Core apples and slice into eighths. Leave apple peels on. I used an apple corer which makes the coring process so much easier!
6 pounds apples
Add apples, apple cider, brown sugar, and cinnamon to Instant Pot.
½ cup brown sugar, ½ cup apple cider, 2 teaspoon cinnamon
Place lid on instant pot and set to high pressure for 20 minutes cooking time.
Once the cooking process has completed, allow natural pressure release for 15 minutes. Carefully release any remaining pressure and remove lid.
Allow to cool for 15 minutes. Use an immersion blender to blend the cooked apple mixture until smooth. As an alternative, you can use a regular blender or food processor after allowing the cooked apples to cool for 30 minutes. It's not necessary to let the apple butter come to room temperature.
Set instant pot to sauté function, the lowest setting so there is no spatter, and allow to cook for another 30 to 60 minutes until the desired consistency. Stir occasionally with a wooden spoon so that the mixture doesn't stick to the bottom of the pot and burn. If, even at the lowest setting you're experiencing some splashing, cover the top of the instant pot with a splatter guard.
To test for doneness, remove a spoonful from the pot and if it's done the butter will stay mounded on the spoon. Another method is to spoon a small amount on to a plate. If a rim of liquid doesn't separate, it's ready.
Store in mason jars or airtight containers and refrigerate or freeze.
