In a coffee mug, put instant coffee powder and sugar. Add 1 tsp. water and mix.

With a spoon, start beating the mix vigorously. You have to incorpotate as much air as you can. That will give you the whipped frothy coffee-sugar mix. The more you beat, the mix will become pale in colour. Make sure your mix is whipped and creamy enough.

Heat a cup of milk and pour it over the whipped coffe-sugar paste. Stir. Sprinkle cocoa powder and serve immediately.
