The moist, delicate Irish Coffee Cupcakes are flavored with espresso and brown sugar and topped with billowy whipped-cream frosting spiked with whiskey. A dusting of espresso powder makes a festive finish. If you don't have two muffin tins, bake these cupcakes in batches. Ingredients For the Cupcakes 2 cups all-purpose flour 1 teaspoon baking powder ¼ teaspoon baking soda ¼ teaspoon salt ½ cup boiling water 2 tablespoons instant-espresso powder ¼ cup whole milk 1 stick unsalted butter, room temperature ½ cup granulated sugar ½ cup packed light-brown sugar 2 large eggs For the Frosting 1 cup heavy cream 1 tablespoon confectioners' sugar 1 tablespoon whiskey Instant-espresso powder, for dusting Directions Preheat oven to 350 degrees. Make the cupcakes: Whisk together flour, baking powder, baking soda, and salt. Pour water over espresso powder; let cool. Combine espresso with milk. Beat butter and granulated and brown sugars with a mixer on medium speed until pale and fluffy, about 3 minutes. Add eggs, 1 at a time, beating well after each addition. Beat in flour mixture in 3 additions, alternating with espresso-milk mixture, beginning and ending with flour (batter may look broken). Fill 15 cups (of two 12-cup muffin tins) three-quarters full. Bake until a toothpick inserted into the centers comes out clean, 20 to 22 minutes. Let cool; turn out cupcakes from tins. Make the frosting: Whisk together cream and confectioners' sugar until medium peaks form. Add whiskey; whisk until slightly stiff peaks form. Top each cupcake with 2 tablespoons frosting; dust with espresso powder. Rate it Print
