Easy Spiced Apple Crumble Bars – Best Fall Treat

If you've got a bag of apples sitting on the counter that need using up, these Spiced Apple Crumble Bars are the answer. They're a straightforward, no-fuss dessert that delivers big on flavor without requiring any special equipment or advanced baking skills.

The recipe is built on a classic shortbread-style crust, a layer of spiced apples, and a buttery oat crumble. Each component comes together quickly, and the bars bake in about 35 minutes. You'll get a satisfying contrast of textures: crisp topping, tender apples, and a firm, buttery base.

These bars are perfect for a weeknight treat, a bake sale, or a casual gathering. They hold their shape well, making them easy to pack and serve. Plus, they're a great way to use up any variety of apples you have on hand—from tart Granny Smith to sweet Honeycrisp.

About the Ingredients

1 ½ cups (190g) all-purpose flour

Provides structure for the crust and crumble. Substitute with a 1:1 gluten-free flour blend if needed.

½ cup (100g) granulated sugar

Sweetens the crust. You can reduce to ⅓ cup for a less sweet base.

½ cup (115g) cold unsalted butter, cubed

Cold butter creates a flaky texture. Use salted butter and reduce added salt by ¼ teaspoon if that's what you have.

1 teaspoon vanilla extract

Adds depth. Use imitation vanilla to save money without sacrificing much flavor.

4 cups (about 4-5 medium) apples, peeled and thinly sliced

Any crisp apple works; Granny Smith holds its shape well, while Honeycrisp adds sweetness. Mix varieties for complexity.

2 tablespoons lemon juice

Prevents browning and brightens the apple flavor. Use bottled lemon juice in a pinch.

¼ cup (50g) packed brown sugar

Adds molasses notes and helps caramelize the apples. Dark brown sugar gives a deeper flavor.

1 teaspoon ground cinnamon

The key spice. For a warmer flavor, add a pinch of nutmeg or allspice.

1 cup (85g) old-fashioned rolled oats

Provides the crumble texture. Quick oats work but yield a softer topping.

¼ teaspoon salt

Balances sweetness and enhances flavors. Omit if using salted butter.

Tips & Tricks

• Use cold butter for the crust and crumble; it creates a flakier texture.
• Slice apples uniformly (about ¼-inch thick) so they cook evenly.
• Don't overmix the crumble; you want pea-sized butter pieces for a crisp topping.

Step-by-Step Instructions

1. Preheat Oven

Preheat your oven to 375°F (190°C). Line a 9×9-inch baking pan with parchment paper, leaving overhang for easy removal.

2. Make Crust

In a medium bowl, whisk together 1 cup (125g) of the flour and granulated sugar. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Stir in the vanilla. Press the mixture firmly into the prepared pan. Bake for 12-15 minutes, until the edges are lightly golden. Set aside to cool slightly.

3. Prepare Apples

In a large bowl, toss the sliced apples with lemon juice, brown sugar, and cinnamon. Set aside while you make the topping.

4. Make Crumble

In the same bowl used for the crust (wipe it out), combine the remaining ½ cup (65g) flour, oats, and salt. Cut in the remaining ¼ cup (60g) cold butter until the mixture forms clumps.

5. Assemble Bars

Spread the apple mixture evenly over the pre-baked crust. Sprinkle the crumble topping over the apples, covering them completely.

6. Bake

Bake for 20-25 minutes, until the topping is golden brown and the apples are bubbling at the edges. A toothpick inserted into the center should come out with moist crumbs, not wet batter.

7. Cool and Slice

Allow the bars to cool completely in the pan on a wire rack, about 1 hour. Once cool, lift out using the parchment and slice into 6 bars.

Delicious Variations

• Add ½ cup of chopped walnuts or pecans to the crumble for extra crunch.
• Substitute ½ cup of dried cranberries or raisins for some of the apples.
• Drizzle with a simple powdered sugar glaze (1 cup powdered sugar + 2-3 tablespoons milk) after cooling.
