Add the oats, water and milk to the instant pot. Close the lid with vent in sealing position.

Once the instant pot beeps, let the pressure release naturally.
Add the honey, banana and walnuts to the cooked oats. Add milk to taste to adjust the consistency. Perfectly cooked oats are ready to enjoy.
Notes
Variation: Add the fruits and nuts of your choice to the cooked oats. You can also add cinnamon if you like when adding the ingredients to the instant pot in step 1.Pot-in-pot: If you are making a small quantity, you can do pot-in-pot (PIP). Add one cup water to the main pot. Place a trivet and a small bowl with the ingredients added on top of the trivet. Cook for 5 minutes on manual high pressure, otherwise the recipe remains the same. Overnight with Delay Timer: To cook oats overnight with delay timer, add the oats and water to the pot. Set the timer to the desired time such as 8 hours (Press manual/pressure cook, then press Timer and adjust to the desired time). The instant pot will start cooking at the set time. Once the pressure is released naturally, add milk and adjust oatmeal to the desired consistency.
