Step 1

In a mixing bowl, combine the instant coffee and sugar with 2 tablespoons of hot water, then beat together using an electric whisk. The mixture will start to turn shiny and smooth as you whisk. Continue whisking until the mixture becomes thick and frothy and a pale toffee colour, then keep whisking until stiff peaks form – the peaks will hold their shape when you lift out the beaters.

Step 2

Fill your glass with milk, then top up with ice. Spoon the whipped coffee on top, then stir into the milk. Enjoy straight away.
