When I was a kid we had a couple Japanese exchange students stay with our family and they would often bring kokeshi as a gift. I still have those lovely dolls and wouldn't turn down a cookie version either!
Sometimes you only want one little cookie. Sometimes you only want one little hard peppermint. I think this philosophy stretches across a lot of disciplines. Sometimes you only want one little cup of coffee, kiss from the dog, shot of tequila, chocolate on your pillow... I could go on and on.
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.
