Trash - Muddie Buddies

Pour the Chex cereal into a very large mixing bowl and set aside. In a separate microwave-safe bowl, combine the butter, chocolate chips, peanut butter, and vanilla. Microwave for about 30 seconds at a time, stirring between intervals, until the mixture is smooth and easy to stir.

Pour the melted chocolate mixture over the cereal and gently stir until all the cereal pieces are evenly coated. Transfer the coated cereal mixture into a large 2-gallon resealable bag. Add the powdered sugar, seal the bag, and shake well until the cereal is fully coated.

Place the mixture in the refrigerator until chilled and ready to serve.
