Place your peeled and sliced apples into a 2.5 quart or larger slow cooker. In a small bowl, mix together maple syrup, cinnamon, cloves and salt and pour over the apples. Cook on low for 8 hours.

Stir in your vanilla extract, breaking up any large chunks of apples that remain and cook for another 2 hours, uncovered.

Pour your apples into your food processor or use an immersion blender and puree. Allow it to cool and spoon it into jars. Enjoy!
