In a large bowl crush graham crackers and pour in rice crispy treats and chocolate chips. Mix together and set aside.
Brown the butter in a small saucepan. This should take 1-2 minutes.
Line a cookie sheet with foil or parchment paper and spread out marshmallows. Broil the marshmallows until puffed and golden brown. It usually takes about a minute unless you are a fan of charred marshmallows. Watch these VERY carefully, they can get burnt very very fast and everyones oven is different.
Pour browned butter into the cereal mixture and mix, then add in the marshmallows using a rubber spatula.
Press the mixture into a 9X13 inch pan and let cool. Enjoy!
