Add the oats and the plant milk or water to the Instant Pot and stir.
Place the lid on your Instant Pot, set the valve to the "sealing" position, press the "pressure cook" or "manual" button, and set the pressure to high. Then cook for 2 minutes.
Natural release for 10 minutes and then carefully move the valve to the "venting" position and let the pressure release completely.
Remove the lid and serve your Instant Pot oatmeal immediately with your favorite toppings. I used sliced banana, vegan condensed milk, cacao nibs, and peanut butter.
Keep the leftovers in an airtight container in the fridge for up to 1 week or in the freezer for up to 1 month.
