Spread 1 tsp. of the peanut butter onto each of 9 of the graham squares. Top each with about 1 Tbsp. of the chopped cookies, 1 tsp. of the fudge sauce and 3 or 4 marshmallows.
Cover each with second graham square to make s'more. Place 4 or 5 of the s'mores on microwavable plate.
Microwave on HIGH 10 to 15 seconds or until marshmallows begin to melt. Repeat with the remaining s'mores. Serve warm.
