In a large bowl, gently mix together the Chex mix, popcorn, pretzels, and peanuts.
In a separate microwave-safe bowl or using a double boiler, melt the white chocolate chips with the coconut oil until smooth and creamy. Heat slowly, stirring often, to prevent scorching.
Pour the melted white chocolate mixture over the dry ingredients in the large bowl. Use a rubber spatula or wooden spoon to stir everything gently until all pieces are beautifully coated.
Fold in your favorite Christmas sprinkles. For best results, add delicate candy mix-ins after the chocolate has slightly cooled to prevent melting.
Spread the coated mixture evenly onto a baking sheet lined with parchment paper. Place it in the refrigerator for at least 30 minutes, or until the chocolate is completely set and firm.
Once firm, break the festive chow into delicious, snackable pieces. Store in an airtight container and enjoy!
