Chocolate Guinness Layer Cake

by on January 15, 2008 · 29 comments

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 cocoa in the frosting. 

Chocolate Stout Layer Cake

Chocolate Guinness Layer Cake

1 cup Guinness Stout
2 sticks butter (8 oz)
3/4 cup Dutch process unsweetened cocoa powder or Hershey’s Dark
2 cups all purpose flour
2 cups granulated sugar
1 1/2 teaspoons baking soda
3/4 teaspoons salt
2 large eggs
2/3 cup sour cream

Preheat oven to 350 degrees F. Spray two 8-inch round cake pans with flour-added cooking spray (flour-added Pam worked well, as usual).

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 mixing bowl, thoroughly whisk together flour, sugar, baking soda and salt.

In a second 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 among 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.

Chocolate Frosting

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.
2/3 cups unsweetened cocoa – sifted (for this I used natural)
2 1/2 to 3 cups confectioner’s sugar, measured and sifted
2 tablespoons Guinness Stout
1 teaspoon vanilla

Stir together softened butter, cocoa and 2 cups of the sugar. Add Guinness and vanilla and stir again. Using high speed of electrix 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.

Ahhhhhhh! Guinness! That looks fantastic! When I was pregnant with AK, her nickname was Guinness (we didn’t know the sex of the baby). I found out I was pregnant right after we got back from Ireland, so ….. Guinness it was! My grandma told me that all the pints I had in Ireland (before I knew I was with child) would just make the baby stronger. ;)

Guinness cake – that’s something I can get behind!

Anna January 15, 2008 at 1:35 pm

Good story! You’ll have to show me your Ireland pictures one day.

I’ll save you some cake.

Amy January 15, 2008 at 1:44 pm

I made this for Gary’s birthday one year. I agree, it’s great. I put the extra batter into cupcakes.

Christy January 15, 2008 at 2:48 pm

The close-up picture looks like you could stick your finger right in the frosting and steal a taste! I have never heard of Guinness in my life. Any chocolate cake is good but I especially love Texas Sheet Cake.

Chelsea January 15, 2008 at 6:29 pm

Hmm, I’m not a big Guinness fan, but my hubby is. His b-day is in April, and I’ve been wondering about cakes/brownies w/Guinness. Maybe I’ll give it a try!

Shannon January 15, 2008 at 7:41 pm

That is an amazing picture!

Anna January 15, 2008 at 8:04 pm

Hi Amy!! Good idea about the extra batter. For our purposes, halving worked out really well.

Christy, it’s funny that you should mention Texas Sheet Cake because I almost made that. However, I wanted to make something new and since we had the Guinness, wel….

Chelsea, this one’s tried and true. If you do a Google search, you’ll find some other variations.

Thanks, Shannon. I’m having so much fun playing with lights and angles now that I have a better camera.

Your cake is beautiful, Anna! And I’m sure that frosting will be useful for a number of other cakes.
Tks for sharing!

Mary M January 16, 2008 at 7:34 am

MMMMMMMMMMMMMMMMMMMmmmmchocolate AND Guinness- my two favorite food groups!

T. Martin January 16, 2008 at 8:54 am

I tried a Guinness cake several years ago and was less than pleased with the results (tasted bitter to me) but your picture (amazing how a good camera can produce amazing images) is encouragement to try this cake again. I have to say I love Guinness Brownies (recipe can be found on

Julie O'Hara January 16, 2008 at 10:55 am

Great recipe! And the photo looks soooo enticing. I have a Guinness cupcake with espresso frosting recipe that I really like, but I would try this one next time I want to do a big chocolate cake.

Amy January 16, 2008 at 11:51 am

Yum!!! I LOVE Guinness and the picture is amazing, the cake looks so moist and delicious!

Joe January 16, 2008 at 1:53 pm

*sigh* I really miss being able to have chocolate. This cake looks fantastic! Great idea using Dutch in the cake and natural cocoa in the icing.

rebecca January 16, 2008 at 9:32 pm

wow. this might be a good one to bake for a coworker’s farewell party next week! thanks!

Bunny January 19, 2008 at 5:44 pm

I’ve just put this cake in the oven and can’t wait until it comes out. Do I read the recipe correctly on the amount of butter in the frosting? Is that 2 sticks? I wondered if that amount might make the frosting too thin.

Anna January 19, 2008 at 5:49 pm

Hello Bunny,

Yes, 2 stick (8 oz) is correct. I didn’t find it too thin or too buttery. However, frosting is a personal thing, so adjust the sugar and liquid to your liking.

Bunny January 19, 2008 at 6:30 pm

Thanks for the quick reply, Anna. The cake is cooling as I type this. Can’t wait to try it! BTW – I happened upon your blog last week and have added it to my GoogleReader blog feed. Thanks for the awesome recipes!

Bunny January 19, 2008 at 9:06 pm

One last comment – this cake is awesome! We’re not Guinness drinkers here and I ended up going to The Fresh Market to find it and had to buy a 6 pack. It was so worth it. Thanks for posting it, Anna.

Stef January 24, 2008 at 9:24 am

This looks great! I made something similar but used a double chocolate stout instead of Guinness. I’ve been thinking about trying it with other beers.

Meg January 26, 2008 at 4:37 pm

Anna, I am making this cake for a party tomorrow. The cake is out of the oven (batter was delicious!) and I am trying to figure out how to store it until tomorrow. Should I frost and assemble later this evening, then refrigerate the whole cake, or should I just wrap the layers, make the frosting tonight, refrigerate that, assemble and frost the cake tomorrow? Or something else entirely? I don’t bake a lot of cakes so I don’t know what’s best. Thanks!

Anna January 26, 2008 at 5:02 pm

Hi Meg,

I’d frost it this evening, cover the cake with something, and refrigerate it until tomorrow. It’s such a moist cake that it will stay fresh for a few days and the refrigerator won’t dry it out if it’s covered in frosting.

Meg January 26, 2008 at 8:29 pm

Thanks for the quick reply, Anna. I am just back from dinner out. Tired but going to rally and frost tonight! I’ll let you know how it turns out!

Meg January 27, 2008 at 6:58 pm

The cake was a huge hit! Comments included, “this is the best homemade chocolate cake I have ever had!”
While I want to be good at making cakes, I always seem to run into problems (they come out dry, fall apart while trying to assemble, get too crumbly while frosting), and therefore don’t have a lot of confidence when it comes to baking cakes. Now that I know I can make a good cake (this one), maybe my confidence will grow and I will try more!
Thanks for sharing this winner!

Anna January 27, 2008 at 7:48 pm

Hi Meg,

That’s great news! I’ve been baking for years and am still sensitive to comments made about whatever it is I’ve served. It’s really great when a recipe works out perfectly and everyone notices how good it is. I’m glad you liked this one. I did too. It really stood out amongst all other chocolate cakes.

Jackie March 15, 2008 at 11:52 am

When I got married in January we had this cake as our wedding cake. BEST chocolate cake ever!!

dgeevanson May 24, 2008 at 6:18 pm

Ok don’t throw eggs at me but – is there anything that you could sub for the beer and still get the same moist results? This cake looks and sounds fantastic. Thanks

Anna May 24, 2008 at 9:27 pm

Jackie, that is cool. Did people know it had stout in it?

Darla, I think it would be great with coffee instead of beer. You could also try it with coke or Dr. Pepper. It would be a little sweeter, but not much…the cake’s not overly sweet to begin with.

Lucy October 16, 2008 at 11:58 pm

Anna, this is my favorite chocolate cake -I’ve made it several times and absolutely love it. I’m making it again today for a party but I’m out of Hershey’s Dark, can I use natural unsweetened (in the cake)? Thanks!

Anna October 17, 2008 at 6:22 am

Hi Lucy,

I think it would work. The results will be a little different, but it should still be a good cake.
