1. In a small saucepan, combine water and cinnamon sticks (or ground cinnamon). Cover and bring to a boil, then reduce heat and simmer for about one minute.

2. Turn off heat and add black tea bags or loose tea (using a strainer or French press), cover, and steep for 5 to 7 minutes. Avoid over-steeping to prevent bitterness.

3. Remove tea bags or strain loose tea and cinnamon sticks.

4. Add milk, vanilla extract, and sweetener of choice to the saucepan. Warm gently over medium heat until steaming but not boiling, stirring lightly to blend flavors.

5. Froth the milk mixture for a creamier texture before serving. Pour into mugs and garnish with a sprinkle of ground cinnamon or an extra cinnamon stick if desired.
