacterial growth.
