How to make easy keto caramel
- To a saucepan over medium-low heat, add butter and allulose. The butter will melt and will start to bubble, resembling a low boil (do not move on to the next step before the mixture is really bubbling and looks like it’s at a low boil).
- At this point, start a timer to simmer the mixture for 3 minutes, stirring a few times with a rubber spatula. You may need to reduce stovetop heat to low to avoid caramel burning. After 3 minutes have passed, pour in heavy cream (you may need to remove the pan from heat to avoid it boiling over), then add SunButter, and, optionally, salt. Whisk ingredients together and then reduce stovetop heat to the lowest temperature.
- Cook mixture until it begins to thicken, which may take anywhere from 7-15 minutes, depending on the room temperature of your kitchen, stirring a few times. Watch the mixture carefully to avoid burning.
- Meanwhile, while the caramel is simmering, to a large mixing bowl, add ice cubes and water to create an ice bath. When the caramel has finished simmering, transfer the saucepan to sit inside the bowl for about 1-2 minutes, depending on the thickness of your saucepan, to stop the cooking process. (If you do this for too long, the caramel may split. If that happens, transfer the pan back to the stovetop over low heat to warm up again, stirring continuously. If you do this, don’t return the pan back to the ice bath.)
- Set the saucepan aside and allow it to sit at room temperature to thicken, which may take anywhere from 10-20 minutes. It should resemble the thick and sticky caramel that you are familiar with (see photo below for reference, if needed).

Ingredient substitutions
- Unsalted Butter: Vegan butter or ghee should work here, though I cannot say for sure since I have not personally tested these. I would not use coconut oil in place of butter for this recipe.
- No Sugar Added SunButter: If you do not have peanut or tree nut allergies, unsweetened peanut butter or unsweetened almond butter can be substituted at a 1:1 ratio.
- Heavy Whipping Cream: Half-and-half will work in place of heavy whipping cream here.
Keep in mind any changes you make to this recipe will modify the total net carbs.
Easy keto caramel syrup with allulose FAQs
Is there another sweetener I can use besides allulose?
No. Unlike other sweeteners, it is the only option to make this caramel. Monk fruit, erythritol, Swerve, etc., all crystallize, whereas allulose remains smooth to yield a perfect caramel.
My caramel sauce split. Is there a way to fix it?
Yes, you can usually repair caramel by reducing the heat or stirring in a few teaspoons of cold water if it has split. If neither of these remedies works, the caramel may very well be ruined, and you’ll, unfortunately, have to start over.
Should I refrigerate keto caramel?
Homemade caramel should be stored in an airtight container or jar. In the refrigerator, the caramel will stay fresh for up to 2 months. To soften, let the caramel sit at room temperature for about 30 minutes before using.
Can leftover keto caramel be frozen?
Yes, when stored in a jar or airtight container, keto caramel will keep for up to 6 months in the freezer. Let it thaw completely in the refrigerator before using.
Can keto caramel be reheated?
Yes! Caramel may be reheated. I recommend heating it in the microwave or on the stovetop. If you’re using a microwave, heat in 20-second increments and stir between each heating to prevent burning. When reheating on the stovetop, proceed slowly and stir frequently until it reaches your desired temperature.
