Ingredients

1 ½ cups all-purpose flour

½ cup rolled oats

½ cup packed light brown sugar

½ teaspoon ground cinnamon

¼ teaspoon ground nutmeg

½ teaspoon salt

½ cup (1 stick) unsalted butter, cold and cut into cubes

6 medium apples (Granny Smith, Honeycrisp, or a mix), peeled, cored, and thinly sliced

¾ cup granulated sugar

¼ cup packed light brown sugar

¼ cup apple cider or apple juice

2 tablespoons unsalted butter

1 teaspoon ground cinnamon

½ teaspoon ground nutmeg

¼ teaspoon salt

1 tablespoon cornstarch

1 tablespoon cold water

1 teaspoon vanilla extract

½ cup all-purpose flour

½ cup rolled oats

½ cup packed light brown sugar

¼ cup chopped pecans or walnuts (optional)

½ teaspoon ground cinnamon

¼ cup (½ stick) unsalted butter, cold and cut into cubes

Instructions

Step 1: Preheat the oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan or line it with parchment paper for easier cleanup.

Step 2: In a large bowl, whisk together 1 ½ cups flour, ½ cup oats, ½ cup brown sugar, ½ teaspoon cinnamon, ¼ teaspoon nutmeg, and ½ teaspoon salt.

Step 3: Cut in ½ cup cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Avoid overmixing.

Step 4: Press about two-thirds of this crust mixture evenly into the bottom of the prepared pan.

Step 5: In a large skillet over medium heat, combine the sliced apples, ¾ cup granulated sugar, ¼ cup brown sugar, apple cider, 2 tablespoons butter, 1 teaspoon cinnamon, ½ teaspoon nutmeg, and ¼ teaspoon salt.

Step 6: Cook, stirring occasionally, until the apples soften and caramelize slightly, about 10 to 15 minutes.

Step 7: In a small bowl, whisk the cornstarch and cold water to create a slurry.

Step 8: Stir the cornstarch slurry into the apple mixture and cook for 1 to 2 minutes more until thickened. Remove from heat and stir in vanilla extract.

Step 9: Pour the apple filling evenly over the crust in the baking pan.

Step 10: In a medium bowl, mix ½ cup flour, ½ cup oats, ½ cup brown sugar, chopped nuts if using, and ½ teaspoon cinnamon.

Step 11: Cut in ¼ cup cold butter until the topping is crumbly but not overworked.

Step 12: Sprinkle the crumble topping evenly over the apple filling.

Step 13: Bake for 35 to 40 minutes or until the topping is golden brown and the filling bubbles around the edges.

Step 14: Allow the bars to cool completely in the pan before cutting into squares to serve.

Tips & Variations

Use a mix of tart and sweet apples for a balanced flavor and texture.

For a nut-free version, simply omit the pecans or walnuts in the topping.

Chilling the topping mixture before sprinkling can help maintain a crumbly texture during baking.

Drizzle with caramel sauce before serving for an extra indulgent treat.

FAQs

Can I use frozen apples for this recipe?

Fresh apples are best for this recipe to maintain texture and moisture. If using frozen apples, thaw and drain excess liquid thoroughly to avoid a soggy filling.

How do I prevent the crust from becoming soggy?

Pressing the crust firmly into the pan and cooking the apple filling until slightly caramelized helps reduce excess moisture. Lining the pan with parchment paper also aids in even baking and easier removal.
