Chocolate Guinness Cake with Baileys Buttercream

Chocolate Guinness Cake

I made this Chocolate Guinness Cake for the first time on St. Patrick’s Day. It was so yummy that it I knew I would be making it again and again. I’ve now made it countless times! This Chocolate Guinness Cake has the perfect light and moist chocolate sponge, and the Baileys buttercream is to die for! I could swim in a vat of the stuff! This would go in my top five favourite cakes of all time without a doubt, and I always want it as my birthday cake every year without fail. Best of all, it’s so easy to make and decorate. I’ve made a stencil with the harp logo to decorate the cake, but of course you don’t have to do this, that’s just me being extra!

Step by step…

In a mixing bowl I whisked the dark brown sugar and vegetable oil together. Then I whisked in the eggs, and the Guinness.

In a separate bowl I measured out the self raising flour, cocoa powder, baking powder and bicarbonate of soda, and salt. I added it to the mixture bit by bit and whisked in. Finally I mixed in the melted dark choolate.

I poured the mixture into a lined and greased deep 8″ cake tin. It baked for 40 minutes.

To make the Baileys buttercream I mixed together the butter, icing sugar and Baileys irish cream. Try not to eat it all before you put it on the cake!

To make my stencil decoration I traced an image of the harp logo from my laptop onto paper, stuck it onto a piece of card, then used a craft knife to cut it out. I held the cardboard over the cake and sprinkled cocoa powder over it. I recommend using a circular piece of cardboard that is bigger than the cake as I often sprinkle over the sides of the stencil by accident – sadly I didn’t have the foresight to make it circular!

    1. Thank you! I didn't know how to decorate it as the cake itself is so fab, the first time I just sprinkled some green nonpareils on top but it did nothing for it.

  1. Oh yum! Chocolate Guiness has been on my to bake list for ages and with Baileys buttercream that moves it up a few notches!
