Step 1

Brew espresso or strong coffee as desired.

Step 2

Pour milk into a mason jar with chocolate syrup and peppermint extract. Microwave for 1 ½ minutes. Depending on your microwave, you may need to continue heating in 30-second increments up to another minute. You want the milk hot, but not boiling.

Step 3

Carefully remove the jar of milk from the microwave; use a towel or potholder as needed - it will be hot. Place the lid on the jar and shake vigorously for 30 seconds to 1 minute. See notes below for additional frothing methods.

Step 4

Continuing to use a towel or potholder, remove the lid carefully, being aware of any pressure that may have built up in the jar.

Step 5

If desired, drizzle chocolate syrup in the mug you'll be using. Add the espresso and pour in the chocolate milk mixture, topping with any foam that remains in the jar. Serve immediately with whipped cream and additional chocolate drizzle or crushed peppermint candies, if desired.
