Since I caught it before it did any damage except for some charred marshmallows, I feel that this actually makes my brownies more successful

you are correct

Disappointingly, it's not actually very good. The brownie to smores ratio is off to my taste.

Next time I think I'll layer in marshmallows and graham crackers at the bottom and cut the brownie recipe in half

or just start a fire and make regular s'mores
