Combine all ingredients in the pressure cooker pot.
Set cook time to 3 minutes for chewier oats, 5 minutes for creamier oats.
Do a quick pressure release.
Notes
Notes: If you want to cook your oatmeal overnight but your slow cooker doesn’t have a delay function, you can plug it in to a timer – like you would use to automatically turn on holiday lights – to make it kick on during the night.
