  • ½ cup (113g) unsalted butter, softened

  • 3 ½ cups (420g) powdered sugar, sifted
  • 2 tbsp bourbon (for frosting, adjust to taste)
  • 12 tbsp heavy cream (to adjust frosting consistency)
  • 1 tsp fresh mint leaves, finely minced (optional, for frosting)
  • Pinch of salt (for frosting)

Instructions

  1. Preheat oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
  2. In a medium bowl, whisk together flour, sugar, baking powder, and salt.
  3. In a large bowl, cream ½ cup softened butter with an electric mixer on medium speed until smooth and pale, about 2-3 minutes.
  4. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract and 2 tbsp bourbon.
  5. Alternately add dry ingredients and milk, starting and ending with dry ingredients. Mix on low speed just until combined.
  6. Fold in finely chopped fresh mint leaves.
  7. Divide batter evenly among liners, filling each about two-thirds 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 pan for 5 minutes, then transfer to a wire rack to cool completely.
  10. To make frosting: Beat 1 cup softened butter on medium speed until creamy, about 2 minutes.
  11. Gradually add powdered sugar, mixing well between additions.
  12. Add 2 tbsp bourbon, pinch of salt, and 1 tablespoon heavy cream. Beat on high for 3 minutes until light and fluffy. Adjust consistency with more cream or powdered sugar if needed.
  13. Fold in minced fresh mint (optional).
  14. Pipe or spread frosting generously over cooled cupcakes.
  15. Garnish with a small mint leaf or a light dusting of powdered sugar if desired.
