Heat Tazo concentrate in a small saucepan over medium heat until hot (a little too hot to drink is okay; it will cool to perfect drinking temperature while you froth the milk).
Pour concentrate into mug. Return saucepan to stove and add milk, heating until warm.
Quickly whisk the milk for approximately 1-2 minutes or until frothy. Add milk to the concentrate in the mug. If there are milk bubbles left over in your saucepan, use a spoon to gently scoop and place the foam on the top of your latte.
Garnish with cinnamon if desired. Snuggle up somewhere cozy, sip, and enjoy.
