Preheat the oven to 350°F (175°C).
Peel, core, and thinly slice the apples.
In a large mixing bowl, combine sliced apples, granulated sugar, cinnamon, nutmeg, and dried cranberries.
In another bowl, mix oats, flour, brown sugar, and a pinch of salt. Add cold, cubed butter and blend until you have coarse crumbs.
Layer the spiced apple mixture in a baking dish.
Sprinkle the crumble topping over the apples, covering them completely.
Bake for 40-45 minutes until the topping is golden brown and apples are bubbling.
Serve warm with vanilla ice cream for a delightful treat!
