Using a grapefruit spoon or paring knife, cut out the apple cores, leaving at least one inch at the bottom intact. You can use an apple corer, but you will need to make the whole larger with a paring knife.
Mix together ½ cup of rolled oats, ½ cup of chopped walnuts, ¼ cup of pumpkin seeds, 1 teaspoon of cinnamon, 2 tablespoons of maple syrup, 1 tablespoon of golden raisins, and 1 teaspoon of vanilla.
Stuff this mixture inside each apple hole and top with about ½ teaspoon of butter.
Put the apples in an oven-safe dish and pour ¾ boiling water into the bottom of the dish.
Bake for 30 to 45 minutes until the apples are tender, but not mushy.
Take out of the oven and add extra maple syrup or whipped cream as toppings.
