Today’s cake is the result of both my being too lazy to go to the store and the good fortune of having some Guinness in the refrigerator. It’s a great cake – moist, but not too rich to handle a good frosting. The original recipe is adapted from a cake served at Barrington Brewery in Barrington Hill, MA. You can find it on Epicurious. The Epicurious recipe makes one huge cake, so I cut it in half and ended up with just enough batter for a 2 layer 8 inch round cake.
I didn’t have any whipped cream, so for the frosting I used a recipe from Cooking With Amy. Since the cake is made with Dutch cocoa, I decided to add some contrast and use natural style cocoa in the frosting.
Chocolate Guinness Layer Cake
- 1 cup Guinness Stout
- 2 sticks butter 8 oz, unsalted (230 grams)
- ¾ cup Dutch process unsweetened cocoa powder or Hershey’s Dark
- 2 cups all purpose flour 260 grams
- 2 cups granulated sugar 390 grams
- 1 ½ teaspoons baking soda
- ¾ teaspoon salt
- 2 large eggs
- ⅔ cup sour cream
- 8 oz butter softened – I used salted because it was all I had. If using unsalted, you’ll probably need to add a few pinches of salt to icing.
- ⅔ cups unsweetened cocoa – sifted for this I used natural
- 2 ½ to 3 cups confectioner's sugar measured and sifted
- 2 tablespoons Guinness Stout
- 1 teaspoon vanilla
- Preheat oven to 350 degrees F. Spray two 8-inch round cake pans with flour-added cooking spray.
- Place butter in a saucepan and turn heat to medium. When butter is almost completely melted, add stout and cook over medium until mixture starts to simmer. Reduce heat slightly, add cocoa powder and stir or whisk until smooth. Remove from heat.
- In a large bowl, thoroughly whisk together flour, sugar, baking soda and salt.
- In a mixing bowl, using an electric mixer, beat eggs until thick and lemon colored – beat for a full five minutes. Add the sour cream and beat until combined. Add the stout mixture to the egg mixture and stir just until mixed. Add the flour mixture and stir until well mixed.
- Divide the batter equally between the two pans. Bake for 28-32 minutes or until cakes test done (toothpick inserted comes out clean). Cool in pans for 10 minutes, then flip and let cool on a cooling rack.
- To make the frosting, stir together softened butter, cocoa and 2 cups of the sugar. Add Guinness and vanilla and stir again. Using high speed of electric mixer (I use the whipping attachment on my stand mixer), beat icing for a minute. Add the rest of the sugar, adding just until you think it’s the right consistency. Beat for a good 3-5 minutes, scraping side of bowl often, until light and fluffy. Ice the cake.
