Pour 9 cups of Rice Chex into a large mixing bowl and set aside.
In a microwave-safe bowl, combine white chocolate chips and caramel bits. Microwave in 30-second bursts, stirring between each interval until melted and smooth.
Stir in 1 teaspoon of vanilla extract along with a pinch of salt to the melted mixture.
Pour the warm caramel mixture over the Chex and stir gently to coat evenly without breaking any pieces.
In a small bowl, mix together apple pie spice, powdered sugar, and granulated sugar.
Sprinkle the sugar mixture over the coated cereal while tossing to ensure everything is evenly covered. Fold in crushed dried apple chips before spreading the mixture on parchment paper to cool completely before serving.
