Peel and core the apples, but leave them whole. Place the whole apples in the Instant Pot.
3 pounds apples
Pour the apple cider vinegar and lemon juice over the apples.
1/4 cup apple cider vinegar, juice from 1/2 lemon
Sprinkle the granulated sugar, brown sugar, cinnamon, nutmeg and cloves over the top. Do not add water.
3/4 cup granulated sugar, 1/2 cup brown sugar, 1 tbsp ground cinnamon, 1/2 tsp ground nutmeg, 1/4 tsp ground cloves
Secure the lid and set the steam-release valve to Sealing. Cook on High Pressure for 8 minutes.
When the cooking time is complete, allow the pressure to release naturally for 10 minutes. Carefully release the remaining pressure.
Remove the lid. The apples should be extremely soft and mostly broken down. Use a potato masher to mash the apples and cooking liquid until smooth.
Set the Instant Pot to Sauté on Low. Cook uncovered for 15 to 30 minutes, stirring frequently, until the apple butter becomes thick, dark and glossy. Stir more frequently as it thickens to prevent scorching.
Drag a spatula across the bottom of the pot. The apple butter is ready when the trail remains visible briefly before slowly filling back in.
Turn off the Instant Pot and stir in the vanilla extract. For an extra-smooth consistency, allow the apple butter to cool slightly before carefully blending it with an immersion blender.
1 tsp vanilla extract
Allow the apple butter to cool before transferring it to airtight containers. It will continue to thicken as it cools.
