take heart... you CAN bake over an open fire...

cast iron cookware with lids to hold coals & wire hangers to either suspend over the fire or legs to sit in the coals.

I recently found an Australian campfire cookbook about outback cooking - but there are plenty of info here in the states about what we would refer to as cowboy or cattlemen roundup cooking. I've even seen a cooking show on campfire cooking. Big Dutch Ovens designed for campfire use. Bake bisquits or cakes, I'm sure a pie pan could fit in one.
