Don't you just want one...
Wipe that drool off your face.
The recipe is from Erica's Sweet Tooth (best baking blog EVER!) and I'll let you get it from there. Please ignore the superiority of her photos over mine-- not everyone can be a dental student, amazing baker, AND excellent photographer... some of us have LIVES.
However, I'm not fully convinced about this recipe because there's just so much darn chocolate (gasp!). I promise you I am a woman it's just that chocolate doesn't do it for me, I love the graham cracker and marshmallows. I attempted half the batch normal then topped the second half just with marshmallows-- the presentation left something to be desired. When I go for it a second time I think I'd like to sprinkle a fewer amount of mini chocolate chips (or none) in the batter to preserve the graham cracker flavor.
