Sugar Free Chocolate Syrup

When it comes to keto baking staples, my favorite recipes to make are condensed milk, maple syrup, and this sugar free chocolate syrup. 

Growing up, one of my favorite desserts was ice cream sundaes. There was something special about the combination of ice cream, chocolate syrup, and sometimes some crushed nuts. Granted, it wasn’t really the ice cream itself that stood out, but the rich and smooth chocolate sauce poured all over it.

In my household, my mom would make her own chocolate syrup. We never had any of the bottled stuff and because of that, it tasted so much better. As it wasn’t the healthiest of treats, it wasn’t something we enjoyed regularly but when we did, it would essentially be a chocolate syrup with a side of ice cream.

Is chocolate syrup keto? 

Since going keto, I’ve been using a few kinds of syrups, include Hershey’s and Torani syrups. Unfortunately, these two brands tend to be a little too expensive, and not necessarily keto friendly. Luckily, making your own homemade chocolate syrup is actually very easy to do, and even easier to make low carb! 

I’ve been meaning to share a sugar free chocolate syrup recipe for quite some time. It needs just 3 main ingredients to make, and is perfect to add to all your favorite keto desserts! 

No sugar and no dairy are needed, but you’d never tell. The texture is thick, smooth, and perfectly pourable. It’s sweet and full of chocolate, with no artificial aftertaste whatsoever! 

The beauty of this syrup is just how versatile it is- Add it to smoothies, top your pancakes with them or even use them as a dipping sauce for strawberries!

How do you make a keto chocolate syrup?

The Ingredients

  • Granulated sweetener of choice– Allulose is preferred, as it doesn’t crystalize and won’t leave the sauce gritty. If you don’t have allulose, you can use keto powdered sugar
  • Cocoa powder– Unsweetened cocoa powder. Be sure to sift it well prior, to ensure there are no clumps throughout. 
  • Salt– A pinch to balance out all the sweetness. 
  • Water– Tap water or chilled water. Do not use boiling or hot water. 
  • Vanilla extract– A must, to give a lovely and light vanilla note. 

The Instructions

Start by adding your sweetener, cocoa powder, and salt into a mixing bowl and whisk together until combined. Next, add them to a small saucepan, add the water, and place it over medium heat. Once it begins to boil, reduce the heat to low. Let it simmer for 1-2 minutes, stirring regularly. 

Now, remove the saucepan from the heat. Let it cool to room temperature, then whisk in the vanilla extract. Transfer the chocolate syrup into a shallow container or jar and refrigerate for at least an hour, to thicken.

Tips to make the best sugar free chocolate sauce

  • Don’t fret if the syrup seems very thin- it continues to thicken as it cools down. 
  • For a richer chocolate flavor, you can use dark or black cocoa powder. Again, make sure it is of the unsweetened kind. 
  • If you use a glass jar or bottle, be sure to sterilize them carefully prior to adding the syrup to them. 

Storing and freezing keto chocolate sauce

  • To store: Chocolate sauce can be stored in the refrigerator, in a sealed jar or container. It will keep well for up to 2 weeks. Remove the sauce from the refrigerator 15 minutes before using it. 
  • To freeze: Place leftover chocolate sauce in a shallow container and store it in the freezer for up to 6 months.

    Best homemade chocolate syrup ever! Way better than any store bought! I love being able to make it sugar free with allulose. Thank you so very much for sharing this recipe!

  2. I have made this but did not have allulose at the time. I have some liquid allulose and need to know how much of that to use instead of the powder. If you could let me know I would very much appreciate it. Thanks Vicky

    Thick and delicious. I cut the allulose and increased the cocoa slightly as I found it a little too sweet. I used 1/2 natural and 1/2 Dutch cocoa for a deep rich flavor.

    I must remind myself that restraint is still needed. While it has way fewer calories than chocolate sauce made with sugar, it’s not calorie free.

    This tastes almost exactly like Hersheys Syrup! Don’t judge it while it’s warm on the stove. Chilling makes all the difference.

    This syrup is such a tasty addition to sugar free ice cream! And when I want it more like hot fudge I just add a teaspoon or so of ground chia seeds as it cooks. Thickens it up nicely. Thanks so much for elevating my sugar-free diet!

    Made this this afternoon. It’s delicious!!! I was craving hot cocoa, and this really hit the spot! Thank you, for this recipe, it saved me from caving in, and buying the Hershey’s syrup, and I don’t like the “sugar free” alternative, which you need a chemistry degree, to decipher!

    I made this for my mocha coffee. I was looking for a sugar free option to using store bought cocoa mix. I’m staying away from corn syrups and other additives as much as I can. I only added an extra cup of water so it’s not too thick for measuring and stirring into my decaf. 🙃

  8. oh my god!! This was so good.. I just bought a bag of allulose and this was teh first recipe I tried. So so so so worth teh extra cost … the sauce was AMAZING! I made the mistake of dipping my finger in to try some and could barely resist drinking the lot! Thank you so much… allulose definitely makes a HUGE difference as I have tried making sauces with monkfruit, sucrose, stevia, erythritol, but this is by far the best. So excited to try out on more recipes 🙂

  9. This seems simple. Was looking into how to make sf simple syrup and find this one as well. Vanilla only balances the chocolate flavor so it’s not noticeable. Only if you add it to plain simple syrups will you notice it.

    Making this right now for the 3rd time in a month! My midwife recommended that I have chocolate milk on hand as a post-birth re-energizing drink (fats, protein, sugar) for my home birth and I wanted to have a version healthier than what I could find at the store. I can’t remember the last time I had chocolate milk (probably at least 15 years ago), so this was such a treat!! I was on a liquid chocolate milk diet for at least 3 days. I also used it to make mocha lattes by just adding warmed milk and espresso. So good!!

  11. Just thinking about the possibility of using brewed or espresso coffee instead of water. Would it intensify the chocolaty flavor or spoil it? Feedback welcome. Cheers & Stay Safe Y’all!

    1. Hi Manny! I haven’t tried- I don’t see why not- I’d do half water and half coffee, just so it won’t have any possible coffee flavor 🙂
