Heat a non-stick skillet over medium-low heat, then add sliced ripe banana and brown sugar. Cook for 2-3 minutes until golden brown and syrupy.

In a mixing bowl, combine the rolled oats, caramelized banana, milk, vanilla extract, cinnamon, and sea salt. Stir to coat the oats.

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

Transfer the mixture into an airtight container, seal tightly, and refrigerate overnight.

In the morning, stir the oats, and add your favorite toppings before enjoying.
