I'd never heard of a Hummingbird cake before I made one the other week. It's really moist and has pineapple and bananas in it, interesting! Even though I'd automatically go chocolate when baking a cake, the hummingbird turned out rather tasty :)
The pineapple flowers on top were really fun to make too, you just cut some pineapple slices, put them in a muffin tin and bake for ten or so minutes. In the oven they loose their moisture, crisp up and look surprisingly like flowers! Use that handy Google for more instructions :)
