Preheat your oven to 350°F (175°C).

Wash your apples thoroughly, then slice them in half vertically and core them.

In a mixing bowl, combine melted unsalted butter, brown sugar, and ground cinnamon. Stir until smooth.

Place the apple halves cut side up in a greased baking dish and fill them with nuts or dried fruits if using.

Spoon the topping over each apple half and ensure they are well coated.

Pour a splash of apple juice or water into the bottom of the baking dish.

Cover the dish with foil and bake for 25 minutes.

Remove the foil and bake for an additional 15-20 minutes until tops are golden brown.

Let cool slightly before serving with whipped cream or ice cream.
