Peruvian Avena con Leche (Oatmeal with Milk)

Combine the rolled oats, whole milk, granulated sugar, and cinnamon stick in a medium saucepan.

Bring the mixture to a gentle boil over medium heat, stirring occasionally to prevent sticking.

Once boiling, reduce the heat to low and simmer for 10-12 minutes, stirring frequently, until the oats are tender and the mixture has thickened to your desired consistency.

Remove the saucepan from the heat and carefully remove the cinnamon stick.

Stir in the vanilla extract.

Ladle the avena con leche into individual bowls and sprinkle with ground cinnamon before serving warm.
