01 - In a small saucepan, warm the milk over medium heat until steaming but not boiling. Whisk occasionally to prevent scorching.
02 - Stir the cinnamon, nutmeg, cloves, and sweetener into the warmed milk. Whisk vigorously to blend the spices evenly and create a light froth.
03 - Prepare two shots of espresso or strong coffee using an espresso machine or coffee maker.
04 - Pour one shot of espresso into each serving mug.
05 - Slowly pour the spiced, frothed milk over the espresso in each mug, dividing evenly between the two servings.
06 - Top with whipped cream if desired, dust with additional cinnamon or nutmeg, and garnish each mug with a cinnamon stick. Serve immediately while warm.
