Chocolate Cake with Dark Chocolate Ganache and Crunchy Oat Clusters

I made this cake for an old friend at work who was leaving England for Brazil. This simple chocolate cake is a recipe by Hersheys that i have slightly modified. I made it special by topping it with dark chocolate ganache and cruchy oat clusters.
