One Bowl Chocolate Guinness Cake

A light, moist chocolate cake with Guinness Stout that adds rich, malty flavor. This is a great cake for a weeknight because it can be made in just a few minutes in one bowl.
This cake is great with the frosting recipe provided, but can also be served with just a dusting of powdered sugar.

Equipment

  • 8-inch Cake Pan

Ingredients

Chocolate Guinness Cake

  • 1 1/4 cup (150g) All-Purpose Flour
  • 1 cup(200g) Sugar, granulated
  • 3/4 cup Unsweetened Cocoa Powder (not Dutch-process cocoa)
  • 1 tsp Baking Soda
  • 1/2 tsp Salt
  • 1/4 cup Vegetable Oil
  • 1 1/4 cup(10oz) Guinness Stout (can or bottle)
  • 1 tsp Pure Vanilla Extract

Vanilla Frosting (with optional Bailey’s Irish Cream)

  • 3 oz Cream Cheese, softened
  • 1/3 cup Powdered Sugar
  • 1 cup Heavy / Whipping Cream, chilled
  • 2 oz Bailey’s Irish cream (optional)

Instructions

For cake:

  • Heat oven to 350 degrees F.
  • Spray an 8-inch round cake pan with nonstick cooking spray. (Note: If you have a pan that tends to stick, line the bottom of the pan with a round of parchemnt paper that you've cut to fit inside the pan.)
  • In a large mixing bowl whisk together flour, sugar, cocoa powder, baking soda, and salt.
  • Add oil, Guinness, and vanilla extract all at once and stir just until everything is combined and no dry spots remain.
  • Pour batter into prepared cake pan.
  • Bake until the cake is set in the middle, 27 to 30 minutes. (Note: In a thicker pan made of glass or ceramic, the cake may take up to an extra 5 minutes to cook all the way through.)
  • Allow cake to cool completely.

For frosting:

  • Combine cream cheese and powdered sugar in the bowl of a standing mixer. Turn the mixer on medium and beat until evenly combined.
  • Turn the mixer down to medium-low speed and slowly pour the heavy cream and then Bailey’s (if using) down the side of the bowl with the mixer running.
  • When all of the cream has been added, increase speed to medium-high until stiff peaks form. If the frosting is too thick to spread with a spatula, add more heavy cream 1 tablespoon at a time.
  • At this point, frosting can be refrigerated up to 1 day.
  • Spread frosting on cake just before serving (after it has cooled completely).

Notes

Frosting / Topping - If you prefer the frosting to have less of an alcohol flavor, just skip the Bailey’s Irish Cream. If you’re short on time, you can skip the frosting altogether and just top the cake with a dusting of powdered sugar.
