Chocolate celebration cake

When it comes to a celebration, chocolate cake is always a popular choice to serve, but what happens when you have people with varying dietary requirements to think about? Do you create hard work for yourself and make them something different, give them something shop-bought or pretend you forgot altogether!? Well, let that be a thing of the past. This cake could be your saviour as it ticks all the dietary requirement boxes, but the most important thing is that it tastes AMAZING.
