Keto Simple Syrup Recipe (Sugar-Free) - Stem and Spoon (2024)

This keto simple syrup recipe is a delicious, sugar-free version of traditional simple syrup and it's quite... simple!

With only two ingredients and five minutes required, this easy, sugar-free syrup is a great go-to when you're in need of a low-glycemic liquid sweetener.

This keto simple syrup is versatile, super easy to prepare, and it will store well in the refrigerator for up to a month. Whether you're on the keto diet, looking for diabetic-friendly liquid sweeteners or you're trying to reduce sugar all around, this sugar-free simple syrup recipe is a keeper.

what is simple syrup?

Traditional simple syrup is a liquid sweetener made with equal parts water and regular sugar, sometimes flavored depending on what it will be used for.

The most popular recipe is to mix one cup of sugar with one cup of water. It's essentially sugar water- cooked until the sugar dissolves- and perhaps its most common use is to sweeten cold drinks and co*cktails since it mixes easily into the liquid.

why this recipe works

This keto simple syrup recipe is made the exact same way, but without the sugar, of course. Instead, you can create a homemade sugar-free simple syrup with allulose and water.

The great thing about simple syrup is it can be the base for any flavor you'd like! My version features a splash of vanilla extract, but you can also steep the simple syrup with ingredients like cinnamon sticks, a vanilla bean, fresh ginger, culinary lavender buds, berries, mint leaves, rosemary, etc.

This simple recipe opens up a whole new world of making homemade, low carb co*cktails that rival their sugary counterparts.

This keto syrup is:

• quick and easy to make, with only two ingredients required and a five-minute prep time
• versatile- use it to sweeten drinks, co*cktails, sauces, smoothies and more
• low glycemic with zero net carbs- keto, low-carb and diabetic friendly
• a keto sweetener that is a healthier alternative to regular simple syrup with a sweet, clean taste

about the ingredients

Allulose is a natural, pure sugar found in fruits like fig, kiwi and raisins. Due to the way the sugar alcohol is processed in our bodies, it has low (or no) impact on blood sugar levels. It's a low-carb, keto-friendly sweetener that is appreciated for its nice, clean taste.

For this keto simple syrup recipe you'll need these two (plus optional third) simple ingredients:

• granulated allulose
• filtered water (cold or at room temperature)
• vanilla extract (optional)

Allulose isn't as sweet as sugar so instead of a 1:1 water/sweetener ratio, you'll need an extra ⅓ cup of the low carb sweetener.

While I often prefer to use monk fruit sweetener as a sugar substitute, I tend to choose allulose over a granulated erythritol blend when it comes to drinks and sauces. That's because allulose dissolves really well and it can hold up to hot or cold without crystallizing (unlike erythritol).

This is the biggest reason why allulose is a great replacement for sugar when it comes to liquids like drinks and sauces. I've used it to make sugar-free limeade, bourbon chicken, keto lemon curd and keto chocolate sauce.

tips for the best results

This recipe is so easy to follow, but here are a few tips that might help you out.

• To add different flavor agents, follow the recipe process and then add the flavor ingredients in at the end. Cover the saucepan with a lid and let the ingredients steep in the simple syrup until it is infused with the flavor. Note: The amount of time will vary based on whichever flavor agent you're using.

• If you'd like the syrup to be a bit thicker, you can also vigorously whisk in a pinch of xanthan gum (no more than ⅛ teaspoon). Xanthan gum is a gluten-free thickening agent often used in sauces and baking. Make sure to whisk it in really well to avoid any clumps forming.

• To store this keto simple syrup, seal the jar with a lid and store in the refrigerator for up to one month.
