Need a low-carb sugar free chocolate syrup recipe to use for making keto chocolate milk and ice cream sundaes? There's no need to buy one. It’s super easy to make your own!
Lately, I’ve been craving a lot of chocolate. In particular, a chocolaty alternative to almond milk. Then it dawned on me that I just need to make a sugar-free chocolate sauce to add to a cold glass of milk.
When I first went low-carb, I used to buy sugar free chocolate syrup. The brand I used was Walden Farms zero carb chocolate syrup. These days, there are better sugarless options like Lakanto sugar-free chocolate syrup. and Hershey's sugar free syrup.
Eventually, I stopped buying commercially prepared products that contain artificial sweeteners. Unfortunately, Walden Farms uses sucralose as the added sweetener in their syrup which isn't natural like monk fruit extract.
Hershey's sugar free syrup also adds sucralose as well as artificial flavor and some other questionable ingredients like sodium acid sulfate, potassium sorbate, acesulfame potassium, zinc sulfate, and sodium benzoate. That's why I came up with this sugar-free recipe!
You only need a few ingredients to get the iconic flavor of Hershey without those artificial ingredients. Here's what you need to make your own homemade chocolate syrup.
Regular unsweetened cocoa powder is what I use to provide a natural flavor. If you need a more rich and genuine chocolate flavor, you can melt in a little low-carb dark chocolate or stevia sweetened chocolate.
If you don't want to follow my dark chocolate recipe, you can always buy it from Good Chocolate instead.
Although you only need one keto-friendly sweetener, I often use concentrated vanilla stevia liquid and mix it with a powdered erythritol or allulose sweetener. What you use to sweeten the syrup is really up to your own personal taste and preference. If you don't use a vanilla liquid sweetener, you should add in a half teaspoon or so of vanilla extract.
Just a pinch of salt goes a long way in enhancing the chocolate flavor so don't leave it out!

Recipe Quick Tips
- Add a thickener. You can thicken up the syrup by adding in a little xanthan gum or guar gum. However, cooking the mixture with some melted chocolate will thicken it without having to add any low-carb thickener.
- Check the carb count on the cocoa. Some unsweetened cocoa powders have less carbs than others. Be sure to check the labels before buying to make sure you choose one with the lowest carb count.
- Use a whisk. I find that a whisk helps blend the cocoa powder into the liquid best. I also like to use a mix of sweeteners.
You should be able to whip this chocolate syrup up within 10 or 15 minutes. Once you gather all your ingredients it’s just dumping it into a saucepan, whisking it up, and cooking it up a bit.
1. Combine the ingredients
Whisk together all of the ingredients in a small pot until they are well combined.
2. Cook it
Bring the mixture to a boil over medium heat. Then reduce the heat and simmer on low for about five to ten minutes.
Once the mixture has thickened, remove it from the heat and stir in the vanilla liquid sweetener or a little vanilla extract.
The delicious taste of chocolate syrup can be used in so many ways! Add a chocolate drizzle to your midday coffee for a little sweetness and classic mocha flavor.
It blends well with unsweetened almond milk or coconut milk for a keto chocolate milk or hot cocoa. It's also a great way to add a little chocolate flavor to all your favorite drinks.
It's great for adding extra goodness to keto treats. Just pour a chocolate drizzle of the syrup over the top of your favorite desserts.
I also use this sugar free chocolate sauce in my no bake banana split cake cheesecake.
Common Recipe FAQs
Before getting to the full recipe and instructions, I wanted to answer a few of the questions I often get asked about the recipe.
Not all sugarless syrups are keto-friendly. Stay away from ones with sugar alcohols and hard to pronounce ingredients. Since Hershey's syrup uses preservatives and artificial ingredients, it's not the best choice for a keto diet.
My homemade syrup has just one gram of net carb for a one tablespoon serving. It's almost impossible to to find a true chocolate syrup without carbs because cocoa and chocolate are not carb-free.
If you don't want to make your own syrup, my top choice is Lakanto chocolate syrup because it has zero net carbs and is made with quality ingredients like erythritol and monk fruit extract.
Yes! Pure stevia has zero carbs and no calories! You can read more about it in my post about this common question: Is stevia keto friendly?
