Keto Sugar Free Caramel Sauce Recipe

  • Total Time: 12 minutes
  • Yield: 6 servings 1x


This keto caramel sauce recipe has rich, buttery caramel flavor with a hint of vanilla. It has just 1g net carbs per serving and takes less than 15 minutes to make; you’ll want to drizzle it on everything!


  • 1/4 cup unsalted butter
  • 2 tablespoons granulated erythritol
  • 3/4 cup heavy whipping cream
  • 1/2 teaspoon blackstrap molasses
  • 1/2 teaspoon pure vanilla extract
  • 1/4 teaspoon cream of tartar
  • 1/8 teaspoon stevia glycerite
  • 1/16 teaspoon salt


  1. Add the butter and granulated erythritol to a medium saucepan over medium heat. Bring to a boil and then cook until it turns light brown, about 3 to 4 minutes, swirling the saucepan occasionally.
  2. Add the heavy whipping cream, molasses, vanilla, cream of tartar, stevia glycerite, and salt. Bring to a boil, and then cook until the sauce is thickened slightly (it should coat the back of a wooden spoon), about 3 to 5 minutes. (Don’t overcook it, because it’ll thicken more as it cools and it will set into a thick caramel paste if refrigerated overnight.)
  3. Serve hot.


  • Net Carbs: 1g per serving (each serving is 2 tablespoons)
  • If you can't find stevia glycerite, you can omit it and use 1/4 teaspoon liquid stevia extract instead.
  • Cool leftover Caramel Sauce to room temperature, and then put it in an airtight container and store it in the fridge for up to 2 weeks. To reheat caramel sauce, put it in a microwave-safe container and heat it in the microwave in 15-second increments (stirring between each increment), or in a double boiler. Note that it will thicken after it’s refrigerated, but it will thin out after reheating.
  • Don’t skip the cream of tartar because it helps prevent crystallization so your caramel sauce is silky smooth.
  • UPDATE: I now prefer to use allulose instead of erythritol in this recipe. Allulose caramelizes like sugar, but doesn't have a cooling effect and doesn't crystallize. To use allulose instead of erythritol, simply omit the erythritol and add 4 tablespoons granulated or powdered allulose (yes, 4 tablespoons is correct).
