Ingredients

Scale
  • 1 ½ cups (190g) all-purpose flour, sifted
  • 1 cup (200g) granulated sugar
  • 2 tbsp (15g) unsweetened cocoa powder
  • 1 ½ tsp baking powder
  • ½ tsp baking soda
  • ¼ tsp salt
  • ½ cup (115g) unsalted butter, softened
  • 2 large eggs, room temperature
  • ½ cup (120ml) strong brewed espresso, cooled
  • 2 tbsp (30ml) Irish whiskey
  • 1 tsp vanilla extract
  • ½ cup (120ml) buttermilk (or milk + 1 tsp lemon juice)
  • 8 oz (225g) cream cheese, softened
  • ½ cup (115g) unsalted butter, softened
  • 3 cups (360g) powdered sugar, sifted
  • 2 tbsp (30ml) Irish whiskey
  • 1 tsp vanilla extract
  • 12 tbsp (15-30ml) heavy cream

Instructions

  1. Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper cupcake liners.
  2. In a medium bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
  3. In a large bowl, beat softened butter and granulated sugar until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, then stir in vanilla extract.
  5. In a small bowl, combine cooled espresso and Irish whiskey.
  6. Add dry ingredients to butter mixture in three parts, alternating with buttermilk and espresso-whiskey mixture, starting and ending with dry ingredients. Mix gently after each addition.
  7. Spoon batter evenly into cupcake liners, filling about ¾ full.
  8. Bake for 18-22 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  9. Cool cupcakes in the tin for 5 minutes, then transfer to a cooling rack to cool completely.
  10. For frosting, beat cream cheese and butter until smooth and creamy.
  11. Gradually add powdered sugar on low speed to avoid sugar clouds.
  12. Add whiskey and vanilla extract, then beat until fluffy.
  13. If frosting is too thick, add heavy cream one tablespoon at a time until desired consistency is reached.
  14. Frost cooled cupcakes using a spatula or piping bag. Optionally, garnish with grated dark chocolate or cocoa powder.

Notes

Use room temperature eggs and butter for best mixing results. Sift cocoa powder and flour to prevent clumps. Avoid overmixing after adding dry ingredients to keep cupcakes tender. Use freshly brewed espresso for best flavor. Frost cupcakes only when completely cooled to prevent melting frosting. For stronger whiskey flavor, brush cupcakes with extra whiskey after baking but avoid soaking.
