How far can I take a brownie recipe before it fails?
I'm eight or so days away from departing on a loooong trans-Europe camping trip, and currently I'm gathering as many recipes for baking as I can - pitas, Irish soda bread, bannock, mantou buns so far - but I have a rather silly experiment I'm like to try. Perhaps some guidance would help... I'll be preparing everything with a Coleman camp stove, but I have a pretty severe sweet tooth. I also have a basic recipe for brownies, essentially flour, egg whites, joghurt or milk, baking soda and powder, sugar, and vanilla or chocolate. It's largely a low-fat sweet quick bread, bakes for 20 minutes or until the toothpick-in-the-center method verifies it's done.
What I'm wondering is whether it would be possible to pour the batter into a pan - a griddle pan, saucepan, cover it on the stove, and bake it that way. Does anybody have any thoughts? If so, what heat would you recommend? How long would it take? Or is this the sort of thing that would give me a tummyache?
Any help is appreciated, and until then, blessings!
