Flying Monkey, a bakery in Philadelphia, created a cake dubbed the "pumpple". It's a pumpkin pie and apple pie baked between chocolate and vanilla cakes and covered with buttercream icing:

This oversize creation weighs in at a whopping 15 pounds and measures more than a foot tall. And at 1,800 calories a slice, it's not for the faint of heart.[...]
It starts with the pies, which it par-bakes. The half-cooked pumpkin pie is dipped into chocolate cake batter and baked. The apple pie and vanilla cake get the same treatment and are baked on top of the chocolate cake. Its massive size means that it spends hours in the oven. Homemade buttercream is then — literally — the icing on the entire cake.

If you want to celebrate cooking, or wonderful tastes, or the season, a perfect pumpkin or apple pie would be fine, although, it would not get featured on a big blog on the internet.
