This popular snack mix is also know as Muddy Buddies. This version is flavored with a hint of cinnamon.
Place cereal in large bowl. Set aside. Microwave chocolate, marshmallow creme, peanut butter and 1 teaspoon of the cinnamon in medium microwavable bowl on HIGH 1 minute; stir. Microwave 20 to 30 seconds longer or until mixture can be stirred smooth. Stir in vanilla.
