In a medium size bowl or the bowl of a stand mixer combine the instant coffee, sugar, and hot water.
Whisk until light colored and fluffy.
Pour milk in a mug and dollop the whipped coffee on top.
Stir to combine and enjoy!
Notes
Try replacing 1 tablespoon of the coffee with 1 tablespoon of cocoa powder for a dalgona mocha or adding a teaspoon of vanilla extract for a vanilla dalgona latte.
