Guinness Chocolate Cake

by Megan on March 17, 2011

I frosted this cake on my lunch break.

I also managed to pump gas, get a few groceries, bring Elliot out twice for backyard-prancing, make a disaster of the kitchen, take photos, give Elliot a strawberry, make two willy-nilly veggie burritos, and then zoom back to work.

Last night, I ate cake before dinner, appetizer-style. Eating dessert first is where it’s at, especially on St. Patrick’s Day Eve. I think it should be a tradition.

Now, about this cake. It’s stout, dark and handsome; it’s dense and chocolatey.

The truth is, I love this cake. I may as well marry it.

What I’m trying to say with my lunch story, messy kitchen, and beer cake is:

Guinness Chocolate Cake
Recipe adapted from the Barrington Brewery, via Smitten Kitchen


  • 1 cup Guinness, or any stout beer
  • 1 cup (2 sticks) unsalted butter
  • 3/4 cup unsweetened cocoa powder, preferably Dutch-process
  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 1 1/2 t baking soda
  • 3/4 t salt
  • 2 large eggs
  • 2/3 cup sour cream


  1. Preheat the oven to 350°F. Spray a bundt pan very well; getting in all the nooks and crannies. Set aside.
  2. Bring the Guinness and butter to a simmer in a heavy saucepan over medium heat. When the butter is melted, add the cocoa powder and whisk until mixture is smooth. Cool slightly.
  3. Whisk the flour, sugar, baking soda, and salt in a medium bowl to blend. In a large bowl using an electric mixer, beat the eggs and sour cream. Add Guinness-chocolate mixture to egg mixture and beat just to combine. Add flour mixture and beat briefly on slow speed. Using a rubber spatula, fold batter until completely combined. Pour batter into prepared bundt pan.
  4. Bake cake until tester inserted in the center comes out clean, about 45-55 minutes (check after 35 minutes). Transfer cake to rack; cool completely in the pan, then turn cake out onto a cake plate and frost.

Starry fluffy frosting.

Fluffy Cream Cheese Topping
Recipe adapted from Nigella Lawson


  • 1 1/4 cups + 1/2 cup confectioners’ sugar
  • 8 oz. cream cheese, at room temperature
  • 1/2 cup heavy cream


  1. Beat together the confectioners’ sugar and cream cheese until smooth, add heavy cream, and mix until smooth. Spread over the top of the cake. If planning to pipe the frosting, add an additional 1/2 cup powdered sugar and then pipe it onto the cake. Just so it resembles a frothy pint of Guinness!

We go together like Guinness and chocolate.

I am lucky enough to have HAD a piece of it!!! Delish..a question…can you drive after you eat a piece…?

Yum, yum, YUM!!! I had planned to try making a dessert with Guinness in it for St. Patrick’s Day this year but felt so crummy with my cold that I skipped it. I might have to make this just for fun, though. It looks SO darn good! And that is one gorgeous picture of that Guinness bottle 🙂


Megan (megabite) March 20, 2011 at 6:57 am

Colds ruin everything. I hear ya. I think this could be an anytime of year cake. I mean, it’s not like we only like beer on St. Patrick’s day, right?

That Guinness bottle is a supermodel. haha

The photos at the end of the post are so cute! You are quite the multi-tasker. When I used to have lunch breaks, I would spend them watching DVDs that I brought into my workplace or I would go shopping – you are much more productive than I!

Thank Sydney!

This lunch was a rare one. Normally I just sit on the couch eating lunch. 🙂

Now Guiness is something I’ve got plenty of over here in the uk!!! I’m going to an thing next month which is “bake around the world” and I’ve been racking my brain thinking of something to take that’s a bit different. This might have to be it as a belated St Paddy’s cake!


Megan (megabite) April 3, 2011 at 9:11 am

Awesome, Lucy! You totally should make this. 🙂 That party sounds so fun!
