In a sauce pan add Coco Powder and sugar and mix properly

Then add water to it and mix again without any lumps

Then keep the sauce pan on gas and switch on. Let the sugar melt in

After that let the syrup cook and thicken a bit. It will take 4 to 5 mins

Now switch off the gas and let it cool down.

Though the syrup is still watery, it will thicken when cool down.

Store it in an air-tight container in fridge. It will be stored for a month.
