S'mores Cookie Bars

My older daughter has been asking me to make something that uses marshmallows in the recipe. And what's a better use of marshmallows than s'mores? I love roasting marshmallows and sandwiching it between chocolate and graham crackers, then eating its ooey-gooey goodness. Something about it is just so comforting. 

I found this recipe for S'mores Cookie Bars on Pinterest from Lovin' in the Oven. It uses a graham cracker cookie crust and marshmallow fluff that accomplishes the gooey part of a traditional s'mores. This definitely satisfies my S'mores craving.

1 stick unsalted butter, at room temperature
1/4 cup brown sugar, lightly packed
1/2 cup sugar
1 large egg
1 tsp. vanilla extract
1 1/3 cup all purpose flour
3/4 cup graham cracker crumbs
1 tsp. baking powder
1/4 tsp. salt
2 king-sized milk chocolate bars
1 1/2 cups marshmallow fluff (not melted marshmallows)

1) Preheat oven to 350 deg F. Grease an 8-inch square baking pan.

2) In a small bowl, whisk together flour, graham cracker crumbs, baking powder and salt. Set aside.

3) In a large bowl, cream together butter and sugars until light in color. Beat in egg and vanilla. Add flour mixture and continue beating on low speed until combined.

4) Press half of the dough in an even layer on the bottom of prepared pan. Place chocolate bars on top of dough. Spread marshmallow fluff over the chocolate bars. Place remaining dough in a single layer on top of the marshmallow fluff (the easiest way to do this is by flattening the dough into small shingles and then laying them together).

5) Bake for 30-35 minutes until lightly browned. Cool completely before cutting into squares.
