This simple drink that's taking over the internet is a must try. You can make it so many different ways and there's no wrong method.
Combine the granulated instant coffee, sugar, and boiling water in a medium to large mixing bowl and whip by hand with a whisk or with a hand mixer. By hand should take 6 to 8 minutes and with hand mixer it should only take 4 or 5. Beat until light and fluffy.
For iced coffee, pour milk into a glass and add some ice and extra flavor (cinnamon, vanilla....) if you like. Spoon the whipped coffee over the top, stir together, and enjoy! (For hot coffee, simply warm the milk first.)
You can use any or no sugar here (coconut, brown, cane....). If using stevia or no sugar the whip will not hold very long but it will still work. The other sugars will last much longer.
