This Keto Caramel Sauce tastes just like the classic version, with a silky texture that stays smooth even after chilling. The recipe requires only four ingredients and a few minutes to make! You won't need any weird thickeners or stabilizers, either-just pure, caramel bliss.

Unlike some recipes for keto caramel sauce, this one is a breeze!
Caramel has a reputation for being somewhat tricky, but the secret to success for making a silky-smooth and buttery caramel at home is all in the sweetener of choice.
the best sweetener for keto caramel sauce
Allulose is a rare natural sweetener that browns and caramelizes beautifully-unlike erythritol, which can crystallize and become crunchy.
It also has no aftertaste and gives caramel that same glossy, thick texture and golden brown color that you would get from sugar.
I love using a granulated monkfruit and allulose blend because of its clean flavor and smooth texture.
While other low-carb sweeteners can leave you with a gritty consistency or strange aftertaste, a blend of monk fruit and allulose creates that rich, buttery flavor of true caramel that we're going for.
While allulose behaves similarly to sugar when heated, it caramelizes at a much lower temperature than sugar, so make sure to keep an eye on it.
The sweet spot for keto caramel is 230-240°F (110-115°C)-this is where it turns golden and rich without burning or seizing. It's also the heating point that will keep your caramel from turning tacky or too thick once cooled.

why you'll love this recipe
The perfect keto caramel sauce does exist, and it's so simple to make in a matter of minutes.
This syrupy, saucy caramel is perfect for drizzling over desserts, coffee, and any of your favorite sugar free treats that could use an extra bit of goodness.
- Real caramel flavor: Made by actually caramelizing the monkfruit/allulose blend, not just mixing it with cream. Allulose behaves similarly to real sugar because you can brown it and get that wonderful toasted sugar flavor.
- Perfectly smooth: No crystallization or graininess, ever. Allulose/monkfruit sweetener blends dissolve wonderfully and won't recrystallize once chilled.
- Low-carb & sugar-free: Only about 1 g net carbs per tablespoon which makes this a healthy, sugar free caramel syrup that is low carb diet and keto diet friendly.
- Versatile: Drizzle it over your favorite low carb ice cream, on top of coffee or other drinks, or use it for layering in keto desserts!
the ingredients
Here's a look at the basic ingredients you'll need but be sure to check out the printable recipe card for all of the details.
- Monk fruit sweetener with allulose: Granulated, preferably golden sweetener, for a little bit deeper toasted sugar flavor.
- Butter: Salted, grass-fed butter adds balance and depth which is why I recommend it. However, unsalted butter works just as well too.
- Heavy cream: For a rich taste, creaminess, and that delicious mouthfeel that is classically caramel.
- Vanilla extract: Adds a sweet, warm flavor.
- Pinch of salt: Optional, but an extra little bit of salt will transform this low carb caramel sauce into a delicious salted caramel.

how to make keto caramel sauce
Here's a look at the process but check out the full recipe card below for all of the details.
- Melt the butter and sweetener: Melt the butter in a medium saucepan set on the stovetop over medium heat. Stir in the sweetener and continue heating until it has dissolved and the mixture is syrupy. It will turn a golden brown color.
- Pour in the cream: Slowly add the cream while stirring. It might seize up briefly; keep whisking over low heat until smooth again. Stir constantly until the mixture reaches 230-240°F (it should stick slightly to a wooden spoon).
- Finish with flavor. Remove from heat, stir in vanilla and a pinch of salt. Let it cool before using-it thickens as it cools!


recipe tips
- Make sure you're using a granulated monk fruit sweetener with allulose OR plain granulated allulose. Regular monk fruit sweetener blends made with erythritol are not ideal because erythritol is prone to crystallizing once it is chilled. If using granulated allulose, increase to 1-¼ cups since plain allulose is less sweet.If you want a thicker caramel for dipping, I recommend using an instant-read thermometer or candy thermometer to get the ideal temperature. Allulose and sweetener blends made with allulose have a lower burning point than sugar. If cooked too long, the sweetener can burn and/or you may end up with a caramel that will cool to the consistency of a chewy candy.
- Stir frequently for an even caramelization.
- If you prefer chewy caramel that's the consistency of apple dipping caramel, cook to 260-270°F.
- Add a few flakes of sea salt for a gourmet salted caramel version.
substitutions
- Whipping cream: Substitute with canned, full-fat coconut cream.
- Sweetener: Substitute with granulated allulose, increasing the amount to 1-¼ cups.
storage
Store the caramel sauce in a glass jar in the fridge for up to three weeks. A mason jar or another type of storage jar with lids are perfect for these!
When you're ready to use it, you can spoon it out (if the consistency is thin enough) or gently reheat the caramel in the microwave (10-15 seconds) or in a warm water bath until smooth and pourable again.
equipment recommendations
- Glass canisters or storage jars with lids
- Silicone spatula
- Medium saucepan with a heavy bottom
- Instant read thermometer or digital candy thermometer

4-Ingredient Keto Caramel Sauce (Sugar Free)
This keto caramel sauce is rich, buttery, and glossy—just like traditional caramel but with zero added sugar and only 1 net carb per serving! It's delicious on desserts, coffees, fruit, or anything that could use a little drizzle of rich caramel.
Ingredients
- ½ cup salted, grass-fed butter
- 1 cup granulated monkfruit sweetener with allulose (not erythritol)
- ½ cup heavy cream or coconut cream
- 1 teaspoon vanilla extract
- Pinch of fine sea salt (increase to ½-¾ teaspoon or add to taste for a salted caramel)
Instructions
- In a medium saucepan set over medium heat, melt the butter. Stir in the granulated monk fruit/allulose sweetener and continue heating until the sweetener has dissolved and the mixture is syrupy, about 5 minutes.
- In a small stream, pour in the cream while whisking the mixture vigorously (it may bubble up which is normal).
- Continue stirring and heating for another few minutes, or just until the mixture has slightly thickened. For a syrupy sauce, heat only a few minutes (the caramel should not get hotter than 240°F).
- Remove from heat and stir in the vanilla extract and salt. Let the caramel cool for 15 minutes, then pour into a heat-proof, glass storage container. Use or store in the fridge. The caramel will thicken more as it cools.
Notes
- Make sure you’re using a granulated monk fruit sweetener with allulose OR plain granulated allulose. Regular monk fruit sweetener blends made with erythritol are not ideal because erythritol is prone to crystallizing once it has cooled.
- If using granulated allulose instead of a monkfruit/allulose blend, increase the amount to 1-¼ cups since plain allulose is less sweet.
- If you want a thicker caramel for dipping, heat it to 265-270° measured with an instant read or candy thermometer. Keep an eye on it-- allulose (and blends containing allulose) have a lower burn point than sugar.
- Nutritional calculation subtracts 9.6 grams of allulose from the total carbohydrates which leaves 0.4 grams net carbs per serving.
