Need more sugar-free syrups? Try my sugar-free caramel syrup, keto maple syrup, and keto simple syrup next. It’s important to have a few staples in your sugar-free diet. And yes, I consider chocolate syrup a staple. I used to swear by Hershey’s sugar-free chocolate syrup, but now that I know how to make it from scratch, I’ll never go back.
Why I love this recipe
Made with 4 wholesome ingredients. And zero artificial flavor, sugar, thickeners, or sodium benzoate (whatever that is). Versatile. Drizzle it over keto ice cream, keto pancakes, or a keto milkshake. There are no wrong answers! The perfect texture. It’s thick and smooth yet pourable like any good chocolate syrup should be. Have it whenever you need it. Once it’s made, you can store your chocolate syrup for up to two weeks–not that it’s ever lasted that long in my house!
Ingredients needed
Sweetener. I prefer allulose because it doesn’t crystalize and won’t leave the sauce gritty. If you don’t have either, use sucralose or keto powdered sugar. The only sweetener I don’t recommend is stevia, which I tested and found to be quite bitter. Cocoa powder. I used sifted unsweetened cocoa powder. Avoid using raw cocoa powder as it can be VERY bitter. Salt. A pinch to balance the sweetness. Water. Use tap or chilled water. I also tested this with unsweetened almond milk, and I actually preferred the consistency of it with water. Vanilla extract. Essential for the overall flavor.

In a small bowl, whisk together the cocoa powder, sweetener, and salt. Add the mixture to a saucepan with the water and whisk to combine. Step 2- Boil. Place the pan over medium heat. Once it’s boiling, reduce to low heat and simmer for 1-2 minutes, stirring regularly. Step 3- Chill. Remove the syrup from the heat and whisk in the vanilla. Let it cool completely, then transfer it to a shallow jar and refrigerate for an hour to thicken.
Arman’s recipe tips
If your chocolate sauce is too thin, don’t worry. It’ll continue to thicken as it cools down. That said, if you want it EXTRA thick, add 1 teaspoon of xanthan gum. Enhance the chocolate flavor. Use dark or black cocoa powder and add a pinch more sweetener. Use a good quality cocoa powder. Trust me, it makes all the difference!
Storage instructions
To store: Homemade chocolate syrup is not shelf-stable. It should be stored in an airtight container in the refrigerator for up to two weeks. Let it sit at room temperature for 15 minutes before using. To freeze: Place the leftover syrup in a shallow container and freeze it for up to six months.
