In a medium mixing bowl, combine the dry ingredients together (coffee, sugar, and flavor powder). Whisk the dry ingredients until evenly incorporated.
Add the water to the dry mix. Using the electric hand mixer on a low setting, whisk the ingredients together. After 1 minute, increase the speed of the mixer to a medium setting.
Whisk for another 3-4 minutes until stiff peaks form. Set aside.
Fill your glass with your milk of choice and ice leaving at least 1 inch of room. Using a spoon, top your drink with the whipped coffee mixture. Sip and enjoy!
