01 - Line a large baking sheet with parchment paper and set aside.
02 - In a large mixing bowl, mix together the crispy rice cereal squares, corn cereal squares, pretzels, salted peanuts, cheese crackers, mini marshmallows, and chocolate-coated candies until well distributed.
03 - In a microwave-safe bowl, combine white chocolate chips and coconut oil or vegetable shortening if using. Microwave in 30-second intervals, stirring after each burst, until the chocolate is completely smooth and melted.
04 - Immediately pour the melted white chocolate over the snack mixture. Quickly and gently fold the mixture with a spatula until all pieces are evenly coated.
05 - Transfer the coated mix to the prepared baking sheet, spreading into an even, single layer. Let cool at room temperature for about 20 minutes or until the coating is fully set.
06 - Once set, break the mixture into chunky pieces. Store in an airtight container at room temperature for up to 1 week.
