"'The best chocolate cake I've ever had!' You'll hear comments like this and more when you serve this ultra dark, rich chocolate cake with its luscious chocolate icing. This recipe is adapted from one created by Diana, the talented editor of Allrecipes' UK site (allrecipes.co.uk). Use a chocolate bar with 74 percent cacao to intensify the chocolate flavor (not baking chocolate), and don't wait until St. Paddy's Day to make it!"

  1. Preheat oven to 350 degrees F (175 degrees C). Grease 2 9-inch cake pans, and dust with 1 tablespoon cocoa.
  2. In a heavy saucepan over low heat, heat 1 cup of stout beer, 1 1/4 cup of unsalted butter, 4 ounces of dark chocolate, and the superfine sugar just until the butter and chocolate have melted; stir to blend mixture, and cool slightly.
  3. Beat the eggs and creme fraiche together in a large mixing bowl; gradually stir in the flour and baking soda. Add the melted chocolate mixture in small additions, stirring to blend. Pour half the batter into each prepared cake pan.
  4. Bake in the preheated oven until the top of the cake bounces back when touched lightly with a finger, about 40 minutes. Cool the cakes on racks.
  5. To make the icing, place 1/2 cup of unsalted butter, 4 ounces of dark chocolate, and 5 tablespoons of stout beer in a heavy saucepan over low heat, and cook, stirring, just until the chocolate has melted; stir to blend mixture. Remove from heat, and cool slightly.
  6. Sift the confectioners' sugar. In a mixing bowl, blend the cream cheese, 1/3 cup of cocoa powder, and vanilla extract until smooth; gradually beat in 1/2 cup confectioners' sugar. Pour in the cooled chocolate-stout mixture and mix well. Add confectioners' sugar until the icing is your desired consistency, adding more if you like a stiffer icing.
  7. Place a cake on a serving plate, and smooth about one third of the frosting over the cake top. Place the second cake onto the frosted layer, and spread remaining two thirds of the frosting over the top and sides of the cake.


  • Cook's Notes
  • Sour cream can be substituted for the creme fraiche. Instead of buying superfine white sugar, make your own by grinding regular sugar in a blender or use a mortar and pestle.

The cake is a 5 star cake. I had to knock the frosting down a bit tho, thus the 4 star rating. The only thing I changed was to make cupcakes, but other than that I made this cake EXACTLY as in...

I seriously questioned the unusual execution of this recipe but I followed through and was rewarded with a rich and buttery, light chocolate cake. I was so hesitant to make the beer infused fro...

This cake is yummy. The cake isn't very sweet but the icing brings the sweetness in. Loved the dark chocolate.

This was the ugliest cake I've ever made--it fell apart when I took it out of the pans and crumbled like crazy! I used a lot of icing as glue to piece it together; it really looked a mess. The...

Not too rich, very tasty. My friends and I all tasted banana for some reason? Maybe its in the Guinness. I ended up with probably twice as much icing as I could fit on the cake, I will cut t...

The cake was very tasty, although very dense. The following day it had the consistency of very dense brownies rather than cake. But it was very yummy!

I used this frosting with a different cake because I didn't have creme fraiche or superfine sugar. best frosting I have ever made!

I made this recipe exactly as directed and I found this cake dense, with the Guinness giving it a funky flavor. The frosting was flat. It definitely needed salt. I won't ever make this again....

When I beat the flour mixture together, it immediately clumped up like bread dough. Putting the rest of the wet ingredients in that point didnt help. I've made very few cakes from scratch, but i...
