I wanted to bake a special cake for my husband's birthday celebration a few days ago and I knew that the Diamond Head cake from the book Extraordinary Cakes would be perfect for this occasion. Since my hubby loves Mauna Loa Macadamia Chocolates, I was certain that he would love the Hawaiian-inspired flavors of this cake as well. I also happen to love this chocolate-macadamia combo so I was really looking forward to having a slice of this cake all to myself. I also found it hard to resist not licking my fingers and baking utensils after making the individual components most especially after I made the ganache, vanilla bean custard and macadamia brittle! :-) Actually, the three components on their own already make for a very satisfying treat.
