In a large bowl, combine the rice krispies, Golden Grahams cereal, marshmallow bits, and chocolate chips.
Melt butter in a large saucepan over medium-hight heat. Turn down the heat to the lowest setting and add the regular sized marshmallows.
Stir constantly until almost totally melted, then add the vanilla extract. Continuing stirring until the marshmallows are all melted, then pour into the rice krispie and graham mixture. Stir lightly to combine.
Pour into a lightly greased 9×9 pan. Grease hands with non-stick spray and lightly press into the pan to even out. Allow to cool and set for about 15-20 minutes! Top with extra marshmallows, graham cereal and drizzle with chocolate sauce.
