Bring 2 cups of water to a boil in a medium saucepan.

Add 2 tablespoons chai tea leaves or 2 chai tea bags to the boiling water and steep for 5 minutes.

While the tea is steeping, heat 1 cup of milk in another saucepan over medium heat until warm.

Strain the chai tea into a mixing glass, discarding the leaves or tea bags.

Add 2 ounces spiced rum, 1 tablespoon honey, 1/4 teaspoon ground cinnamon, and 1/4 teaspoon ground ginger to the strained chai.

If desired, add ice to a shaker, pour in the mixture, and shake for a few seconds to chill.

Pour the warm milk into the mixture and stir gently to combine.

Pour the chai cocktail into serving glasses and garnish with a sprinkle of cinnamon, if desired.
