Take 1 cup of milk in a bowl and add cornflour and cocoa powder to it. Whisk to make a slurry and until no lumps remain. Keep it aside.
In a saucepan set on medium heat, add the remaining 1 cup of milk 🥛 along with sugar and coffee powder. Mix till sugar and coffee completely dissolves.
Add the cornflour slurry and keep on whisking on low-medium heat till is starts to thicken.
Once the mixture bubbles up and becomes thick, take it off the heat and pour in a 6X6 mould.
Set it in the refrigerator for 1 hr or till it sets completely. It should have a jiggly texture but not break.
Demould and cut equal cubes of the pudding and coat it in the drinking chocolate powder.
