Absolutely! To make apple butter in a crockpot, add all ingredients except for the vanilla to your crockpot and cook on low for about 10 hours, stirring occasionally. Uncover, stir in the vanilla, and cook for another 2 hours, then blend until smooth. Follow this recipe to make apple butter in an instant pot, add all of the ingredients to your instant pot, set the vent to sealing, then pressure cook (manual) for 15 minutes at high pressure. Let release naturally for 20 minutes, then turn the dial to vent and let the remaining steam release. Blend the apple mixture until smooth. If the mixture still seems runny, cook it on the sauté function until thickened.
