WTF? Really dude? Who are you kidding? Just because a cake is made doesn't mean you HAVE to eat it!!

This IS what is right in the world, ingenuity, thinking outside the box, having the desire to try something different, having the will to not just follow all the misguided health nuts that really don't know a thing about true health and would rather just lump everything that they wish they could have or have problems with because they are jealous into the "wrong" catagory.

Just because it exists, doesn't make it evil.
It takes someone evil to make something evil.

Ok, let me put a few things to rest,
Firstly no one is saying it isn't possible. Clearly it is.
Secondly this is:
3 baked pies, baked into 3 layers of cake that is then tiered and frosted.

It was not tiered then covered again in cake batter and baked again as the title will have you believe. This would not be realistic as you would overcook the already baked cakes during the second baking.

Now If I had to guess, I would figure that what REALLY happened was this.
3 frozen pies were defrosted to a temp that would allow them to bake to completion within the timeframe it would require the surrounding cake to bake to completion. Those 3 layers were then tiered and frosted, making this monster of a Pi-Cake quite easy to duplicate.

Enjoy.
