Yields: one 8x8 pan of brownies
1 family-size (13x9) box mix of fudgy brownies, plus eggs, oil, etc. called for in instructions
semisweet chocolate chips
stacker marshmallows (or just plain mini marshmallows)
Preheat oven to 325F. Grab an 8x8 baking dish and line with parchment paper, and set aside for now.
In a medium bowl, prepare brownie mix as directed. Get your prepared baking dish, and pour in about 1/3 of the brownie batter, using a spatula to make sure the whole bottom of the dish is evenly covered. Make one even layer on top of the batter with the graham crackers, followed by a layer of marshmallows, and a scant layer of chocolate chips. Top with remaining brownie batter.
Bake for about 45 minutes, until toothpick comes out sorta clean... the chocolate chips and marshmallows will make it hard to tell, but don't overbake!
Let the brownie rest for about 10 minutes before removing from the pan, and wait at least one hour before cutting! The marshmallows make the brownie super gooey, so if you don't wait, you will definitely regret it, not to mention you will burn your mouth. ;)
I wish we had taste-a-vision... you wouldn't hesitate one second to make these! :)
