Avena (Oatmeal)
1 cup old-fashioned oatmeal
6 cups milk
1 cinnamon stick
1 teaspoon vanilla extract, optional
sugar to taste
In a medium saucepan, place the oats, cinnamon stick and milk over medium-low heat and cook, stirring constantly, until the oatmeal is thick, about 10 minutes. Add sugar, to taste, and set the oatmeal aside to cool slightly.
Transfer the oatmeal to a container, add vanilla extract, and refrigerate it for at least 2 hours or overnight. Strain the liquid and serve cold. Add more milk if you want it thinner.
