Moist chocolate cupcakes are baked with Guinness Stout for an extra rich chocolatey flavor. Topped with Bailey's Irish Cream Frosting, these cupcakes will be the next hit at your party!


Units Scale
  • 1- 11.2oz Bottle of Guinness
  • 94 grams (3/4 Cup) All-Purpose/ Plain Flour
  • 45 grams (1/2 Cup) Dutch-process Cocoa Powder
  • 1/2 Teaspoon Baking Soda
  • 1/2 Teaspoon Salt
  • 100 grams (1/2 Cup) Granulated Sugar
  • 50 grams (1/4 Cup) Light Brown Sugar
  • 2 Large Eggs, at room temperature
  • 2 Teaspoons Pure Vanilla Extract
  • 4oz (1/2 Cup) Sour Cream, at room temperature
  • 2.7oz (1/3 Cup) Vegetable Oil
  • 1/2-1 Batch of Frosting- Baileys Swiss Merinuge Buttercream or Chocolate Cream Cheese Frosting, or Coffee Frosting


  1. In a medium pot over low-medium heat simmer the Guinness beer for 10-15 minutes to reduce the mixture by roughly half, 5oz. Set aside.
  2. Preheat oven to 350F/180C and line a muffin tray with cupcake liners.
  3. In a large bowl whisk together the flour, cocoa powder, baking soda, salt, and sugars.
  4. In a medium bowl whisk together the eggs, vanilla, sour cream and oil.
  5. Gently whisk the liquid into the dry ingreients until just combined, then pour in the hot Guinness. This batter will be very liquidy.
  6. Fill each cupcake liner 1/2-2/3rds full and bake for 14-18 minutes, or until when gently touched in the center the cake bounces back or a toothpick inserted in comes out clean with no wet batter. Let cool on a wire rack until cooled to room temperature.
  7. Frost with desired frosting and enjoy.
