Andrea's Puppy Chow

9 cups of Chex Cereal (Rice or Corn)
1 cup chocolate chips
1/2 cup peanut butter
1 1/2 cup powdered sugar
1/4 cup butter

Melt the butter, peanut butter, and chocolate chips together. (in the microwave is fine) Pour the melted mixture over the Chex cereal, coating the cereal. Sprinkle the powdered sugar over the covered cereal. Transfering the cereal to a zip lock baggy or a paper bag with the powdered sugar and shaking it to coat works really well.
