01 - Line a large baking sheet with parchment paper or a silicone baking mat to prevent sticking.
02 - In a large mixing bowl, combine Rice Chex cereal, mini pretzels, and popcorn. Mix gently to distribute evenly.
03 - Pour melted white chocolate over the cereal mixture. Gently toss and fold until all pieces are evenly coated.
04 - Add mini marshmallows, green chocolate candies, and white chocolate chips to the coated mixture. Toss gently to distribute without crushing delicate ingredients.
05 - Spread the mixture in an even layer on the prepared baking sheet. Immediately sprinkle rainbow sprinkles over the top before the chocolate begins to set.
06 - Allow the mix to sit at room temperature for 20-30 minutes until the chocolate hardens completely. Break into clusters and serve, or store in an airtight container for up to 5 days.
