Line a miniature muffin pan with muffin liners and set aside.
In a microwave safe bowl, combine chocolate chips with 1/2 teaspoon vegetable oil. Melt in the microwave using bursts of 20 seconds, stirring in between each burst for 15 seconds, until smooth and fully melted. Make sure to stir really well in between each bursts as it's easy to burn the chocolate.
Fill the bottom of the muffin liners with equal amounts melted milk chocolate. Tap the muffin pan a few times to get the chocolate to go in an even layer. Place in the fridge for 5–10 minutes.
While it's chilling, coarsely chop the candy cane bar and place in another microwave safe bowl. Add in the remaining 1/2 teaspoon vegetable oil and stir.
Again, melt in the microwave in bursts of 20 seconds, stirring for 15 seconds in between each burst.
Pour equal parts of the white peppermint chocolate over the milk chocolate. Tap the muffin tin a few times to get the chocolate in an even layer.
Allow to set.
