Step 1

Prepare crockpot by spraying well with cooking spray or use a crockpot liner.

Step 2

Peel, core, and slice all of the apples and place them in the crockpot.

Step 3

In a separate bowl, combine the sugars, cinnamon, nutmeg, and salt. Pour the mixture over the apples and stir well, making sure to coat all of the apples.

Step 4

Set the crockpot on low for 10 hours. After the 10 hours, mash any chunks of apple that remain. Allow to cook for an additional 2 hours.

Step 5

Remove the lid and use an immersion blender to blend the apple butter until it's smooth. If you prefer, you can let the apple butter cook a little longer with the lid slightly ajar to let it thicken up some more.

Step 6

Once the apple butter is finished, transfer to containers and allow to cool completely, then refrigerate.
