S'mores Bars

1/2 cup butter, room temperature

1/4 cup brown sugar

1/2 cup sugar

1 large egg

1 tsp vanilla extract

1 1/3 cups all purpose flour

3/4 cup graham cracker crumbs

1 tsp baking powder
1/4 tsp salt
2 king-sized Hershey's milk chocolate bars (if you want a more subtle chocolate flavor use regular sized chocolate bars; enough to fit)
1 1/2 cups marshmallow creme/fluff (7 1/2 oz jar)

Directions:

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

2. In a large bowl, cream together butter and sugar 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 at a low speed until combined.

3. Divide dough in half and press half of dough into an even layer on the bottom of the prepared pan. Place chocolate bars over dough. 2 king-sized Hershey’s bars should fit perfectly side by side, but break the chocolate (if necessary) to get it to fit in a single layer no more than 1/4 inch thick. Spread chocolate with marshmallow creme or fluff. Place remaining dough in a single layer on top of the fluff. This part can be tricky. I made little disks with the dough and placed them on top. Spread it around gently.

4. Bake for 30 to 35 minutes, until lightly browned. Cool completely before cutting into bars.

Makes 16 cookie bars.
