6lbsapples(approximately; see *; peeled, cored and cut into small ½ inch pieces)
Place peeled and chopped apples in the base of a 6 quart slow cooker. Stir in the spices.
Cover and cook on high for 4-5 hours or on low for 8-10 hours. You may want to stir it partway through (only once).
After cooking through, blend it until smooth using an immersion blender. Alternatively you can work in batches and carefully puree the apple butter in a stand blender.
Cool and store in the fridge for up to 2 weeks. You may freeze for up to 6 months; make sure to leave lids ajar and to leave space for expansion if you are freezing right in the jars.
*I honestly did not measure, but filled the slow cooker all the way to the top with peeled & chopped apples. They will reduce in size substantially during the cook time so make sure to fill it right to the top!
