01 - Line a large baking sheet with parchment paper to prevent sticking.
02 - Combine crispy rice cereal, corn cereal, small pretzel twists, salted peanuts, cheese crackers, mini marshmallows, and chocolate-coated candies in a large mixing bowl.
03 - Place white chocolate chips and coconut oil (if using) in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until fully melted and smooth.
04 - Pour the melted white chocolate over the dry mixture. Quickly fold with a spatula until all components are evenly coated.
05 - Transfer the coated snack mix onto the prepared baking sheet and spread into a single layer.
06 - Let the mixture cool at room temperature for about 20 minutes or until the coating has set completely. Break into chunks once set.
07 - Store in an airtight container at room temperature for up to one week.
