Weigh out the ingredients
You'll need brown sugar, apples, vanilla, molasses, apple cider, spices, and salt.
Combine the ingredients
In a large heavy bottomed pot, add all ingredients except vanilla. You can either peel the apples or leave the peels on.
Place over low-medium heat and cook for one hour, stirring occasionally until the juices are simmering and the apples are very soft.
Cook over stovetop
Use an immersion blender (or transfer to a blender) to blend the apple mixture until it becomes a smooth puree. Continue cooking for an additional hour, stirring occasionally until thick and a deep shade of brown.
Remove the pot from heat and stir in the tablespoon of vanilla. To get an extra smooth apple butter, pour it through a fine mesh sieve into a large bowl until it reaches your desired consistency.
Transfer the apple butter to glass jars and chill in the fridge. Enjoy with toast, biscuits, muffins, or by the spoonful!
