Begin by heating a non-stick skillet over medium-low heat. Slice a ripe banana and add it to the pan along with a sprinkle of brown sugar. Cook for about 3-5 minutes, stirring gently until the banana becomes golden and caramelized.

In a mixing bowl, combine rolled oats with the caramelized banana from the skillet. Pour in milk of your choice, add vanilla extract, ground cinnamon, and a pinch of salt. Stir thoroughly to combine.

Let the mixture sit at room temperature for about 5 minutes to allow the oats to absorb the milk evenly.

Transfer the mixture into an airtight container, sealing it tightly. Place it in the refrigerator and let it chill overnight, or for up to 48 hours.

When ready to serve, stir the oats. For a creamier texture, add a splash of milk or yogurt. Serve chilled, garnished with extra banana slices or toppings.
