You see, it's not just a matter of a Vanilla sponge cake with some white butter frosting covered in Coconut Flakes. Oh no! A real Coconut cake is Coconutty goodness, layered upon Coconutty goodness... for a sense of it watch the Good Eats Episode dedicated to it.
A nice Coconut cake, as this lovely present is, should taste of coconut throughout and not as you're sweeping up the last bit of Coconut flakes that fell off while you were eating. I'm not saying that L made Alton Brown's cake but if that's any guide, I tip my hat to your effort and your most generous gift!
