Peanut Butter S’mores Cookie Bars

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

In a large mixing bowl, beat the butter and sugar until well blended. Add egg and vanilla, beat well. Set aside.

In a medium sized bowl stir together graham cracker crumbs, flour, baking powder and salt. Add the flour mixture into the butter mixture and mix until well combined. Press half of the dough into the prepared pan. Bake 15 minutes.

Remove pan from oven. Sprinkle chocolate chips over the baked layer, drop peanut butter by spoons full over the chocolate chips, then use a toothpick to swirl everything around so the bottom cookie layer is evenly covered. Sprinkle with marshmallows and scatter the remaining dough over the marshmallows, forming the top layer.

Bake for an additional 10 to 15 minutes or just until lightly browned. Remove pan from oven and cool completely in the pan on a wire rack. Cut into bars.
