Place the apples into the Instant Pot, and then add the rest of the ingredients and stir gently to coat the apples.
Cover the Instant Pot with the lid and make sure the pressure valve is set to sealed.
Cook on manual pressure for 10 minutes.
Once the timer goes off, let the pressure naturally release for 15 minutes, and then flip the pressure valve to do a quick release to release the rest of the pressure.
Using an immersion blender, blend the apples so that they make a smooth consistency.
Turn on the saute function of the Instant Pot (to the lower heat/“ - ” option) and saute for 20-30 minutes to thicken the apple butter. Make sure to stir constantly to make sure it does not burn.
Once it has thickened, allow the apple butter to cool. It will continue to thicken as it cools.
Serve or store.
Notes
The apple butter will thicken as you saute it. If it is still not to your preferred consistency, you can add 1/2 tablespoon of cornstarch to thicken it up. It will also thicken up in the refrigerator.
For a well-rounded flavor, it's best to use a mix of sweet and tart apple varieties. Fuji, Honeycrisp, and Granny Smith are excellent choices.
When stored in an airtight container in the refrigerator, it can last up to two weeks. For longer storage, you can freeze it for up to a year.
Peeling is optional. If you prefer a smoother texture, peel the apples. If you're okay with a more rustic feel, keep the skins on.
You can add a splash of apple cider for an extra kick.
