S'mores Bars

Happy Thanksgiving! 

So this is what I made for Thanksgiving 2012: this s'mores bars recipe. Man, they were good! But man, they were soooo rich! 

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
3 king-sized Hershey's milk chocolate bars 
1 1/2 cups marshmallow creme/fluff

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

In a large bowl, cream together butter and both sugars until light. Beat in egg and vanilla. In a small bowl, whisk together flour, graham cracker crumbs, baking powder, and salt. Add this to the butter mixture and mix at a low speed until it's all mixed together (we'll call this your "dough").

Cover the bottom of the pan with an even layer of your dough. Place chocolate bars over dough. Three 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 is a little tricky...we tried placing the dough in small globs on top of the marshmallow, then spreading the globs into each other. It sort of worked, especially once we decided to grease the spoon we were using). I'm not sure if we just did a bad job of splitting the dough in half, or if the recipe did not create enough dough, because we did not have enough dough to cover the top. Sooo, improvising, we sprinkled on some more graham crackers. 

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