Place the peeled, cored, and chopped apples in a large slow cooker.

In a bowl, combine the granulated sugar, brown sugar, ground cinnamon, ground nutmeg, ground cloves, ground allspice, and salt. Sprinkle over the apples and stir to coat evenly.
03 -
Cover the slow cooker and cook on low for 10-12 hours, stirring occasionally, until the apples are very soft and dark brown. If needed, cook for an additional 1-2 hours to reach the desired consistency.

Use an immersion blender to puree the apple mixture until smooth. Alternatively, blend the mixture in batches using a blender.
05 -
Stir in the vanilla extract and caramel sauce until well combined.

If the apple butter is still too thin, continue cooking uncovered on low for another 1-2 hours, stirring occasionally, until it reaches desired thickness.
07 -
Let the apple butter cool to room temperature. Transfer to sterilized jars or airtight containers and store in the refrigerator for up to 2 weeks. Alternatively, process in a water bath for longer storage.

Serve the salted caramel apple butter on toast, biscuits, or pancakes, or use as a dessert topping. Optionally, sprinkle a small amount of sea salt on top before serving.
