Sterilize a glass jar and let it dry.

Measure cocoa powder, Palm jaggery, and water. Keep it ready. Add Palm jaggery/Jaggery/sugar to the saucepan and add water to it.

Now in the same saucepan, add cocoa powder and pinch of salt to the melted jaggery/Palm jaggery/sugar.

Mix well with a whisk continuously until it starts to boil. Once it started boiling, let it cook in a medium-low flame until it becomes slightly thick. It may take 3 minutes.

Boil it until it becomes quite dark, thick, and reached honey-like consistency. Switch off the flame once done and add vanilla syrup. Mix well and let it cool down. Once it is cooled down completely, store it in a sterilized glass jar.
