Core the apples and chop them into quarters. (Chopping is optional but helps them cook down faster.)
6 pounds apples
Add the apples, cider, sugar, cinnamon, spices, vanilla and salt to the Instant Pot. Seal the lid and pressure cook on high for 25 minutes. Allow the Instant Pot to naturally release pressure for 20 minutes.
½ cup apple cider, 1 cup dark brown sugar, ½ teaspoon ground allspice, ½ teaspoon ground cloves, 2 cinnamon sticks, 1 tablespoon vanilla extract, ½ teaspoon kosher salt
Remove the cinnamon sticks, then blend the apple mixture smooth with an immersion blender.
Press the sauté button and cook the apple butter, stirring occasionally, until it reaches your desired consistency. For a thick, dark apple butter, sauté for about 45 minutes, stirring occasionally. If you prefer a lighter, looser texture (more like applesauce), cook for 20-30 minutes.
Transfer the apple butter to a jar and let it cool to room temperature before refrigerating.
