If using, stir together the spiced sugar topping ingredients in a small bowl and set aside.
Whisk together the milk and chestnut praline syrup in a small saucepan and heat over medium-low heat until starting to steam and foam.
Remove from heat, and if desired, froth with a milk frother. Set aside.
Brew you coffee into a mug and top with the chestnut praline milk, foam and all. Top with whipped cream and/or spiced sugar topping if desired. Drink up!
Notes
You will have extra spiced sugar topping. Simply store in an airtight container at room temperature for up to 3 months.
