S'more Cookie Bars

Saturday we went to a birthday party where everyone brought side dishes or dessert. This was one of the desserts served. OH MY!!!!!! It is delicious :) It's AWESOME! I can't wait to make it. Thanks, Debbie!

1/2 c. butter, room temperature
1/4 c. brown sugar
1/2 c. sugar
1 large egg
1 tsp. vanilla extract
1 1/3 c. flour
3/4 c. graham cracker crumbs (approximately 7 full graham crackers)
1 tsp baking powder
1/4 tsp salt
2 super sized (5 oz.) dark chocolate bars (e.g. Hershey's)*
1 1/2 c. marshmallow cream/fluff

Preheat oven to 350 degrees. Grease an 8 inch square baking pan. 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. 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 the marshmallow fluff over the chocolate. Place remaining dough in a single layer on top of the fluff (most easily done by putting the dough in a gallon size ziplock bag or between plastic wrap. Use your palms or a rolling pin to flatten it out and then use scissors to cut down both long sides of the bag, so it will open up book-style. Place the bag, dough side down, on the fluff. From there peel the bag up and spread the dough where it is uneven.) Bake for 30 to 35 minutes, until lightly browned. Cool completely before cutting into bars.

*Debbie's Notes - I made this amazing dessert for the first time this past Sat for a BBQ birthday party after first having it at my sister's house. I did not have chocolate bars on hand, so instead used semi sweet Ghirardeli chocolate chips. If you use the choco chips, make sure to press them into the dough so that spreading the marshmallow cream over it will be a little less challenging. I think it turned out great, but then again I am a bit biased to Ghirardeli.
