Instructions

• 1 Preheat oven to 350°F. Line a 9x9 pan with foil or parchment paper (for easy removal) and grease it. Set aside.
• 2 In a large bowl, combine flour, graham cracker crumbs, baking powder, and salt. Set aside.
• 3 Using a hand mixer or stand mixer fitted with the paddle attachment, beat butter and brown sugar until smooth and creamy, scraping the sides and bottom of the bowl as needed. Add egg and vanilla and beat to combine. Add the dry ingredients and beat until combined.
• 4 Scoop out two thirds to three quarters of the dough and press it into the bottom of the pan.The dough will be sticky. I recommend moistening your fingertips with water to easily flatten it out. Add all the marshmallow creme. Spread it into an even layer very carefully, without disturbing the cookie dough underneath. Sprinkle with the chocolate chips, setting aside a few tablespoons of chocolate chips for topping the bars after baking. Using the remaining cookie dough, press small portions into flat irregular shaped pieces and place on top of the marshmallow/chocolate layer.
• 5 Bake for 20-22 minutes, until the edges are beginning to turn golden brown and the marshmallow creme has puffed up. Place the pan on a wire rack. If desired, you can use a kitchen torch to add some extra color to the exposed marshmallow creme. Gently place the reserved chocolate chips around the top. Cool completely before cutting, about two hours.
