Bake a deliciously naughty chocolate fudge cake, with orange for extra bite.
Pre-heat the oven to 180C/350F/Gas 4. Grease and line two 20cm/8in sandwich tins.
Beat the butter and sugar in a bowl until light and fluffy.
Beat in the eggs, and then the soured cream until well combined. Sift in the flour, baking powder, bicarbonate of soda and cocoa powder. Fold in the orange zest.
Divide the mixture between the two 20cm/8in sandwich cake tins and then bake for 30-35mins. (Test by inserting a skewer through the centre of the cake. If it comes out clean, the cake is ready. Leave to cool.)
For the frosting, add a little water to the cocoa until it forms a paste. Stir the mixture into the melted chocolate and beat in the cream until well combined.
Spread the frosting over one cake and top with the other cake. Transfer the cake to a serving plate and ice the cake all over using a pallette knife.
Serve with berries and cream.
