I cooked a couple of times but I was just aiding a colleague that also brought all the ingredients and had the know-how. And I have a poor memory, obviously.
How do you cook yours? What recipe do you use? Details are very much appreciated.
I managed to get the recipe from an experienced hiking friend that I think is closer to what I'm looking for:
Here are two dessert recipes I like to make while camping:
Heat up some coals, pour the peaches into a dutch oven, and pour the cake mix evenly over the peaches. Put the top on the dutch oven (including coals on top), bake until it's done: The peach syrup should bubble over into the cake mix over much of it, the rest of the cake mix should be just starting to brown. How long depends a lot on your fire/coals.
If you're hiking and a dutch oven is too much, you can probably get away with putting it in a fairly wide pan on a camp stove.
You can also experiment with other fruits and cake mix flavors; but note that the heavy syrup is important, it keeps the syrup below the cake mix in a place to bubble up properly.
Melt the butter in a dutch oven. Pour in the sugar, mix quickly, flour, mix quickly, eggs, mix quickly and then thoroughly. Put the lid on, bake until it's done.
I imagine this doesn't translate to a camp stove quite as well as the peach cobbler, but if you have a pot that can handle the temperature and you don't mind getting it dirty (and possibly melting, if you misjudged its sturdiness) you can try putting it in a pit surrounded (beyond a bit of a gap) by coals piled up.
Also, this one can obviously be scaled down to smaller portions (e.g. 1/4 lb of each) if you are in a smaller party.
