Mix the maida, sugar, baking powder, chocolate powder, and cocoa powder and strain through a fine sieve. Mix the milk powder and essence and add the milk; prepare a mixture and beat it with a hand mixer. Take a greased oven dish and pour the mixture; bake in the oven for 30 minutes.
After the mixture is done and cooled down, make small balls and place in a tray.
Grate the chocolate slab and dip the chocolate balls in the grated chocolate and serve. It's a yummy and mouth-watering chocolate dish.
