      For the marble cake:

    1. Preheat the oven to 160 C / Gas 3. Lightly grease a 17x9cm (2 lb) loaf tin and line with baking paper.
    2. Beat the softened butter, sugar, flour, baking powder, eggs, milk and vanilla extract until well blended.
    3. Transfer half of the cake mixture into another bowl and set aside. You will use this to make the chocolate cake mixture.
    4. Mix the cocoa powder and enough warm water (about one or two tablespoons) to create a smooth chocolate sauce. Stir this into one of the vanilla cake mixtures until evenly mixed.
    5. Spoon the vanilla and chocolate cake mixtures into the lined loaf tin, alternating between the two mixtures until both portions are used up.
    6. Bake in the preheated oven until a skewer inserted in the centre comes out clean or the cake has begun to shrink away from the sides of the tin, about 45 to 50 minutes.
    7. Transfer to a wire rack to cool slightly; remove the lining paper and leave to cool completely before icing.
    8. To make the icing:

    9. Stir warm melted butter and cocoa powder together; add milk and icing sugar and continue to mix until evenly blended and slightly thickened.
    10. Spread the chocolate icing over the top of the cooled cake and leave to set.
