Measure cereal, hemp and nuts and mix together in a large bowl, set aside.
Pour powered sugar and protein powder into a large resealable zip-lock bag.
In a large saucepan over low-medium heat add peanut butter, chocolate chips and coconut oil. Stir continuously until chocolate chips have melted and the mixture is smooth.
Pour cereal mixture into pot with melted chocolate mixture and toss until evenly coated.
Carefully pour coated cereal mixture into the bag with the powdered sugar and protein powder. Seal bag; shake until well coated. Spread on parchment paper to cool completely. Make sure you let it cool for a while before putting it in a container, otherwise your mix will get soggy.
Store in an airtight container in the refrigerator. Keeping it in the fridge will keep it fresh and crunchy!
