Set a medium saucepan over medium heat. Add milk, half & half, cocoa mix, peppermint bark, crushed candy cane, peppermint extract, and salt. Bring to a low simmer, whisking frequently. Allow the cocoa to simmer for 10 minutes before removing from the heat.
Divide between mugs, garnish as desired.
Notes
-If you don't want to make the homemade hot cocoa mix, you can swap it out for your favorite PLAIN cocoa mix. Add a 1/4 tsp. vanilla extract along with the peppermint extract.
