S'mores Cookie Bars

1/2 c. unsalted butter, room temp
1/4 c. brown sugar
1/2 c. white sugar
1 large egg
1 tsp. vanilla
1 1/3 c. all-purpose flour
3/4 c. graham cracker crumbs (about 8 crackers)
1 tsp. baking powder
1/4 tsp. salt
4 regular size milk chocolate bars
1 1/2 c. marshmallow fluff

Preheat oven to 350 degrees. Grease or line an 8 inch square baking pan.
In a large bowl, cream butter and sugars until light. Beat in egg and vanilla.
In a small bowl, whisk together flour, graham cracker crumbs, baking powder and salt. Add to butter mixture and mix on low speed until combined. Divide dough in half and press half of dough into an even layer on the bottom of the prepared pan. Don't worry if it seems thin, the baking powder will allow it to rise.
Place chocolate bars over dough (break to fit a single layer) then spread marshmallow fluff over the chocolate bars.
Finally top the fluff with remaining dough by forming the dough into sheets with the palms of your hands and laying it down. Don't worry if dough doesn't cover everything. It will spread.
Bake for 30-35 minutes, until lightly browned. If the top is browning too quickly, cover with foil for the remaining time. Cool completely before cutting the bars. If they aren't cooled completely, they will crumble when cut.
Makes 16 to 20 bars
