Sugar Free Keto Chocolate Sauce. A quick, no-fuss recipe WITHOUT cream, butter or thickeners. 0.3g carbs per serving.
You only need a small saucepan, two ingredients plus water, and a few minutes.
This silky-smooth, lightly sweet sauce is perfect over berries, whipped cream, ice cream or any dessert that needs a rich chocolate finish.
It’s velvety, not overly sweet, and far healthier than store-bought syrups.
How to Make Sugar Free Keto Chocolate Sauce
Use a small heavy-base saucepan to reduce the risk of burning. Any unsweetened cocoa powder will work; choose the lowest-carb option you can find. A high-quality 100% cocoa powder gives the best flavour, but common unsweetened cocoa is an acceptable substitute.
For sweetness, allulose yields the smoothest texture without crystallisation. If you only have pure allulose, you may need a little more to reach your preferred sweetness. Powdered erythritol can be used in a pinch, but it tends to crystallise and can make the sauce grainy.
A pinch of salt and a small amount of vanilla extract improve the flavour but are optional. You can also experiment with a few drops of orange or mint extract, or add a pinch of sea salt, cracked black pepper, or chilli flakes for a creative twist.

Method: Combine the dry ingredients with the water in the saucepan and stir continuously over medium heat until the powders dissolve. Once the mixture begins to bubble, reduce to a gentle simmer and cook for 2–4 minutes, stirring frequently and scraping the base so nothing sticks or burns. Remove from heat when the sauce coats your spatula, stir in vanilla if using, then transfer to a jar and cool to room temperature.

Store the sauce at room temperature. It will thicken over time; loosen it by stirring in a few drops of water or warming very briefly in the microwave.
Enjoy!
Sugar Free Keto Chocolate Sauce
Equipment
- Saucepan (small, heavy-base, ~1.5 quart)
- Flexible spatula or mini spatula
- Container or jars for storing
Ingredients
- 25 g 100% cocoa powder (or similar)
- 50 g allulose (or allulose blend)
- 100 g water
- 1 pinch fine salt (optional)
- 1/8 tsp vanilla extract (optional)
Instructions
- Put the cocoa powder, allulose, water and salt (if using) into a small heavy-base saucepan and stir to combine.
- Place the saucepan on the hob over medium-high heat.
- Stir continuously with a flexible spatula until the powders dissolve and the mixture comes to a bubble.
- Reduce to a gentle simmer and cook 2–4 minutes, stirring occasionally and scraping the base to prevent sticking. Two minutes yields a pourable sauce; four minutes gives a thicker, denser sauce.
- Remove from heat when the liquid coats your spatula. Stir in vanilla if using, then transfer to a jar and let cool to room temperature.
- Store at room temperature. If the sauce thickens too much, loosen with a few drops of water or warm briefly.
Notes
Simmering time controls texture: 2 minutes = very pourable; 4 minutes = more viscous. The sauce will continue to thicken as it cools and during storage.
If the sauce becomes too dense, stir in a few drops of cold water or heat for 2–3 seconds to loosen it.
Avoid erythritol if possible — it tends to crystallise and can make the sauce grainy. If you must use it, use powdered erythritol.
