Begin by setting your coffee to brew at double strength. This is crucial as the ice will dilute the coffee.
While brewing, place the cinnamon stick(s) in your serving glass.
Once brewed, immediately pour the hot coffee over the ice and cinnamon stick(s) in the glass.
Stir gently to ensure the flavors meld.
For added sweetness, introduce the cinnamon-infused simple syrup to taste and stir.
