Heat water till about boiling temperature. It will whip better the hotter it is.
With a whisk attachment on an immersion blender, stand mixer, or just a hand whisk, beat together the instant coffee, sugar, and water until it is light and fluffy. With an electric mixer this will take about 1 minute. With a hand mixer, expect about 10 minutes.
Add milk and ice to a glass. Scoop the whipped coffee over the top.
Stir together and enjoy!
You can enjoy this with a ratio of 1:1:1 water, coffee, sugar, but you can also increase the coffee slightly and/or reduce the sugar some and it'll still taste great!You can add a 1/4 tsp of vanilla or a dash of cinnamon for an additional great flavor.
