This simple twist on classic puppy chow combines the flavor of your favorite brownies and Chex cereal to create sweet, salty, and crunchy brownie puppy chow.
Food Safety Step: Preheat oven to 350 degrees F. Spread brownie mix out on a baking sheet and bake for 5 minutes. Allow brownie mix to cool completely before using.
In a microwave-safe bowl, add milk chocolate chips and peanut butter. Heat in the microwave for 1 minute, then stir. Continue to heat in the microwave for 30 second intervals until chocolate chips are soft. Using a whisk or a fork, stir chocolate and peanut butter until smooth.
Add Chex cereal to a 13 quart mixing bowl. Pour chocolate-peanut butter mixture on top and gently stir with a spatula until all Chex cereal is coated. Set bowl aside.
Add dry brownie mix to a Ziploc bag. Working in batches (about 1-2 cups at a time), add coated Chex cereal to bag with brownie mix, seal or twist the top of the bag closed, and then shake the bag until the Chex cereal is coated with brownie mix. Remove finished brownie puppy chow and spread out on prepared baking sheet. Repeat step until all the puppy chow is made. When finished, discard plastic bag and any dry brownie mix that remains inside.
Let brownie puppy chow cool completely before eating.
