Whip the cream until thick, but not stiff and set aside.
If you want a rich flavor without added sweetness, you can make your own simple syrup using brown sugar or demerara sugar instead of white or pre-made simple syrups.
In a warmed toddy mug, Irish coffee glass or sturdy wine glass, combine the whiskey, simple syrup and coffee.
Stir to combine, and gently spoon between 1/2-inch and an inch of cream atop the coffee mixture, to taste.
