Sweet and Crunchy Popcorn Snack Mix

Step 1
Line a large baking sheet with waxed paper.

Step 2
Combine crispy corn and rice cereal, honey graham cereal, peanut butter corn puff cereal, popcorn, chocolate pieces, and peanuts in a large bowl.

Step 3
Melt butter in a large saucepan over medium heat; whisk in flour until smooth, 2 to 3 minutes. Add brown sugar and corn syrup; bring to a boil, stirring occasionally, until sugar is dissolved, about 1 minute. Stir peanut butter into sugar mixture until creamy, about 3 minutes; pour over cereal mixture and gently toss until coated.

Step 4
Spread cereal mixture over prepared baking sheet and allow to cool, about 30 minutes. Once cooled, break mixture into chunks and store in an airtight container.
