In a gallon Hefty storage bag, combine the rice cereal, graham cracker bears, pretzels and peanuts. Shake well until well mixed.
In a small bowl, combine the melted butter, agave nectar and cinnamon with a whisk. Pour butter mixture over the cereal mixture inside the storage bag and shake well. Pour out of bag and onto a baking sheet.
Bake in the oven for 10 minutes, stirring once at 5 minutes. Remove from oven and allow to cool. Split the snack mix into two Hefty quart storage bags, breaking up the snack mix with your hands through the plastic. Add the white chocolate and dried cranberries to the bags and shake well.
Eat immediately or store in Hefty freezer bags to enjoy later.
