Cover baking sheet with parchment paper.
Unwrap peppermint candy canes and place in ziplock bag. Lightly crush with a rolling pin or mallet. Pour into bowl.
Combine chocolate chips and coconut oil in a microwave safe bowl. Melt in 30 second increments. Stir between rounds until smooth.
Dip marshmallows in chocolate, then in crushed peppermint candy canes. Place peppermint side down on parchment paper.
Refrigerate until chocolate is solid.
It may help to let chocolate partially solidify before dipping the marshmallows in peppermint. Don't let it get too hard.
