1tbspinstant coffeeit's faster if you use an instant coffee of the self-foaming / espresso type. I have to reiterate that it doesn't work with ground coffee.

1-3tbspcocoa powder
To serve
Glass of milk with ice or hot milk in a cup
Instructions
For the whipped coffee layer
Place everything in a bowl and whisk vigorously. It also helps if you have an electric mixer, it takes 10-15min by hand. Stop when it's fluffy.
Add the cocoa powder a tablespoon at a time until you like the intensity. I personally used 1 tbsp. Whisk it together.
To serve
Serve the whipped coffee over a glass with iced milk or a cup of hot milk and enjoy :)
