Add the instant coffee, sugar, and hot water to a small bowl. (I just use hot water from the faucet)
Use a hand mixer with a whisk attachment or a hand mixer with just one beater attached to whip the coffee mixture until it is thick and creamy.
Fill a glass with a good amount of ice, and milk. (Use more or less milk depending on how strong you want the drink)
Add the whipped coffee mixture to the glass with the milk and stir to enjoy!
