Now that I had pie chart cookies, I needed to make a representation of the fecal sample. I briefly considered making a realistic poo log, but quickly decided against it. After all, I wanted people to actually eat the cake. I spent enough time thinking about making a bloody poo cake to fully plan it out (chocolate-frosted red velvet cake with a cherry-based filling, so that when cut open red chunks would ooze out) but ultimately decided against that as well. The Human Microbiome Project only reported on healthy humans. Finally, I decided on a stylized poo made from chocolate fudge cake and a chocolate and Nutella frosting.
