Ingredients
- 5 cups (about 5 medium) peeled and thinly sliced apples (such as Granny Smith or Honeycrisp)
- 2 tablespoons granulated sugar
- 1 teaspoon ground cinnamon
- 1 tablespoon lemon juice (to prevent browning)
- 1 cup old-fashioned rolled oats
- 1/2 cup all-purpose flour
- 1/2 cup packed brown sugar
- 1/4 teaspoon salt
- 1/2 teaspoon ground cinnamon
- 6 tablespoons unsalted butter, cold and cut into small pieces
Instructions
- Prepare the apples Preheat your oven to 350°F (175°C). Toss the sliced apples with granulated sugar, ground cinnamon, and lemon juice. Spread evenly in a greased 8×8-inch baking dish.
- Make the crumble topping In a bowl, combine oats, flour, brown sugar, salt, and ground cinnamon. Add the cold butter pieces and use your fingers or a pastry cutter to mix until the mixture resembles coarse crumbs.
- Assemble and bake Sprinkle the crumble mixture evenly over the apples in the baking dish. Bake uncovered for 35 minutes or until the topping is golden brown and the apples are bubbly and tender.
- Cool and serve Let the crumble cool for at least 10 minutes before serving to allow the juices to thicken slightly. Serve warm, optionally with vanilla ice cream or whipped cream.
Helpful Tips

- Make sure to cool the dessert before serving to avoid burns and to let the filling thicken slightly.
