01 - Line a large baking sheet with parchment paper to prevent sticking.
02 - In a large mixing bowl, add the rice cereal squares, corn cereal squares, small pretzel twists, salted peanuts, cheese crackers, mini marshmallows, and chocolate-coated candies. Toss gently to mix evenly.
03 - Place white chocolate chips (and coconut oil or vegetable shortening, if using) in a microwave-safe bowl. Microwave in 30-second intervals, stirring after each, until smooth and fully melted.
04 - Pour the melted white chocolate over the dry snack mixture. Using a spatula, quickly and gently fold until all components are evenly coated.
05 - Transfer the coated mixture onto the prepared baking sheet, spreading into a single even layer.
06 - Let the mixture cool at room temperature for approximately 20 minutes, or until the coating has fully set.
07 - Break the set snack mix into clusters and transfer to an airtight container. Store at room temperature for up to 1 week.
