I can’t help but see this as a metaphor for the people in Dean’s life. Pie is something Dean loves. He knew he wanted pie, he asked for pie. Pie is simple, cake is layered and complex. But the pie is not there. He has cake instead, and in this instance it’s a substitute. He doesn’t want cake right now, but he got it anyway. He feels the loss of the pie, but he has to make do with the cake. He does like cake but it’s not the same as pie, it will never fill that emptiness inside him that only pie can fill.
Hint: Cas is pie. Sam is cake.
