Get your ingredients and dishes ready to go right away. Measure out your 7 cups rice krispies and place in a large bowl. Grind up your graham crackers in a food processor, or blender or any other way you would like to grind them up.
Grease a 9x13 glass baking dish well with non-stick spray. Set aside.
In a large pot, put some butter over medium-high heat, and partially melt butter. Once butter is slightly melted, add the entire bag of marshmallows to the pot.
Stir frequently, melting the marshmallows with the butter. Once marshmallows are almost fully melted, add in the chocolate chips and stir constantly until they are JUST melted.
Remove from heat immediately, and stir in the rice krispies cereal.
Spray your hands with non-stick spray, and using a spoon and your hands, lay out the cereal mixture into the baking dish and flatten out using your sprayed hands (make sure hands are clean prior to this).
Before the treats set up, sprinkle (or bury) the top with ground up graham crackers.
Allow to set completely before cutting into squares. Consume within a few days.
