PTA founder's day cake (or: what to do with a lot of spare cake)

Once upon a time in February, I had a lot of extra cake on my hands. Three, 12" round layers, to be exact.

Luckily for me, our school was celebrating PTA Founder's Night. And what better way to celebrate than with a giant cake that will feed 50 people?

I quickly frosted it with delicious chocolate frosting and ran it over to school. Voila!
