As a kid, my favorite thing ever was caramel syrup. I would always add it to frozen desserts and as I grew older, it was my favorite syrup for hot and cold beverages (especially a frappucino or milkshake). When I first started my health journey, it was easy to do, as I switched my typical syrup for their sugar free varieties. 

Instead of Torani, Starbucks, or Smuckers, which all contain tons of artificial flavors and ingredients, my homemade sugar free caramel syrup has been a savior.

Why I love this recipe

  • Natural flavors! No artificial sweeteners, no sugar, and no thickeners whatsoever.
  • Perfect taste and texture. The texture is smooth, thick, and perfectly silky. It smells and tastes like any good caramel and has a gorgeous caramel color.
  • It’s versatile. As a diehard caramel fan, I’ve been using it as the caramel in several of my recipes (hello, caramel ribbon crunch frappuccino!).

Ingredients needed

  • Butter. Unsalted and cubed butter. Always try to use butter from a block and not from a spread (tub), as the latter usually has added fillers and water that can make the final syrup slightly gritty. 
  • Allulose. The ONLY sugar free sweetener that will work properly for the syrup. Allulose mimics white sugar and does not crystalize at room temperature. Do not try using erythritol, monk fruit syrup, sucralose, or Splenda, as the caramel will become gritty. 
  • Heavy cream. Also known as thickened cream or double cream. 
  • Salt. Optional, but add this if you love a salted caramel kind of sauce. Alternatively, you can use salted butter!

How to make sugar free caramel syrup

Step 1- Melt. Add butter and allulose to a small saucepan and place it over medium heat. Once the butter has melted, whisk together the mixture for 5-6 minutes.

Step 2- Add cream and reduce the heat to low. Let the caramel syrup simmer for around 5 minutes while continuing to stir until it begins to thicken. Once it begins to thicken, remove it from the heat.

Step 3- Mix and cool. While the saucepan is off the heat, continue to stir it until it cools down to room temperature.

Arman’e recipe tips

  • You must constantly stir the caramel syrup throughout the entire cooking process. Because you are working with butter AND a sweetener, it’s very easy to burn the mixture accidentally. 
  • Do not overcook! The more time the caramel syrup remains over the heat, the thicker it becomes. Even though the syrup may look quite thin when you remove it from the heat, it will continue to thicken up as it reaches room temperature. 
  • If your caramel syrup is too thick, you can always microwave it for 20-30 seconds before using it. 

Storage instructions

Regardless of whether you store the sugar free caramel syrup in the refrigerator or the freezer, you may find it becomes quite thick and hard. To combat this, simply bring it to room temperature, and if it is still quite thick, you can gently reheat it. 

To store: Keep the syrup at room temperature, in a sealable jar or bowl. It will keep well for up to 4 weeks. If you’d like to keep it longer, you can store it in the refrigerator for up to 2 months. 

To freeze: Store it in the freezer for up to 6 months.

    This recipe sounds simple yet this caramel looks delicious. Thanks for the recipe.
    I just wanted to know if I can use coconut cream(thick part on top of coconut milk can) to make this? Also, can I use ghee instead of butter?
    Just trying to limit milk solids, I can tolerate ghee so hoping to make it almost vegan.

    Thank you 🙂

  2. I decided to try it with Lakanto’s monkfruit sweetener (which also contains erythritol) because I couldn’t find allulose , and it worked BEAUTIFULLY! It measures cup for cup, but since I don’t like when things are too sweet, I only used 3/4 of a cup in the recipe. It turned out slightly paler in colour compared to this one; but just as perfectly silky smooth and delicious, even once cooled down. The other difference is that in step one, I put it on low heat instead of medium, and increased to medium after adding the cream to help it thicken a bit. Cheers ya’ll!

    I love this recipe! I seecthat it says 1 carb per serving but I’d love to know precisely how much 1 serving is as I count carbs very closely. I could measure it all out and calculate it myself but if you happen to know it I’d appreciate the information! Thanks for the awesome recipe!

  4. I just finished making this and it is just great! I will add it to my creami vanilla ice cream. I also used this sweetener in the ice cream. This is first time I have used it, so far so good.

    Just exactly followed the recipe using salted butter instead of adding salt. The results were fantastic! I love this recipe.

  6. The short answer is no. Allulose, not cellulose, is the only keto friendly ask natural sugar substitute that will act the way regular sugar does when using it… This means that it will brown properly this making the caramel flavor needed in this recipe. If you buy allulose, available in granulated and liquid form, you can use it instead of the others in all recipes. It is a true sugar replacement that is measured one to one… So stop buying stevia, monk fruit, swerve, etc… And just stick with allulose. I have yet to find a recipe it doesn’t work well in .

    1. Is there absolutely no way to use stevia in this? I live in South America and it is literally all I can find thanks!!!🫶

  7. Can I use erythritol instead of cellulose. Every recipe seems to call for a different sugar and they are expensive so I would rather use one up before I buy another

    1. It really meeds Allulose because all the other sugat substitutes crystalixe and what a mess you get. Ask me how I know. I tried a dozen attempts to get sugar free caramel or other simple syrups before discovering Allulose! It’s great in anything that needs sweetened that you cook or bake. No grittiness at all and it stays that way after it cools. Use it in cheesecakes, puddings, syrups. It has endless uses and you’ll find you use it a lot. It’s worth the money and I am money tight, so I’m not advocating you spend money that will go to waste. It’s available in many grocery stores now too. You can get a pound of Allulose at Walmart for under $9 and you’ll be able to bake all kinds of goodies with that. It’s called RXSugar. Just don’t get an Allulose baking blend as it has all kinds of other sugars that will mess up your baking. That’s just evil of them to sell to unsuspecting cooks. You do use a little more as it isn’t as sweet as some other subs. Just follow any of Bog Man’s recipes and you won’t go wrong. The guy is a master in the kitchen!

        It was great-tasting, but my caramel was more solid than liquid. It was very difficult to mix into my iced coffee, because it stayed solid. I’m wondering if I did something wrong.

      2. 5 stars
        Just pop a couple T it in the microwave for 10-15 sec before serving. Are you storing it at room temp like instructed? It should be able to drizzle it then. But if you are trying to mix it, heat and add before you add your ice.

      I will make this next week. Your recipie looks great. I have made caramel before, but with regular sugar. Thanks Barb and I’ll let you know how it goes.
