01 - Line a large baking sheet with parchment paper to prevent sticking.
02 - In a large mixing bowl, mix together crispy rice cereal, corn cereal, pretzels, salted peanuts, cheese crackers, mini marshmallows, and chocolate-coated candies until evenly distributed.
03 - Place white chocolate chips and optional coconut oil or vegetable shortening into 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 snack mixture. Use a spatula to quickly and gently fold until all components are evenly coated.
05 - Transfer the coated mix to the prepared baking sheet, spreading into a single even layer. Allow mixture to rest at room temperature for about 20 minutes or until chocolate is set.
06 - Once set, break the snack mix into chunks. Store in an airtight container for up to one week.
