Apple-Oatmeal Crumble Bars

1. To make the filling, combine the apples, apple cider, lemon juice, cornstarch, cinnamon, and salt in a medium skillet over medium heat. Cook for 4 to 5 minutes, stirring occasionally, until the apples begin to soften and the liquid thickens slightly. Remove from the heat and set aside.

2. To make the crust and crumb topping, preheat the oven to 425°F. Lightly grease an 8-inch square baking dish.

3. Combine the flour, sugars, oats, and salt in the bowl of a food processor and pulse a few times to combine. Add the butter and pulse until the butter is the size of peas and the mixture is crumbly. Press half of the mixture over the bottom of the prepared pan. Spread the apples mixture evenly over the crust and sprinkle the remaining crumb mixture over the top.

4. Bake for 25 to 30 minutes, until the top is golden brown. Remove from the oven and let cool completely before cutting.
