Add the brown sugar to the glass or mug. Pour a small amount of hot coffee over the sugar and stir until fully dissolved.
Pour in the Irish whiskey and stir gently to combine with the sugared coffee.
Fill the glass almost to the top with freshly brewed hot coffee, leaving enough space for the whipped cream.
Carefully layer the freshly whipped cream over the back of a spoon onto the surface of the coffee. The cream should float on top.
Notes
You can make the coffee with any method you prefer.While you can add any whiskey to this drink, it’s not an Irish coffee without Irish whiskey such as Jameson, Bushmills, Redbreast, Tullamore Dew, and more.I love a clear coffee mug for this cocktail as it allows you to see the division between the black coffee and the white whipped cream. But any coffee mug or glass that can hold hot liquid (so a handle is nice) can work.
