Chocolate Guinness Cake with Irish Cream Frosting

guinness cake

Living in Dublin we occasionally have the pleasure of playing host to friends and family visiting the emerald isle for the first time. One of the outings we do with most visitors is a trip to the Guinness Storehouse, the original brewery of the famously Irish stout.

The building is impressive and the tour is interesting. The best bit however is the 360 degree view of Dublin from the bar at the top. I always feel a bit bad when we get to the top and I hand over my drink voucher for a soft drink instead of a pint…

3 years in Dublin have not made me a Guinness fan. I love to watch the swirling foam as the pint is poured and starts to settle. I think the thick creamy head looks delicious but I just can’t bring myself to drink more than a mouthful or two. Too strong. Too bitter. Not at all my kind of thing.

This chocolate guinness cake on the other hand is exactly my kind of thing! Please make this cake. Seriously. It’s DELICIOUS.
This is what I would call a “mud cake” recipe – soft, moist and fudgy with a really good chocolately flavour. For fellow skeptics and beer-haters I can assure you that the finished cake doesn’t taste like Guinness at all. I promise, not even a teeny bit. The stout seems to just boost the richness of the chocolate and the deep dark colour.
After making this cake, the recipe has moved up to #1 spot in my list of favourite cake recipes. The perfect special occasion cake for adults.

Chocolate Guinness Cake

Cake recipe adapted from here and frosting and ganache inspired by these cuppies


  • 250ml Guinness
  • 140 grams butter
  • 1/2 cup cocoa powder
  • 2 cups granulated sugar
  • 3/4 cup plain greek yoghurt (or sour cream)
  • 2 eggs
  • 2 teaspoons vanilla essence
  • 2 cups flour
  • 2 1/2 teaspoons Baking Soda


Preheat the oven to 175C and grease and line a large round cake tin.

Put the guinness and butter into a saucepan. Heat until the butter is melted then remove from heat. Whisk in the sugar and cocoa powder.
In a separate bowl whisk the sour cream and eggs together. Add the vanilla essence and stir in the guinness and butter. Lastly add the flour and baking soda and mix until smooth.

Pour the batter into your lined cake tin and bake for 45 to 60 minutes or until cooked through. Cool in the tin on a cooling rack.
Once cooled carefully remove from the tin and peel off the baking paper – the cake is very soft.

Baileys Frosting and Ganache

  • 1/3 cup cream
  • 1 tablespoon butter
  • 1 teaspoon Irish Cream eg. Baileys
  • 120 grams dark chocolate

Heat the cream in a saucepan until steaming then remove from heat. Add the roughly chopped chocolate and leave to sit for 5 minutes. Stir the chocolate in until a smooth glossy sauce is formed. Add the butter and baileys and stir until combined. Cool the ganache until is thickens enough to pour over the top of the cake without sliding off the edges! Cover the top of the cake with ganache and put in the fridge so the ganache can harden further.

  • 50 grams softened butter
  • 2 to 3 cups icing sugar
  • 3 tablespoons Irish Cream eg. Baileys

Mix the icing ingredients together. Add more icing sugar or baileys as desired to form a smooth, spreadable frosting. Ice the cake and decorate as you wish. I left the sides bare and used a fork to swirl the icing into little peaks (a bit like the creamy top on a pint of dark guinness). For maximum enjoyment, serve with a glass of baileys over ice!
