When my brother was at boarding school (years and years ago) they all had a choice of birthday cake that the cook would make for them. He would always choose the Mars Bar cake – chocolate cake with chocolate sprinkles around the outside and a layer of caramel on top etc. I still remember him telling us about it at the time. The boys clearly thought it was brilliant and a highlight when either themselves or their classmates had a birthday and they could all enjoy this culinary delight.
A friend of mine loves caramel so her birthday seemed like a good time to experiment with my own interpretation of a Mars bar cake. It was a chocolate sponge cake with caramel filling, covered in chocolate buttercream, with slices of Mars bar around the bottom and crushed Mars bar on top with caramel drizzled over. When I was decorating the cake, I was in my own little world and it was only when I finished that I had a sudden realisation that it might in fact be inedibly sweet. Luckily (with small pieces) it was delicious and sweet but without being too sickly – phew!
