Makes 16 2" squares

1/2 cup unsalted butter, room temperature
1/2 cup sugar
1 tsp unsulphured molasses
1 large egg
1 tsp vanilla extract
1 1/3 cups all purpose flour
1 cup graham cracker crumbs
(from about 8-9 graham cracker sheets broken down in a food processor)
1 tsp baking powder
1/4 tsp salt
2 king-sized or 4 regular-sized milk chocolate bars
1 1/2 cups marshmallow fluff (Recipe Below)

XIAOLU'S NOTES: You can certainly use store-bought marshmallow fluff but the homemade recipe below is very simple, cheap, and superior in flavor. I made cracker crumbs with a plastic bag and rolling pin/wine bottle. Lastly, I used a 9-inch instead of 8-inch pan, so my bars turned out thinner and less gooey than the original.

Preheat oven to 350 degrees F. Line an 8-inch square baking pan with parchment paper, including the sides. (You can also just grease the pan.) In a small bowl, whisk together flour, 3/4 cup graham cracker crumbs, baking powder, and salt.

In a large bowl, cream together butter and sugar until light. Beat in egg, molasses, and vanilla. Add the dry ingredients and mix at a low speed until combined. Divide dough in half and press one half into an even layer on the bottom of the prepared pan.

Place chocolate bars over dough, breaking the chocolate (if needed) to get it to fit in a single layer no more than 1/4 inch thick. Spread marshmallow creme or fluff on top of the chocolate. Combine the remaining dough with the reserved 1/4 cup of graham cracker crumbs. Then flatten the dough into small pieces and spread them in a single layer on top of the fluff. There will probably be crumbs left over. Simply sprinkle these over the top, especially over any sections with marshmallow fluff still peaking out. Bake for 30 to 35 minutes, until lightly browned. Cool completely before cutting into bars.

NOTE: This is more than you need for the s'more bars, but extra fluff can easily be refrigerated for up to 1 week OR frozen for later use. Just make sure to defrost it and stir well with a spoon before using.
