Preheat the Oven:

Preheat your oven to 350°F (175°C). Grease a 9x9-inch baking dish and set aside.

Prepare the Fruit Filling:

In a mixing bowl, toss the sliced apples and chopped figs with brown sugar, cinnamon, lemon juice, and cornstarch until evenly coated. Transfer the fruit mixture into the prepared baking dish.

Make the Crumble Topping:

In another bowl, combine the flour, oats, sugar, and cinnamon. Add the cold, cubed butter and use a fork or pastry cutter to work the butter into the dry ingredients until the mixture resembles coarse crumbs.

Assemble the Crumble:

Evenly distribute the crumble topping over the fruit mixture in the baking dish.

Bake:

Bake in the preheated oven for 35–40 minutes, or until the topping is golden and the fruit is bubbling around the edges.

Cool and Serve:

Let the crumble cool for a few minutes before serving. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence.
