01 - Preheat your oven to 350°F (175°C).
02 - In a large bowl, combine apples, pears, cranberries, dried apricots, granulated sugar, lemon juice, cinnamon, nutmeg, and 2 tbsp flour. Toss until fruit is evenly coated.
03 - Transfer the fruit mixture into a greased 9-inch (23 cm) baking dish, spreading it evenly.
04 - In another bowl, mix the oats, ¾ cup flour, brown sugar, salt, and nuts (if using). Add the cold, cubed butter and use your fingers or a pastry cutter to blend until the mixture resembles coarse crumbs.
05 - Sprinkle the topping evenly over the fruit.
06 - Bake for 40 minutes, or until the topping is golden brown and the fruit is bubbling.
07 - Let cool slightly before serving. Serve warm, optionally with vanilla ice cream or whipped cream.
