In the bowl of an electric mixer add cold whipping cream and beat until very soft peaks have formed. The whipped cream should be thickened but still light and spoonable. Set aside once ready.

Set out 2 traditional Irish coffee mugs (or 2 coffee cups) and add 1 tablespoon dark brown sugar into each cup.

Pour 5 ounces hot coffee into each glass and stir to help dissolve the brown sugar.

Pour in 1-1/2 ounce Irish whiskey into each glass.

Carefully spoon whipped cream onto the top of the coffee. You should have a 1-2 inch thick topping of whipped cream.
