Developing the Best Keto Sugar-Free Caramel

If you watched my Instagram Stories the last few days, you know that I tried for three days straight to get the perfect keto sugar-free caramel recipe for you. My first two tries were complete failures, and I guess it was due to high temperatures. Next, I tried to brown the butter first. The results were satisfying. The sauce is delicious, but it has burn butter pieces, and I wanted a completely smooth caramel without sugar. 

Finally, after I adjusted to measurements, temperature, and cooking time while testing different sweeteners, I made the best homemade sugar-free caramel sauce.

Perfect Caramel Sauce has to be:

  • Luscious, Smooth, and Creamy
  • Rich & Buttery 
  • Pourable
  • Foolproof
  • Sweet enough but not overpowering

Ingredients in Keto Caramel Sauce 

This easy recipe needs only 3 ingredients, whole ingredients in this easy recipe, and it takes just 15 minutes to make.

ingredients for keto low carb caramel sauce
  • Heavy cream – a key ingredient in any caramel sauce recipe.
  • Sweetener – I use this Brown Sugar Replacement with Allulose. It’s the best sweetener that replicates granulated brown sugar when making caramel without sugar. You can also erythritol-based sweeteners, brown sugar substitutes such as Sukrin Gold.
  • Butter – I recommend using unsalted butter.
  • Optional: Vanilla and sea salt to make keto salted caramel – while most keto caramel recipes require vanilla extract, I think it tastes incredible without it. 

How to Make Easy 3 Ingredients Sugar-Free Caramel Sauce

Making keto low carb caramel sauce is similar to traditional caramel sauce:

  1. Melt the butter and incorporate the sweetener.
  2. After the sweetener completely dissolves, add heavy cream.
  3. Reduce the heat and simmer for about 10 minutes or until the sauce is thick enough.

How to Store Keto Caramel?

It’s best to store the low carb caramel sauce in the refrigerator for up to 2-3 weeks. As the caramel cools down, it solidifies, so you need to reheat it in the microwave or on the stove to make it pourable again. You can leave the caramel sauce at room temperature for a few hours to make it liquidy again without risking the oil separation. 

Keep in mind that when you reheat this sauce, the temperature should be super low—using a higher temperature will lead to the oils separating.

Keto Caramel sauce tips and questions:

How to Fix Your Sugar-Free Caramel Sauce?

To fix it (in case of oil separation), remove the caramel sauce from the heat, transfer to a larger bowl, and allow to cool down slightly. Whisk vigorously to reincorporate the oil and make a smooth keto caramel sauce. Then, transfer the caramel into a jar or container. 

What’s the best sweetener to use?

  • Allulose and xylitol are the best. The resulting keto caramel is luscious and sticky, with no thickener required. Plus, both sweeteners keep your caramel ultra smooth, and I didn’t experience any crystallization whatsoever with either.
  • Swerve Brown or any brown sweetener replacement. I discovered that using erythritol crystalizes the sauce as it cools down, but you can reheat it. 

Can you freeze caramel sauce? 

Yes, that’s an option. When ready to serve, thaw it in the fridge overnight before serving. 

How many carbs are in a serving?

Even that this sauce looks and tastes so indulgent, it’s made only with keto-friendly ingredients. A tablespoon of this keto caramel sauce has only 1g bet carbs!
