Blue muffins.

Before bed when we are snuggling on the couch and telling stories she always requests a story with blue cupcakes and a blue animal (cat, dog, hippo, or elephant typically). The girl is obsessed with the color blue (and her imaginary animal friends!). So when I told her we were going to make banana muffins she of course requested blue ones. They didn't turn out super blue but it was enough to make her quite happy.
