Pour the entire box of Chex cereal into your large mixing bowl
Put the chocolate chips in your small mixing bowl and microwave on 30 second increments until half way melted
Once the chocolate is half way melted, add the peanut butter and continue to microwave until both are full melted.
Stir the chocolate and peanut butter together and pour over your bowl of Chex cereal
Mix together until the cereal is completely covered in chocolate
Put half of your fudge brownie mix into a gallon size ziplock bag
In small increments, pour some of your chex cereal into the bag and shake it up.
Scoop the cereal out and place on a sheet pan
Repeat this step of pouring small amounts of the cereal into the ziplock bag and shaking it, until all the cereal has been tossed in the powder
Leave the cereal on your baking sheet until it is completely dry (about an hour) and serve!
