Happy St. Patrick's Day! Drinking a good old-fashioned Irish Coffee is a great way to celebrate today (or any day, Irish Coffee is delicious and makes a great nightcap all year long). This super yummy traditional coffee drink is surprisingly easy to make; you really only need 4 ingredients: a cup of coffee, a tablespoon of sugar, a shot of whisky, and a dollop of cream. Putting it all together is a breeze too (under 5 minutes; ten if you make your own whipped topping).
