This is a light yet indulgent chocolate sponge infused with orange zest and juice, then layered and topped with a glossy chocolate orange icing. Mary Berry’s version ensures the sponge stays soft while the icing enhances the flavour with a citrus twist.
175g self-raising flour
175g caster sugar
175g butter, softened
3 large eggs
40g cocoa powder
1 tsp baking powder
Zest of 2 oranges
2 tbsp orange juice
100g milk or dark chocolate, melted
75g butter
150g icing sugar, sifted
2 tbsp orange juice
Extra orange zest or curls of chocolate, for decoration
Preheat oven to 180°C (160°C fan). Grease and line two 20cm round sandwich tins.
Place butter, sugar, eggs, flour, cocoa, baking powder, orange zest, and juice into a mixing bowl. Beat until smooth and creamy.
Divide mixture evenly between tins and level the tops. Bake for 20–25 minutes until risen and springy. Cool for 5 minutes, then transfer to a wire rack.
Melt chocolate and butter together, then allow to cool slightly. Beat in icing sugar and orange juice until smooth.
Spread icing over one sponge, top with the second, and cover the top with the remaining icing.
Finish with grated orange zest or chocolate curls for a decorative touch. Serve and enjoy.
