The people have spoken and come down correctly on this issue so far: pie is the superior treat. Warm or cold, fruit or cream filled, with friends or alone, in a 1940s automat or eaten out of the pan on my couch while watching Planet of the Apes – pie is the desert of the people.
BUT, the one thing I will give cake that has no pie-based comparison is the fun of cake decorating. The unlimited possibilities for both deliciousness and comedy, often at the same time, are something that pie will never have.
