Guinness Cake

  • 1 3/4 cup flour, all purpose
  • 2 cups sugar
  • 3/4 cup cocoa powder, unsweetened
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon kosher salt
  • 1 cup Guinness Stout
  • 1 cup buttermilk
  • 2 eggs
  • 1/2 cup vegetable oil
  • 1 teaspoon vanilla extract

Irish Cream Frosting

  • 16 ounces cream cheese, room temperature
  • 1/4 cup butter, room temperature
  • 2 cups powdered sugar
  • 1/2 cup Irish Cream liquor ie Baileys


  • Preheat the oven to 350 degrees.
  • Whisk together all of the dry cake ingredients together in a large mixing bowl.
  • Add the Guinness, buttermilk, eggs, oil, and vanilla to the dry ingredients.
  • Beat at a medium-high speed for two minutes. The batter will appear very thin.
  • Use a 4-ounce ice cream scoop or a 1/4 measuring cup to scoop batter into paper-lined muffin tins.
  • Bake for 18-22 minutes, just until a toothpick inserted in the center comes out clean.
  • Cool completely before frosting.

Irish Cream Cream Cheese Frosting

  • Cream together the room temperature cream cheese and butter until light and fluffy.
  • Add the Irish Cream and powdered sugar and beat until smooth and creamy.


For a stiffer frosting more suitable for intricate decorating, use an additional 1/2 to 1 cup of powdered sugar until desired consistency is reached.
For additional baking pan options, flour and grease and bake. Cool in the pan for 15 minutes.
To make a 9x13" cake, bake for 35-40 minutes.
To make two 9" cakes, bake for 28-35 minutes.
For a 12 bundt or tube pan, 50-55 minutes. Less detailed bundt pans are a better choice from a possibly sticking perspective.
