S'more Bars

I recently made these for a family reunion party - I adapted it a little bit

The original recipe :Lovin' From the Oven

My Version:

S'more Bars

1 cup butter, room temperature
1/2 cup brown sugar
1 cup sugar
2 large egg
2 tsp vanilla extract
2 2/3 cups all purpose flour
1 1/4 cup graham cracker crumbs
2 tsp baking powder
1/2 tsp salt
1 12oz bag of chocolate chips
2 cups marshmallow creme/fluff (not melted marshmallows)

Directions:

1. Preheat oven to 350°F. Grease an 10x 13 in baking pan.
2. In a large bowl, cream together butter and sugar until light. 
3. Beat in egg and vanilla. In a small bowl, whisk together flour, graham cracker crumbs, baking powder and salt. 
4. Add to butter mixture and mix at a low speed until combined.
5. Divide dough in half and press half of dough into an even layer on the bottom of the prepared pan. Place chocolate chips over dough 
6. Spread chocolate with marshmallow creme or fluff. 
7. Place remaining dough in a single layer on top of the fluff (most easily achieved by flattening the dough into small shingles and laying them together).
8. Bake for 30 to 35 minutes, until lightly browned. Cool completely before cutting into bars.
