Line a baking sheet with parchment paper and set aside.
In a large mixing bowl, mix together the popcorn, cereal, pretzels, chocolate candy, and cashews.
Spread the mixture onto the baking sheet in an even layer.
Microwave the white chocolate in 10 to 20 second increments, stirring between cycles, until completely melted and smooth. Mix the coconut oil into the white chocolate.
Drizzle the melted white chocolate over the snack mix.
Generously sprinkle the nonpareils over the snack mix.
Use a spoon or spatula to gently mix the white chocolate and sprinkles into the snack mix, making sure to coat the snack mix as thoroughly as possible. Spread into an even layer.
Allow the mixture to sit uncovered until the chocolate has set and dried.
Spoon the snack mix into a large serving bowl or package in individual servings.
