Key Details

  • Serves: 16-18
  • Prep time: 5 minutes
  • Cook time: 35 minutes
  • Difficulty: Easy


  • 350g plain flour
  • 75g cocoa powder
  • 250g caster sugar
  • 120g soft light brown sugar
  • 1 tsp bicarbonate of soda
  • 1/2 tsp salt 
  • 240ml cooled coffee (1 tbsp of instant with hot water)
  • 210ml corn oil (vegetable oil)
  • 1 tsp vanilla extract
  • 3 eggs


Mix your dry ingredients. Whisk in your wet ingredients.

Divide between two cake tins (I used two 20cm/8in cake tins – or sandwich tins will work) and bake at 180°C/ 350°F/gas 4 for 35 minutes or until a skewer comes out clean.


  • 70g good-quality dark chocolate (minimum 70% cocoa solids)
  • 140g unsalted butter, softened
  • 200g icing sugar
  • 1 tsp vanilla extract
  • milk, to loosen

Melt the chocolate in a bowl set over a pan of simmering water (do not allow the base of the bowl to touch the surface of the water). Allow to cool until the chocolate no longer feels hot to the touch.

Beat room temperature butter in an electric mixer or with an electric whisk until soft, fluffy and pale (you should notice a significant change in colour). Add the icing sugar and beat until smooth.

Fold in the melted chocolate until completely incorporated. Beat in a little milk, if necessary, to loosen the mixture.
