The Ingredients
Skip down to the recipe card to see the nutrition facts and exact measures of ingredients needed to make this sugar free caramel sauce recipe.
Keto Caramel Syrup is super easy to make at home. It is suitable for a low carb, keto friendly diet. It is both sugar-free and gluten free.
All you need are 3 ingredients
Cream – I use a thickened or heavy whipping cream rather than pure thin cream.
Butter – I just use regular salted butter.
Sweetener – I use allulose for this recipe. Its rich caramel colour comes from using the right sweetener. Allulose is the ONLY keto sweetener that will caramelise and turn it into caramel. Other low carb sweeteners will recrystallise e.g. erythritol, monk fruit sweetener. Xylitol will make keto condensed milk, which is great, but it will not caramelise.
What is Allulose?
Allulose is a naturally occurring sugar found in wheat, figs, raisins, maple syrup and molasses.
It is very close to the same level of sweetness and properties for baking and confectionary as regular sugar but without carbs. In its natural state, it is found in small quantities and is processed to resemble a regular-looking sweetener.
It is classed as a natural keto friendly sweetener and is not a sugar alcohol. Allulose is recognised by the FDA as a safe food. However, here in Australia and in some other countries has still not been approved by our food authorities.
Due to allulose’s ability to caramelise and not crystallise this recipe is suitable only with allulose as the low-carb sweetener.

How to make Sugar Free Caramel Syrup
Step 1. Add cream, butter, and allulose sweetener to a small saucepan over medium heat. Bring to a boil then turn down to a simmer.
Step 2. Cook, stirring occasionally, for 40-50 minutes until mixture has begun to thicken. Remove from the heat and leave to cool at room temperature for 30-45 minutes. Pour into a jar or bottle and transfer to the fridge. The caramel will thicken more upon chilling.
Sugar free caramel syrup can also be made in the Thermomix. I have made this many times in the Thermomix and it is so easy. The syrup will still be quite runny when the timer is finished, but thickens when cooled. See the recipe card for tips using your Thermomix or similar thermal cooker.
How To Serve Sugar Free Caramel Syrup
You can make and flavour this keto syrup in quite a few ways. I know many of our readers love Skinny Syrups and Torani Syrups for their coffee and desserts, or Monin Caramel Syrup. In my opinion, this is better. It less expensive and more versatile.
Thin out the caramel over gentle heat or with a little warm cream or water if you want a thinner syrup.
For copycat Starbucks frappucinos or shakes try adding spice or spice blends like our Pumpkin Spice Blend to make Keto Pumpkin Frappucinos.
Sugar free caramel sauce for coffee – mix as much as you like in coffee to sweeten.
Mix with nuts, seeds or popcorn (not low carb) for a delicious sugar free sweet topping.
Cheesecake – mix the whole batch with 500g of cream cheese for the ultimate keto caramel cheesecake. Yummo, now there is a great idea!
Sugar free caramel syrup for ice cream – Pour warm over ice cream for an amazing sugar free fudge sauce better than McDonalds.
Frequently Asked Questions
Erythritol will crystallise and go crunchy. Xylitol will make a syrup/sauce but the results are not a caramel but more thick creamy sauce.
I have kept mine up to 1 month in the fridge. In saying that, it does depend on the temperature in the fridge and how often your fridge door is open (hello kiddos).
Some say yes, but I say just keep it in the fridge. It can separate when taken back out of the freezer.

Variations
1. Salted Caramel
Once your caramel is finished cooking, stir in ½ to 1 teaspoon of flaky sea salt (or to taste). It adds a beautiful balance to the sweetness and gives it that rich, indulgent flavor that’s perfect over keto ice cream or stirred into coffee.
2. Vanilla Caramel
Add 1 to 2 teaspoons of pure vanilla extract right at the end of cooking. This simple touch gives it a smooth, almost custard-like warmth that works beautifully in desserts or drizzled over pancakes.
3. Spiced Caramel
For a cozy twist, add ½ teaspoon ground cinnamon and a pinch of nutmeg or allspice while cooking. It’s dreamy in autumn-inspired treats or even as a dip for low carb apple-flavored snacks.
4. Dairy-Free Caramel
Swap the heavy cream for canned coconut cream and use a dairy-free butter alternative (like Nuttelex or coconut oil). Alternatively, you can leave out the butter altogether and make it the caramel syrup similar to a Filipino coco jam recipe. The coconut adds a subtle depth of flavour, and it still thickens up beautifully into a silky, spoonable caramel.

Hi Megan,
I’m in Australia. Please advise which website I can order allulose.
Thanks.Hi Tracey, I am located in Australia too. There is a link provided in the recipe to the iHerb product I use. iHerb deliver to Australia and have a low-ish order limit for free shipping too.
This is surprisingly easy to make and perfect on keto ice cream! Will definitely be making this again!
This is a delicious, creamy caramel syrup! We served it over ice cream and no one realized it was sugar free until I told them. Naturally everyone then went for a second serving of ice cream with more caramel syrup. Thanks for the recipe!
This caramel sauce is crazy good! We used it on sundaes and everyone loved it!
