Creating Holiday Puppy Chow is straightforward if you follow these easy steps:

1. Prepare the Cereal: In a large bowl, measure out the Rice Chex cereal and set aside.
2. Melt the Mixture: In a microwave-safe bowl, combine the chocolate chips, peanut butter, and butter. Microwave in 30-second intervals, stirring in between, until melted and smooth.
3. Add Vanilla: Stir in the vanilla extract into the melted mixture until well combined.
4. Coat the Cereal: Pour the melted chocolate mixture over the Rice Chex cereal. Gently stir until all the cereal is evenly coated.
5. Add Powdered Sugar: Place the coated cereal in a large zip-top bag or bowl. Add the powdered sugar and shake or stir until all pieces are coated.
6. Cool: Spread the Puppy Chow onto a baking sheet lined with parchment paper to cool completely.
7. Serve or Store: Once cooled, serve immediately or store in an airtight container until you’re ready to enjoy.

These simple steps will guide you in creating this deliciously sweet treat without any fuss.
