This is a marble cake with a difference. It’s not just vanilla and chocolate cake mixed together, but white chocolate and dark chocolate cake. Unlike our classic chocolate cake (opens in new tab), it's also made with melted chocolate for a rich, moist texture and covered with decadent ganache which is simple to make with this recipe. Once you’ve perfected the ganache you can use it for other recipes too like cupcakes. The cake itself only takes 30 mins to bake on a low heat. If you’re serving this for a special occasion top with Maltesers or chocolate buttons for an impressive finish.

  14. When the cake is cool, place one onto your serving plate and pour half the ganache over. If the ganache has set too much, pop it into the microwave for 10 seconds.
  15. Place the second cake on top and pour the remaining ganach over, allowing it to flow over the edges.
