• Line 9x13-inch baking pan with foil and spray with cooking spray. Set aside.

Prep:

• Make a foil "sling" in a 9x13-inch baking dish, and spray with non-stick spray.
• Coarsely chop the graham crackers (not too finely), set aside.
• Measure 2-1/2 cups of milk chocolate chips, set aside.
• Measure 1-1/2 cups milk chocolate chips, set aside.
• Measure 5 cups of Rice Krispie cereal into a very large bowl.
• In large bowl, melt marshmallows and butter in microwave.

  Do this by heating for 1 minute and 30 seconds, then stir it and cook another 30 seconds, until it is all melted and smooth.
• Pour the melted marshmallow mixture into the rice krispies and 1 1/2 cups of roughly crushed graham crackers. Then stir in 1 cup of chocolate chips.
• Spread evenly into prepared baking dish. Butter your hands, and press the mixture evenly into the pan.
• Let cool for at least 15 minutes, ideally 30 minutes.

For the topping:

• In a medium bowl, melt the 2 cups of chocolate chips in microwave for about 1 minute, until smooth and melted. Stir vigorously, and microwave in 15 second intervals until it's completely smooth and melted.

  Spread evenly over rice krispies; spread with an off-set spatula.
• Sprinkle with remaining graham crackers and press lightly, with a flat spatula for ease, into the chocolate so they stick.
• Chill another 15 to 30 minutes, then enjoy!
