Grease and line a 30x23cm/12x9in baking tin with baking paper.Break the eggs into a large mixing bowl. Add the cocoa, flour, baking powder and sugar. Stir a little using a wooden spoon then gradually mix in the oil and beat until combined to give a thick batter. Once smooth, stir in the grated beetroot.Spoon into the prepared tin and bake for about 35 minutes, or until risen and springy to the touch. Remove and set aside to cool before icing.To make the icing, place the chocolate in a heatproof bowl. Add the cream and place the bowl over a saucepan of gently simmering water (do not allow the water to touch the bowl). Stir until the chocolate is melted, smooth and glossy. Leave to cool a little so that it is a thick pouring consistency (this won’t take long depending on room temperature). Pour the icing over the cold cake and spread it out to cover the top of the cake completely. To decorate, melt the white chocolate in a small bowl set over a saucepan of hot water. Spoon into a small piping bag fitted with a fine nozzle or a small food bag with a tiny corner snipped off. Pipe the chocolate in parallel lines across the cake, about 2cm/¾in apart. Using a cocktail stick, drag through the white chocolate in opposite directions across the cake to give a feathered effect. Allow the chocolate to set a little before cutting into 12 small squares.
