It's funny where inspiration is found these days. I was reading an article about how Tom Cruise bought a lot of his friends a specific cake for Christmas. It was a white chocolate coconut bundt cake and that just sounded delightful to me.
Full disclosure, I first tried this cake as a bundt cake and it failed miserably. In fact, I can't recall a time when I've ever successfully extricated a bundt cake from a bundt pan. I've tried the tricks. I think my pans are just really old without modern non-stick technology.
I added a little bit of cinnamon to this cake which I think just elevated the basic sponge and really goes with the chocolate-coconut topping. It's a delicious cake-y version of those coconut Ferrero Rochers and it hits the spot.
This makes one sheet cake. If you want to make a three tier cake, increase the recipe by 1/3 (so 225g butter, 180g sugar, 3 eggs etc etc).
