For the sponge

  • 75 g Dark chocolate melted
  • 125 g Dark brown sugar
  • 85 g Vegetable oil
  • 1 Egg large
  • 1 tsp Vanilla extract
  • 150 ml Guinness
  • 175 g Self raising flour
  • 25 g Cocoa powder
  • 1 tsp Bicarbonate of soda
  • ¼ tsp Salt

For the buttercream

  • 65 g Butter
  • 170 g Icing sugar
  • 2-3 tbsp Baileys

For decoration (optional)

  • 1 tbsp Cocoa powder


  • Pre-heat your oven to 150C Fan/160C/325F/Gas Mark 3, grease and line a deep 8" tin (make sure the sides of the tin are at least 2" tall)
  • Melt the chocolate first. Place in a microwave safe bowl and heat for 30 seconds, stir, then heat in 10 second intervals, stirring between each one. Once fully melted, set aside to cool.
  • In a mixing bowl, whisk together the vegetable oil and dark brown sugar
  • Add the eggs and vanilla extract and whisk in
  • Add the Guinness bit by bit, mixing well after each addition, don't worry if it curdles a bit
  • Measure the self raising flour, cocoa powder salt and bicarbonate of soda out in a separate bowl and add into the mix bit by bit, mixing well after each addition
  • Finally, stir in the dark chocolate
  • Pour the mixture into the tin and bake for 30-35 minutes or until a skewer inserted in the centre comes out clean
  • Leave it to cool fully on a wire rack
  • To make the Baileys buttercream mix together the butter and the icing sugar. When it starts to come together, add the Baileys and mix until smooth. If the buttercream is too stiff then you can add some more Baileys to it!
  • Smooth the buttercream on top of the cake using a palette knife and decorate as you wish
  • Store leftovers in an airtight container in a cool place and eat within 3 days
