Warm milk infused with Mexican cinnamon is a soothing, traditional bedtime drink. This family-friendly, fresh beverage is a comforting, simple way to wind down the evening.
In a medium saucepan, pour in the whole milk and add the Mexican cinnamon sticks.
Set the pan over medium-low heat and slowly bring the milk to a gentle simmer, stirring occasionally to prevent scorching.
Once the milk is steaming and just starting to bubble around the edges (do not let it boil), lower the heat and stir in the sugar until completely dissolved.
Let the milk gently simmer for 5–7 minutes so the cinnamon fully infuses and the fragrance deepens; stir gently to distribute the cinnamon flavor.
Remove from heat, discard the cinnamon sticks, and pour the leche con canela into mugs. Serve warm.
