Using your Ninja Coffee Bar® System, make coffee according to package instructions.
While the coffee is brewing, place chocolate and milk into a glass measuring cup or bowl and microwave for 30-60 seconds. Stir to melt chocolate. Once chocolate is melted through, add in peppermint syrup.
Once the coffee is done and the milk mixture is ready, add both together in a glass cup. Stir to combine.
Top with whipped cream and peppermint sticks.
Serve immediately and enjoy!
