Chocolate sponge cake

  1. Grease 2 deep, 20 cm round cake tins, lined with baking paper.
  2. Sift the 3 flours, cocoa and pinch of salt 3 times to aerate.
  3. Preheat the oven to 180°C.
  4. Using an electric mixer, beat eggs and sugar in a large bowl on medium-high speed for 6 minutes, or until mixture is thick, pale and has tripled in volume. Gradually sift the flours over the egg mixture while at the same time folding in with a large metal spoon until just combined.
  5. Divide mixture between prepared tins. To level the batter, gently spin the tins on kitchen counter. Bake for 20 mins. or until the cake has shrunk slightly from the sides and springs back when touched gently. Turn out onto wire cooling rack that has been lined with baking paper.
  6. Carefully peel the baking paper from the base and then leave to cool. Bring the cream and milk to the boil. Remove from the heat and add the chocolate whilst stirring with a wooden spoon, until the chocolate has melted. Once the chocolate has melted the sauce can be served hot or set aside to use cool.
