Ingredients

  • 1 ½ sticks unsalted butter, room temperature
  • 1 cup granulated sugar
  • 3 large eggs
  • 1 tsp vanilla extract
  • ¾ tsp peppermint extract
  • ¾ cups all-purpose flour
  • ¾ cup unsweetened cocoa powder
  • ½ tsp baking soda
  • ¼ tsp salt
  • ½ cup whole milk
  • cup chocolate chips

Baileys Frosting

  • 1 ½ sticks unsalted butter, room temperature
  • 3 ½ cups confectioners' sugar
  • Pinch of salt
  • ¼ cup Baileys Irish Cream

Instructions

  • Preheat oven to 350 degrees and line a cupcake tin with 12 papers.
  • In the bowl of a stand mixer or in a large bowl with a hand mixer, cream together butter and sugar on medium-high speed until light and fluffy, about 3 minutes.
  • Add eggs in one at a time, mixing well after each addition. Mix in vanilla and mint extracts.
  • In a separate medium bowl, whisk together flour, cocoa powder, baking soda, and salt.
  • With mixer on low speed, mix in dry ingredients in 2 additions, alternating with milk. Mix in each addition until just incorporated. Gently fold in chocolate chips.
  • Fill cupcake liners about ¾ of the way with batter. Bake cupcakes for 18-20 minutes, until toothpick inserted into center comes out clean.
  • Let cupcakes cool in tin for 5 minutes before moving to wire racks to cool completely.
  • Frost cupcakes with Bailey's frosting. I used a pastry bag and Wilton 1A pastry tip for mine. Top with additional chocolate chips, if desired.

Baileys Frosting

  • In the bowl of a mixer or in a large bowl with a hand mixer, mix butter on medium speed until it’s nice and fluffy. Add confectioners’ sugar one cup at a time and beat until well-combined. Mix in salt.
  • Add the Baileys and beat until combined. If frosting is too thin, add more confectioners' sugar a couple tablespoons at a time.
