In a medium bowl, combine rolled oats, coconut milk, Greek yogurt, shredded unsweetened coconut, maple syrup, vanilla extract, ground cinnamon, and salt. Stir vigorously to ensure everything blends smoothly, creating a creamy mixture full of tropical flavor.

Gently fold in sliced bananas, if using, ensuring they are evenly distributed.

Divide the prepared mixture into two jars or containers with lids, sealing tightly.

Refrigerate overnight, or for a minimum of four hours.

Once ready, remove from the fridge, stir, and top with fresh whipped cream and a sprinkle of shredded coconut if desired.
