Apple Butter in the Crockpot

This recipe is from a Year of Slow Cooking. The recipe is super tasty and made the house smell so wonderful. The kids loved the flavor. This is a kepper.
Thank you for pushing me to make this. This beats the lid off of store-bought apple butter.

The Ingredients.
16-18 large apples fit in my 7 quart crockpot
--2 tsp cinnamon
--2 cups white sugar
--1 cup brown sugar
--1/2 tsp apple pie spice
--1 T vanilla

The Directions.

Peel and quarter the apples.Place all of the quartered apples into your crockpot. Add 1 tablespoon of vanilla. Cover and cook on low for 8 hours.

When the cooking is done, mash the apples with a potato masher. Stir in the sugars, cinnamon, and cloves.
Cover again and cook on low for 6 hours. Allow to cool and serve.
