In a medium microwavable bowl, microwave white chocolate or vanilla almond bark with the peppermint baking chips in 30 second intervals, stirring in between, until completely melted.
Pour over Chex Mix and toss until evenly coated. Add the crushed candy cane and stir.
Add powdered sugar to a zip lock bag and add the Chex Mix to the bag. Seal and gently toss and shake until fully covered.
Lay out on parchment paper to cool and set. Sprinkle additional crushed candy cane immediately if desired.
Note: I specifically made this recipe to have a subtle peppermint flavor that my whole family would enjoy. If you want a stronger flavor, you can adjust the melted chocolate ratio, such as 3/4 cup white chocolate and 2/3 cup peppermint chips.
You could also add additional crushed candy cane before the powdered sugar.
