Bring the water to a boil.
Place the chai tea bags in a mug and add the water. Let steep for 3 to 5 minutes (or according to the directions on the package of tea). I like to steep mine for at least 5 minutes for a stronger chai flavor.
While the tea is steeping, heat the milk in a small saucepan over low heat until hot (do not boil).
Squeeze out the tea bags into your mug (be careful and use a spoon - the bags will be hot). Add the maple syrup and vanilla to the tea; stir to combine.
Remove the milk from the heat and carefully whisk, using a quick left-to-right motion, until the milk is frothy and foamy.
Pour the milk into the mug with the tea. Spoon any foam that is left behind in the pan onto the top of your latte.
Sprinkle with cinnamon and enjoy!
