I noticed you were trying a new technique for baking brownies.  How did it turn out?  We have a pretty good technique.  On our trips we use store bought brownie mix, mix it up according to instructions and then put the mix in a turkey bag.  The turkey bag is then put in a pot of boiling water to cook.  The brownies fluff up right inside of the bag.  Works pretty slick but of course the brownies must be spooned out.
