Ok I’ve been on a complete chocolate kick of late. This recipe is going to be 1 in a series of 3 that are all pretty close. In fact I realized that the next 2 that I’ll post are basically the same recipe, the only difference is one has Kahlua in it. Now with all three of these it’s all about the cocoa. Use good cocoa, not that Hershey stuff!

This one is my favorite of the 3 that I’ll be posting. It’s super moist and the frosting, which has Bailey’s in it, is super flavorful. The original recipe had the frosting as a buttercream, which I am not a fan of. So I cut it down by adding a little cream cheese and reducing the sugar dramatically. I mean really, do you need 6 cups of powdered sugar in your frosting? Enjoy!


Guinness Chocolate Cake with Irish Cream Frosting


  • 1 3/4 cups all-purpose flour
  • 2 cups sugar
  • 3/4 cup Dutch processed cocoa powder (darker the better)
  • 2 tsp baking soda
  • 1/2 tsp baking powder
  • 1 tsp kosher salt
  • 3/4 cup sour cream of plain full fat yogurt (I used sour cream)
  • 1/2 cup vegetable oil
  • 3 large eggs, at room temp
  • 1 tsp real vanilla extract
  • 1 cup Guinness beer


  • 4 sticks unsalted butter, at room temp*
  • 8 oz cream cheese, at room temp
  • 2 cups powdered sugar
  • 6 tbsp. Bailey’s Irish cream liqueur


Preheat your oven to 350°. Spray two 8″ cake rounds, or one 9″x13″ cake pan, with non-stick cooking spray. Line with parchment paper and spray again.

Sift together, in a large bowl, the flour, sugar, cocoa, baking soda & powder, and salt. In a large measuring cup, beat the eggs and sour cream until smooth. Add in the vegetable oil, vanilla and bear.

Add the liquid to the sifted dry ingredients and fold together with a spatula until just combined. Like brownies, you don’t want to over mix it or you’ll have a chewy cake. Pour into your cake pan or pans and bake for 40 to 45 minutes; or until a toothpick comes out of the center clean. Allow to cool completely.

In a stand mixer, with the whisk attachment, beat the butter and cream cheese until smooth. *Note: buttercream based frostings can be a real bitch. You want the butter soft, and I do mean soft! So while I put “at room temp” the warmer the better. But DO NOT MICROWAVE IT! Doing so has a tendency to make the butter melt in pockets and that won’t work for your frosting. Once it’s smooth Alternate the Bailey’s with the powdered sugar until it’s all incorporated and smooth. Then frost your cake.
