Brew your coffee slightly stronger than you normally would, as the ice will dilute it. If using hot coffee, allow it to cool to room temperature first to prevent all your ice from melting immediately.
Add maple syrup to your glass and pour in 2 tablespoons of the coffee. Stir until the syrup is completely dissolved – this creates a concentrate that mixes more easily.
Add the pinch of salt and vanilla (if using) and stir to incorporate. These subtle additions enhance the maple and coffee flavors without being detectable on their own.
Fill your glass with ice cubes, leaving about an inch of space at the top for the milk.
Pour the remaining coffee over the ice, allowing it to chill as it flows through the cubes.
Add your milk or cream slowly, creating a beautiful layered effect if desired, or stir immediately for a uniform color.
Taste and adjust the sweetness if needed by adding a bit more maple syrup. The flavor should be balanced, with the maple complementing rather than overpowering the coffee.
Garnish with a light dusting of cinnamon or cocoa powder if desired and serve immediately.
