Put the Heavy Cream (1/2 cup) in either a bowl and whip with a whisk (electric or otherwise) or you can put it in the blender. Whip until soft peaks and then add Granulated Sugar (1/2 teaspoon).
Take your Orange (1) and peel off a couple long strips of zest. Lightly "burn" them with a lighter. This will help the oils come out and will flavor the coffee later.
Pour the Brandy (0.5 fluid ounce), Grand Marnier (0.5 fluid ounce), and Kahlua (0.5 fluid ounce) in a mug.
Add the Coffee (5 fluid ounce).
Stir with the Orange Peels.
Spoon some whipped cream on top and enjoy right away!
