Recipe By:Rebecca Lamb
"A friend of mine suggested that I try Guinness(R) cupcakes as my next baking adventure, and they came out amazing."

Ingredients

  • Cupcakes:
  • 1 (12 fluid ounce) can or bottle Irish stout beer (such as Guinness(R))
  • 1/2 cup milk
  • 1/2 cup vegetable oil
  • 1 tablespoon vanilla extract
  • 3 large eggs
  • 3/4 cup sour cream
  • 2 1/2 cups all-purpose flour
  • 2 cups white sugar
  • 3/4 cup unsweetened cocoa powder
  • 1 1/2 teaspoons baking soda
  • Frosting:
  • 1/4 cup unsweetened cocoa powder, or more to taste
  • 1/4 cup Irish stout beer (such as Guinness(R))
  • 1/2 cup butter, softened
  • 1/2 cup cream cheese, softened
  • 2 1/2 cups sifted confectioners' sugar, or more as needed

Directions

  1. Preheat the oven to 350 degrees F (175 degrees C). Grease two 12-cup muffin tins or line cups with paper liners.
  2. Whisk stout beer, milk, vegetable oil, and vanilla extract together in a bowl until evenly blended. Beat in eggs 1 at a time, beating well after each addition. Mix in sour cream. Whisk together flour, sugar, cocoa powder, and baking soda in a separate bowl. Gradually mix the flour mixture ingredients into the beer mixture.
  3. Spoon cupcake batter into the prepared muffin cups, filling each 3/4 full.
  4. Bake in the preheated oven until cupcakes are risen and set in the middle but still soft and tender, about 25 minutes. Cool in the tins, then transfer to a wire rack to cool completely, about 1 hour.
  5. Whisk cocoa powder and stout beer together in a bowl. Beat in butter and cream cheese using an electric mixer until well combined. Gradually beat in confectioners' sugar, 1 cup at a time, until frosting has desired sweetness. Spread or pipe frosting onto cooked cupcakes.
