A warm and comforting apple crisp with spiced fresh apples and a golden oat topping. This classic dessert is easy to make, perfect for using up apples, and tastes even better served with vanilla ice cream and caramel drizzle.
Preheat the oven to 350℉. Lightly grease a 9×9-inch baking dish.
In a large bowl, toss the sliced apples with granulated sugar, brown sugar, cinnamon, nutmeg, allspice, lemon juice, and cornstarch until evenly coated. Spread into the baking dish.
In a medium bowl, combine oats, flour, both sugars, cinnamon, and salt. Cut in the cold butter with a pastry cutter or your fingers until coarse crumbs form. Stir in nuts.
Sprinkle the topping evenly over the apple mixture, pressing lightly to help it stick.
Bake 40-50 minutes, until the topping is golden brown and the juices are bubbling around the edges. If topping browns too fast, tent loosely with foil for the last 10 minutes.
Let cool 10 minutes before serving. Scoop into bowls with vanilla ice cream and drizzle with caramel sauce.
Notes
Apple choice: Using half Granny Smith and half Honeycrisp gives the best balance of tart and sweet. If using all tart apples, add 1-2 tablespoons more brown sugar to the filling.
Texture check: The true sign of doneness is bubbling juices around the edges and a deep golden topping.
Make-ahead tip: Prepare the filling and dry topping a day in advance. Add the butter to the topping just before baking.
Storage: Cover leftovers and refrigerate up to 3 days. Reheat at 325℉ until the topping crisps again.
