Begin by measuring 6 cups of Rice Chex cereal, carefully pouring it into a large mixing bowl. Set aside.

In a microwave-safe bowl, combine 1 cup of white chocolate chips, 2 tablespoons of unsalted butter, and 2 tablespoons of orange zest. Microwave in 20-second intervals, stirring, until melted and smooth.

Once the chocolate mixture is silky, add 1 tablespoon of orange extract. Stir well to combine.

Pour the melted mixture over the Rice Chex cereal and gently fold until each piece is evenly coated.

In a large zip-top bag, add 1.5 cups of powdered sugar, 1 box of instant vanilla pudding mix, and 1 teaspoon of salt. Seal and shake to mix.

Transfer the coated cereal mixture into the bag with the powdered sugar mixture and shake until well-coated.

Spread the mixture onto a parchment-lined baking sheet to cool for about 10 minutes.
