["Start with the cookie bars first:", "* Preheat oven to 375 degrees and line a 9x13"" pan with tinfoil or parchment paper, and grease lightly.", "* In the bowl of an electric mixer, cream together the butter and sugars until light and fluffy.", "* Add eggs one at a time, beating well after each addition. Mix in vanilla and combine.", "* In a separate bowl, whisk together flour, graham cracker crumbs, salt, and baking soda.", "* Add dry ingredients to butter mixture slowly, and mix until just combined.", "* Pour batter into prepared pan, and use a spatula to spread evenly", "* Bake for 20-25 minutes, or until a toothpick comes out clean.", "* Allow cookie bar to cool completely in the pan before removing", "Then the brownies:", "* Prepare brownies according to the box's instructions. Combine mix with additional required ingredients specified in mix package (typically water, eggs and oil). Spread into a tinfoil or parchment paper-lined and lightly greased 8x8"" pan. Bake according to package instructions.", "* Allow brownies to cool completely in the pan before removing", "Assembly:", "* Remove cookie bar from pan as 1 piece and place on a cutting board. With a large serrated knife, shave off the sides so you're left with a roughly 8x8"" piece. (There will be a lot of extras, but I'm sure you'll find a use for them). Carefully cut the 8x8 slab in half horizontally so you end up with 2 equally-sized thin 8x8 cookies.", "* Cut out an 8x8"" piece of cardboard and place one of the cookies on top of it. Then remove the brownies from the pan in 1 piece and place on top of the bottom layer cookie.", "* Fill a piping bag (or Ziploc bag) with fluff and cover the entire brownie in a relatively thick layer. The marshmallow will ooze down the sides, especially when you torch it, but that's what happens in real s'mores too so it just adds some appropriate character.", "* With a kitchen torch, torch the marshmallow uniformly so that each bite will have that toasted flavor. Be ready to blow out any bit that catches fire!", "* Allow the marshmallow to set for a few minutes, and then place the final layer of cookie on top. Use a knife to make a perforated line down the middle and a straw to make the holes if you desire."]
