Ingredients
- 5 cups Granny Smith apples, peeled, cored and thinly sliced (about 6–7 apples)
- Juice from ½ lemon
- ½ cup light brown sugar
- ½ tablespoon flour
- ½ teaspoon ground cinnamon
- 1 cup quick-cooking oats
- 1 cup flour
- 1 cup packed brown sugar
- ¼ teaspoon baking powder
- ¼ teaspoon baking soda
- 1 teaspoon ground cinnamon
- ½ cup cold butter, cubed
Instructions
Preheat oven to 375°F. Prepare a 9- by 13-inch pan with baking spray or coat with butter.
Mix the crumb mixture ingredients: oats, flour, brown sugar, baking powder, baking soda and cinnamon. Add in the cubed butter and use your hands to combine until pea-sized and fully coated. Spread half of the mixture into the prepared pan and press down firmly to create the bottom crust.
Place the sliced apples in a bowl and toss with lemon juice. Add the apple filling ingredients: brown sugar, flour and cinnamon. Toss gently to ensure that every apple slice is coated evenly.
Pour the apple mixture on top of the bottom crust, then loosely cover the top of the apples with the remaining crumb topping.
Bake uncovered for 25–35 minutes. Serve warm with ice cream, caramel and walnuts.
