First, combine the instant coffee, sugar, and hot water and mix until it becomes stiff. Takes about 3 minutes. Stop when soft peaks form.
Serve your brownie (I suggest warming it up), then add a scoop of ice cream on top. Add a scoop of your whipped coffee over it. Next pour about a tablespoon of Baileys liquor and finally, sprinkle cocoa powder on top to dress it. Enjoy!
