Preheat the oven to 350 degrees F and lightly grease and flour (or line with parchment paper) a 9×9-inch pan. Set aside.
Beat together the butter and sugars until well combined. Stir in the egg and vanilla extract until completely combined.
In a separate, medium-sized bowl, whisk together the flour, graham cracker crumbs, baking powder, and salt.
Gradually stir the dry ingredients into wet until completely combined
Press approximately ⅔ of the graham cracker cookie dough evenly into the bottom of your prepared pan.
Spread the marshmallow fluff evenly over the top of the cookie dough crust. Portion the milk chocolate bar quarters evenly over marshmallow fluff and press gently into the surface.
Drop the remaining cookie dough over the surface of the s’mores bars. Use your fingers to gently spread the dough over the surface. It’s fine not to cover the entire surface area.
Sprinkle with milk chocolate chips.
Bake at 350 degrees F for 27 to 30 minutes, or until the cookie layer is fully cooked, and the marshmallow and chocolate has melted.
Allow to cool before cutting and serving.
