Instructions

1. Add heavy/whipping cream to a medium-sized mason jar or sealed container. Shake for about 45 seconds and check consistency. You want it slightly thickened but still slowly pourable. If it gets too thick, thin out with a little extra cream and stir.
2. Combine coffee, sugar, and Irish whiskey in a glass coffee mug. Stir until sugar dissolves.
3. Top with a collar float of lightly whipped cream by gently pouring over a spoon at the coffee’s surface. Serve immediately.
