Is the Cake made of Chell?

The ingredients don't mention human, still there could be more than one cake

Someone posted a video on YouTube where they used a cheat to block out the boss music as well as the stuff GLaDOS was saying during the final battle. Then you got to hear her Logic Core (the sphere with the blue eye) recite the entire recipe. It sounds good until you hear what the garnish is made of! Here's the link: http://www.youtube.com/watch?v=P9R4rsWNk6s. The video doesn't contain any spoilers other than mentioning that you are fighting GLaDOS.

A friend will bail you out of jail. A true friend will be in there with you!
