Apple Butter

Place the apples in a slow cooker.
Add the sugars, cinnamon, salt and vanilla to the crockpot. Mix well.
Cook in slow cooker on low for about 10 hours, stirring every couple hours. The apple butter should be thick and dark brown.
If desired, use a blender to puree the apple butter until smooth.
Cover and refrigerate for up to two weeks or freeze in small containers.

Enjoy!
