Step 1: Melt the Mixture
In a medium saucepan over low heat, combine the semi-sweet chocolate chips, creamy peanut butter, and salted butter. Stir continuously until the mixture is completely melted and smooth. If you’re using vanilla extract, add it in once everything is melted, and stir to combine.
Step 2: Prepare the Cereal
In a large mixing bowl, add your chosen Chex cereal. Pour the melted chocolate mixture over the cereal and gently stir until all the pieces are evenly coated. Be careful not to break the cereal while mixing!
Step 3: Add the Powdered Sugar
Once the cereal is well-coated, it’s time for the powdered sugar! Place about 1 1/2 cups of powdered sugar into a large resealable plastic bag. Add the chocolate-coated cereal to the bag, seal it tightly, and shake until all the cereal is coated in powdered sugar. If you prefer a sweeter treat, feel free to add more powdered sugar.
Step 4: Cool and Serve
Spread the Puppy Chow onto a baking sheet lined with parchment paper to cool completely. Once cooled, it’s ready to be served! You can store it in an airtight container for later enjoyment or enjoy it right away.
