For the cake

  • 250ml Guinness (or other dark beer. Cola also works!)
  • 250g butter
  • 75g cocoa powder
  • 400g caster sugar
  • 150ml organic soured cream
  • 2 RSPCA Assured eggs
  • 1tbsp vanilla extract
  • 275g plain flour

For the frosting

  • 300g organic cream cheese
  • 150g icing sugar
  • 2tsp cornflour
  • 100ml organic double cream

Like a smooth dark pint with a light and fluffy head, our chocolate and Guinness cake is a great (and slightly sweeter) way to celebrate St Patrick’s Day. Once you're done with the hard work, you can sit back and enjoy it with a beverage of your choice. 

  • Preheat the oven to 180°C/160°C fan, and grease a large springform tin. Make sure you line the tin with greaseproof paper as the mixture is heavy and could leak through the bottom.
  • Slice the butter block and add to a large, wide saucepan, then pour in the Guinness. Gently heat (don’t boil) until the butter has melted, then whisk in the cocoa powder and sugar.
  • Beat the soured cream with the eggs and vanilla extract in a separate bowl, and then pour the mixture into the saucepan. Whisk in the plain flour and bicarbonate of soda.
  • Pour the cake batter into the greased and lined tin and bake for 45 minutes to an hour. Leave to cool completely in the tin on a cooling rack, as it is quite a damp cake.
  • When the cake is cold, transfer it to a cake stand or a plate and leave whilst you make the icing. Lightly whip the cream cheese until smooth, sieve over the icing sugar and cornflour and then beat to combine.
  • Beat in the double cream until you have a spreadable consistency, making sure not to over whisk.
  • Spread the icing on the top of the cake so that you get a frosting which resembles a frothy Guinness top!
