Original recipe makes 1 9-inch 2-layer cake with frosting Change Servings
  • PREP

    35 mins
  • COOK

    30 mins

    1 hr 45 mins


  1. Preheat oven to 350 degrees F (175 degrees C). Line 2 9-inch cake pans with parchment paper, and spray with cooking spray.
  2. Pour the beer into a saucepan, add the butter, and bring to a simmer over medium-low heat. Remove the pan from the heat, and whisk in the cocoa powder until the mixture is smooth. Allow the mixture to cool. In a bowl, beat the eggs and sour cream together until smooth with an electric mixer, and stir in the stout mixture to make a smooth, thick liquid.
  3. In a large bowl, mix together the flour, sugar, baking soda, and salt. Pour the stout mixture into the flour mixture, and gently combine with a spatula. Pour the batter into the prepared pans.
  4. Bake in the preheated oven until the cakes are set and a toothpick inserted into the center of a cake comes out clean, about 30 minutes. Remove and let cool in pans for 5 minutes before inverting the cakes onto wire racks to finish cooling.
  5. Mix together the confectioners' sugar, butter, and Irish cream liqueur until the mixture forms a smooth and spreadable frosting (add more sugar or liqueur as needed to create the desired consistency). Spread half the frosting on top of each cake.
  6. Place the chopped chocolate into a heatproof bowl. Bring cream to almost boiling in a small saucepan, and pour over the chocolate. Stir in the butter, and stir the mixture until the chocolate melts and the mixture is very smooth. Allow to cool until the mixture is pourable but not thin or overly runny, 10 to 15 minutes. Stack a cake gently on top of the other, frosting sides uppermost, and carefully drizzle the chocolate mixture over the cake, allowing decorative drips to run down the sides.

I made this recipe into cupcakes and it was great. I filled each cupcake with the Bailey's buttercream and topped each with the chocolate ganache. They were a big hit!

I thought this was a fairly easy recipe to follow but I skipped the chocolate drizzle part to save time. I'm not sure why but my cake was a bit dry which puzzled me....I will make this again and give it another shot because what's not to like about chocolate and Guinness and Bailey's? LOL

Who'd ever guess that a recipe for chocolate cake that uses Guinness would turn out to be the best darned chocolate cake I've ever tasted?? Who says you can't teach an old dog new tricks? From here on, I'm going to keep a bottle of Guinness in the fridge, and I detest beer of any kind! This is now my go-to chocolate cake recipe. And that's no faint praise, coming from a pastry chef of many years! The stout really complements and rounds out the flavor of the chocolate, plus lends a lovely reddish hue. You never taste it, but it's there, lending its incomparable support to the star of the show (chocolate.) This cake is blow-your-socks-off good, incomparably moist with a very fine, tender crumb. I spiked the ganache with a Tb of Jameson's Irish Whiskey. I cut the centers out of each cupcake (mmmm...chocolate cake scraps to eat!) and filled the holes with the ganache, opting to use it as a filling rather than as a drizzle. I doubled the amount of Irish Cream in the frosting, as well. Served to ooohs, aaahs, moans, groans, swoons, and general paroxysms of pleasure.

I served this at a St. Patty's Day party and it was a HUGE hit!! Instead of using 2 9-inch cake pans, I used 2 8-9 inch square glass pans and it came out just right after 30 mins. Also, instead of stacking the cakes, I frosted them separately and severed them as 2 cakes. It went further and the pieces were big enough. (Both cakes feed 20-24 people). If you are going to make 2 cakes, make extra frosting. I doubled the frosting recipes and had left overs. I added more Bailey's to the white frosting since the recipe was a little too thick to spread. At the end of the evening, everyone requested a copy of the recipe. THAT'S how I know it was good.

OMG! This is the best chocolate cake i have ever made or tasted. and it is easy. i modified the frosting to sub 3/4 cup cocoa for 1 cup of the powdered sugar. this made a great chocolate baileys buttercream. when making as a whole cake, i skipped the ganache (the last part of the ingredients list) delicious without it!

Good Flavor, Easy Preparation. The frosting needed to be spread a little thin to cover 2 layers and sides. But there was plenty of chocolate drizzle to have easily covered both layers. We preferred the texture and flavor of a room temperature slice vs. a refrigerated slice that had been served. Next time we plan to make more of the frosting, as there will definitely be many more next times. Don't forget to stir the flour/sugar mixture before adding the stout mix as it helps to prevent flour lumps in your batter. Happy Baking : )

Delicious! I did bake this in a 9"x13" baking pan and left it in the pan. Cooled it, then frosted and ganached it. Turned out perfect and went to my son's business for St. Patrick's Day. Everyone loved it and wanted the recipe.

This is a great recipe; very easy to make and delicious! I followed the recipe to the letter and it came out perfectly - DO BE SURE TO LINE YOUR BAKING PANS WITH PARCHMENT PAPER! In my enthusiasm, I forgot to line mine, and getting the cakes out in one piece was pretty tough. I would also suggest refrigerating the cake first - I didn't, and the crumbs came off into the frosting, which doesn't make for the best presentation. It also took EXACTLY thirty minutes for the cakes to bake - be sure to keep an eye on them, particularly if you have a temperamental oven, as I do. Happy Baking!
