Brew 1 cup of hot coffee and pour it into a heatproof glass mug.
Add 1–2 tablespoons of salted caramel sauce into the coffee. Stir until it melts in completely.
Add 1–1.5 ounces of Irish whiskey and 0.5 ounce of coffee liqueur. Stir again.
If you want it sweeter, toss in 1 teaspoon of brown sugar and stir until it disappears.
Top with a big spoonful of whipped cream. I try to let it float right on the surface for that classic look.
Drizzle a little extra salted caramel sauce over the cream.
Sprinkle on a pinch of sea salt flakes. Shaved chocolate or cocoa powder is a nice touch, but totally optional.
Serve it warm, right away—don’t wait around.
Nothing too tricky here, but really whisking in the caramel makes the drink extra smooth.
