In the insert of the Instant Pot, add all of the ingredients. Stir to mix them together and to roughly coat the apples in the cinnamon and brown sugar.
Place the lid on the Instant Pot and turn the valve to SEALING. Press MANUAL or PRESSURE COOK on HIGH PRESSURE and set timer for 5 minutes.
When the timer is finished, let the Instant Pot sit for 10 minutes and do a NATURAL RELEASE, then move the valve to VENTING to quick release any of the remaining pressure.
Remove the lid and stir, then serve warm.
Notes
Golden Delicious apples are also great for this recipe.Total time does not account for the time that it takes to come to pressure and the natural release of pressure after it is done cooking.
