My dear, sweet husband is always wanting to go camping. Don’t get me wrong, I love a little over-nighter in a tent but that is about as wild as it got for us growing up in a family of all girls. He was quite sad when I broke the news to him that my very pregnant body, at the time, just couldn’t handle sleeping on the ground and dealing with a toddler in a tent. While he was at work, my little buddy and I decided to set up an indoor campsite to surprise dad when he got home. He may not have been as excited as he would have been if we had really camped, but these s’mores bars sure eased his pain. I enjoyed one too many of these yummy treats, slept in my own bed and listened to my boys laugh out in the living room. That is my kind of camping!
Preheat oven to 350°F. Grease an 8-inch square baking pan.
In a large bowl, cream together butter, brown sugar, and sugar until light and fluffy.
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 (3 king-sized Hershey 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 marshmallow creme over chocolate layer. Place remaining dough in a single layer on top of the marshmallow (most easily achieved by flattening the dough into small, flat shingles and laying them together).
Bake for 30 to 35 minutes, until lightly browned. Cool completely before cutting into bars.
