Oman today_ To prepare apple crumble, start by gathering the ingredients for two layers: the apple layer and the crumble topping. For the apple layer, you will need 5 medium apples (preferably Gala or Granny Smith), peeled and sliced, 2 tablespoons of brown sugar, 1 teaspoon of cinnamon, 1 tablespoon of flour, and 1 tablespoon of lemon juice. For the crumble topping, you’ll need 1 cup of all-purpose flour, 1/2 cup of brown sugar, 1/2 cup of rolled oats, 1/2 cup of cold, diced butter, and 1/4 teaspoon of salt.
Preheat your oven to 180°C (350°F) and grease a 20×20 cm (8×8 inch) baking dish with butter. For the apple layer, combine the sliced apples, brown sugar, cinnamon, flour, and lemon juice in a large bowl, mixing until the apples are well-coated. Spread this mixture evenly in the prepared baking dish.
To make the crumble topping, mix the flour, brown sugar, oats, and salt in another bowl. Add the cold, diced butter and use your fingertips or a fork to combine until the mixture resembles coarse crumbs. Sprinkle the crumble topping evenly over the apple layer.
Bake the dish in the preheated oven for 40 to 45 minutes, until the topping turns golden and crisp and the apples are tender. Once out of the oven, allow it to cool slightly before serving. Pair it with vanilla ice cream or whipped cream for a classic and delightful dessert. Perfect for gatherings or a cozy afternoon treat.
