Sugar Free Caramel Syrup

If there is one flavor for desserts, beverages, or treats that I am obsessed with, it is caramel. Give me anything caramel flavored and I’ll be the biggest fan. 

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. 

Torani, Starbucks, and Smuckers have all been pioneers in the sugar free caramel syrup game. I remember when I first started my health journey, I used all three brands in various ways. Whenever I ordered Starbucks, instead of their caramel syrup, I switched to their sugar free option. At home when I made my own coffee, I added Torani sugar free syrup. And whenever I had a scoop of ice cream for dessert, I’d drizzle Smuckers sugar free caramel flavored syrup.

While this was all great at the start, I soon started getting stomach pain and digestive issues whenever I enjoyed these things. This had to come down to what was used to make these artificial syrups!

What is in sugar free caramel syrup?

A quick glance at both the Smuckers and Torani syrup brands shows some worrying ingredients in them. Some of these include maltodextrin, maltitol syrup, sorbitol AND sucralose. For those unaware, these are all artificial sweeteners than can cause havoc with anyone’s digestive system. Luckily, I have a solution to make your own homemade syrup without any of the junk!

This sugar free caramel syrup recipe ticks all the boxes. It’s made with just 3 ingredients and NOTHING artficial. No artifical sweeteners, no sugar, and no thickeners whatsoever. The texture is smooth, thick, and perfectly silky. It smells and tastes like any good caramel, you’ll be adding it to everything! 

What I love about this syrup is how versatile it is- As a diehard caramel one, I’ve been using it as the caramel in several of my recipes, including a caramel tart, chocolate caramel cake, and salted caramel brownies!

How do you make a sugar free caramel syrup?

The Ingredients

  • 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, 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! 

The Instructions

Start by adding the butter and allulose into a small saucepan and place it over medium heat. Once the butter has melted, whisk together the mixture for around 5-6 minutes. Next, add the heavy 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. While the saucepan is off the heat, continue to stir it until it cools down to room temperature.

Now, transfer the caramel syrup into a jar until you want to use it.

Tips to make the best sugar free salted caramel syrup

  • This recipe is designed to be a caramel syrup, not a sauce. Because of this, you want to remove it before it becomes too thick, as it continues to thicken as it is cooling down. If you’d prefer a thicker caramel, try keto caramel or vegan caramel
  • 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 accidentally burn the mixture. 
  • 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. 

Storing and freezing caramel coffee syrup

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. 
  • To thaw: Let the caramel syrup thaw completely to room temperature.

    1. 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

    2. 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 .
