Creating Slow Cooker Apple Butter is straightforward if you follow these simple steps:

1. Prepare the Apples: Peel, core, and chop the apples into small pieces.
2. Add Ingredients to the Slow Cooker: Place the chopped apples in the slow cooker. Add granulated sugar, brown sugar, cinnamon, nutmeg, allspice, salt, lemon juice, and optional vanilla extract.
3. Mix Well: Stir the ingredients until the apples are evenly coated with the sugars and spices.
4. Cook: Cover the slow cooker and set it on low for 6 to 8 hours. Stir occasionally, if possible.
5. Blend Smooth: Once the apples are tender and the mixture looks caramelized, use an immersion blender to blend until smooth. Alternatively, transfer to a blender and blend in batches, taking care not to burn yourself.
6. Cook Again: Return the blended mixture to the slow cooker and cook uncovered on low for an additional 1 to 2 hours to thicken, stirring occasionally.
7. Test and Store: Once the apple butter reaches your desired consistency, taste and adjust sweetness if needed. Allow to cool, then store in sterilized jars.
