Step 1

Whisk together boiling water, instant coffee, and sugar with an electric mixer at medium speed until the mixture is thick and forms stiff peaks, about 2 to 3 minutes. Scrape the bottom and sides of the bowl occasionally while whipping.

Step 2

Pour the milk into a tall glass, leaving 2 inches of room on top. Spoon the Dalgona froth on top of the milk. Stir vigorously and enjoy!
