01 - Line a large baking sheet with parchment paper to prevent sticking.
02 - In a large mixing bowl, add crispy rice cereal squares, corn cereal squares, pretzel twists, salted peanuts, bite-sized cheese crackers, mini chocolate-coated candies, and mini marshmallows. Gently mix to distribute evenly.
03 - Place white chocolate chips and coconut oil or vegetable shortening (if using) in a microwave-safe bowl. Heat in 30-second intervals, stirring after each burst, until fully melted and smooth.
04 - Pour melted white chocolate mixture over the dry ingredients. Using a spatula, quickly and gently fold to ensure uniform coating across all components.
05 - Transfer the coated mixture to the lined baking sheet and spread into an even layer. Allow to cool at room temperature for approximately 20 minutes, or until the chocolate is set.
06 - Break the mixture into chunks and transfer to an airtight container. Store at room temperature for up to 1 week.
