The ultimate s’mores brownie

Graham cracker crust:
1. Preheat the oven to 350°. Combine all crust ingredients, and press down tightly into a pan.
2. Bake for 10 minutes.
3. Prepare your brownies according to their insurrections, and pour on top of the graham crackers.
4. After baking, let the brownies cool to room temperature before adding the marshmallow layer.

Marshmallow fluff topping:
1. Add egg whites, sugar, and cream of tartar to a double boiler, or just a heat proof dish over a small pan of a few inches of boiling water.
2. Stir as it heats until it reaches 160° or the sugar is full dissolved.
3. Add the vanilla, and mix on high speed until stiff, glossy peaks form.
4. Add on top of brownies, and if you have a kitchen torch, toast the top.
