If using cranberries here, add two tablespoons more brown sugar to apple-berry mixture, since cranberries are especially tart.
5 Golden Delicious apples, peeled, cored, and sliced
2 cups fresh or frozen blackberries, blueberries, cranberries or raspberries
3/4 cup packed brown sugar
1 1/2 teaspoons ground cinnamon
1/3 cup unsifted all-purpose flour
1/8 teaspoon salt
5 tablespoons butter
1/3 cup quick rolled oats
1. Heat oven to 375 degrees F. Lightly grease a 1 1/2- to 2-quart baking dish. In large bowl, combine apples, berries, 1/4 cup brown sugar, and 1/2 teaspoon cinnamon; toss to blend. Place apple-berry mixture in prepared dish.
2. In medium-sized bowl, combine flour, salt, remaining 1/2 cup brown sugar, and 1 teaspoon cinnamon. With pastry blender or two knives, cut in butter until mixture is crumbly; stir in oats. Sprinkle mixture over apples and bake 40 to 45 minutes or until apples are tender and topping is crisp and golden.
