I love them plain or frosted.
And I will make a heretical statement about cake, in general. The fashionable thing to say is that pie beats cake. 75% of people will say that. I've had many more bad pies in my life than cakes. Overbaked and too crusty. Odd-tasting fillings. And there are few types of cake I will find offensive to my taste buds, but there are scads of types of pies that I don't like. It's hard for me to find a bad chocolate cake with vanilla frosting, but I can find many bad apple pies or cherry pies because the fruits used were subpar.
