A few days after I made my PB&J post I saw this wonderful contraption on Geekologie:
The Cakewich is basically a large silicon mold so that you can make slabs of cake in the shape of Wonderbread. And then make giant peanut butter and jelly sandwiches. I want to try making my favorite chocolate chip banana bread in the Cakewich and then making a PB&J with it…. Yum!
