Add the instant coffee crystals and the sugar to a bowl.
Add the boiling water and whisk like your life depends on it using either a fork, a whisk or an electric hand mixer. Whip until the mixture becomes really smooth and then KEEP WHIPPING until the mixture holds shape on it own.
Top a cup of cold milk (ice optional) with the whipped mixture. Take your Instagram pics now, because the mixture will settle in and blend with the milk. Enjoy!
*INSTANT coffee, not ground coffee
**Really make sure that your water is very hot, if not boiling. It needs to be able to dissolve the sugar and coffee crystals.
