01 - Preheat oven to 350°F (180°C).
02 - Core each apple, keeping the base intact to form a well. Arrange apples upright in a baking dish.

04 - Spoon the filling into the center of each apple, pressing gently to pack the mixture.
05 - Pour the apple cider or water around the apples in the bottom of the baking dish.
06 - Bake for 30 to 35 minutes, until apples are tender yet still hold their shape.
07 - Remove baked apples from oven and serve warm. Drizzle with extra maple syrup if desired.
