Mash bananas in a small bowl.
Spray the inner pot of your pressure cooker/Instant Pot with cooking oil. Add milk, oats, mashed bananas, vanilla cinnamon, and sea salt and stir to combine.
Close Instant Pot and lock, turn air vent to "Sealing" and set manual pressure cooking to 3 minutes.
Allow to cook and once timer is up, allow the oatmeal to slow release for 5 minutes. When 5 minutes is up, quick release any other pressure and open the pot. Stir in brown sugar and maple as well as the pecans.
Allow to thicken for several minutes and then serve as desired. I loooooved mine with a touch of butter on top and some extra pecans!
