Preheat the oven at 180°C.
In a bowl sieve all the dry ingredients (i.e. flour, baking powder, sugar, milk powder, cocoa)
In a separate bowl, whisk hot water and butter till combined.
Now, slowly pour the wet ingredients into the dry mix, while whisking.
Grease 6 medium-sized ramekins with butter and dust them with some cocoa powder.
Portion ⅔ of the batter equally in all the ramekins, add around 10gm of chocolate in the centre of each ramekin and cover it with the batter.
Bake it for 12 min or till the edges and top are crisp.
Dust a little cocoa powder and serve.
