I fear that if I had a little donut friend in my purse all the time, I'd get hungry constantly! Maybe if they doubled as pez dispensers?
I'm sure we've all dreamed from time to time about having a tasty treat so large that we could essentially live on it. I'd like to think that I'd have enough restraint to not eat until comatose. Oh who am I kidding? I'd end up flat on my back like Homer there in about ten minutes.
When I was a kid my mom had a cookbook all about how to make creative cakes with nothing but a round cake pan, a bundt pan and a square pan. She made caterpillars and castles and Snoopy and all sorts of amazing creations but I don't think I ever saw a donut. It's so simple it just slipped under the radar.
