1. Grease a 8x8 pan and set aside. In a large pan, melt butter over medium heat. Stir in 2 1/2 cups mini marshmallows. Stir until marshmallows are melted and smooth. Stir in the Golden Grahams cereal. Press mixture into prepared pan.

2. Place Hershey's candy bars on top of the Golden Grahams treat and gently press them down. Sprinkle the remaining marshmallows evenly over the chocolate bars. Place under the broiler for about 2 minutes, or until marshmallows are slightly golden brown. Watch them closely so you don't burn the marshmallows. Let the bars cool completely. Cut into squares and serve.
