A grown-up cake which is two chocolate traybakes that are filled ... surface of the cake is completely covered. Light some birthday candles, if you like, and cut into squares to serve.

This Happy Birthday cake doesn’t just look ... All the fix-ins, including chocolate cake mix, sprinkles and a candle are included. They just have to add an egg, oil and water!

Andrew used his Gran’s recipe for a classic light chocolate cake and topped it with chocolate icing, chocolate shards, hazelnuts and raspberries for a spectacular finish fit for a birthday.
