Pre-heat oven to 375°. Wash and core apples. Use a spoon to scoop out a small bowl shape, being sure not to go all the way through to the bottom of the apple. You are making a little bowl within the apple in which to place your other ingredients.
Into each apple, pack 1 tablespoon each of the brown sugar, butter, raisin, and cider.
Place apples onto a baking sheet or into a cast iron skillet. Sprinkle chopped walnuts into each apple (skip this ingredient if including pecan sugar cinnamon butter recipe). Sprinkle lightly with cinnamon.
Bake 20-30 minutes or until apples are soft.
