When about to boil, reduce heat to medium-low and add the oats, cinnamon, and vanilla.
Cook, stirring often, until the oats are softened and the water is absorbed, about 4-6 minutes.
Stir in the chia seeds, milk, and fruit of choice, if using.
Cook for an additional 4-6 minutes or until the fruit is soft and the liquid is absorbed.
Remove from the heat. Cover and let sit for about 5 minutes.
Serve warm with any additional toppings and additional milk.
