Peel and cut the apples. In a pan, combine them with 70 g brown sugar and the cinnamon. Cook, stirring occasionally, for 5–7 minutes, until softened and the sugar has caramelized slightly.
Transfer the cooked fruit mixture to a baking dish.
In another bowl, combine the flour, oats, 35 g brown sugar, and white sugar. Add the cold cubed butter and rub it into the dry mixture with your fingertips until it resembles coarse breadcrumbs.
Sprinkle the crumble topping evenly over the fruit.
Bake for 25–30 minutes, until the top is golden and the edges are bubbling.
Let cool for 7–10 minutes before serving. Serve with a scoop of ice cream if desired.
