THESE WERE SO GOOD!!!!! I got this recipe from http://theidearoom.blogspot.com/2009/11/smore-brownies.html
S'more Brownies

Crust:
6 TBS unsalted butter, melted
1 1/2 cups crushed graham cracker crumbs
2 TBS sugar
a pinch of fine salt

Brownie:
8 TBS (1 stick) unsalted butter
4 ounces unsweetened chocolate, chopped (I didn't have any so I just used cocoa powder)

1 cup packed light brown sugar

3/4 cup white sugar

1 1/2 tsp pure vanilla extract

1/2 tsp fine salt

4 large cold eggs

1 cup all purpose flour

Topping:

4 cups large marshmallows (I used half a bag of mini marshmallows)

Position rack in lower third of oven and preheat to 325 degrees. Line an 8x8 pan with foil so it hangs over the edge 1 inch.

*Crust: Lightly butter the foil with some of the melted butter, stir the rest of the butter with the graham cracker crumbs, sugar and salt in a medium bowl. Press the mixture evenly over the bottom of the pan. Bake for 20 minutes or until golden.

*Brownies: Put butter and chocolate in a medium microwave safe bowl, melt on 75% power for 2 minutes, stir, microwave another 2 minutes until fully melted (or use a double boiler). Since I didn't have the chocolate I just mixed the butter and cocoa. Stir brown and white sugars, vanilla, and salt into melted chocolate. Add eggs and beat vigorously to make a thick glossy batter. Add flour and stir until just incorporated. Bake until crispy and a toothpick comes out clean, 40-45 minutes. Put rack 6 inches from broiler on low, layer the marshmallows on top and broil until they are golden, for about 2 minutes (keep a close eye on them cuz it'll look like nothing is really happening and then it will all of a sudden be done :) that is always how it seems when I'm broiling anything!) Use the foil to take them out of the pan and let them cool.
