Easy Caramel Apple Crumble Bars – Best Fall Dessert

I remember the first time I tried a caramel apple at a street fair in Brooklyn – the crunch, the sticky sweetness, the tart apple underneath. That memory inspired these bars, which capture all that flavor in a simple, shareable form.

These Caramel Apple Crumble Bars are a fantastic way to use up a bag of apples before they go soft. They're perfect for potlucks, bake sales, or just a cozy weekend treat. The buttery crust and crumble are made from the same dough, so you get maximum flavor with minimal fuss.

About the Ingredients

1 1/2 cups (190g) all-purpose flour

Provides structure. You can substitute a 1:1 gluten-free baking flour for a GF version.

1 1/2 cups (120g) old-fashioned rolled oats

Adds a chewy texture. Quick oats work in a pinch, but the bars will be less textured.

1 cup (200g) packed light brown sugar

Adds moisture and a deep, molasses-like sweetness. Dark brown sugar will intensify the flavor.

1 teaspoon ground cinnamon

Warm spice that complements apples. You can use apple pie spice for a more complex flavor.

1/2 teaspoon baking soda

Helps the crust crisp up. No substitutions.

1/4 teaspoon salt

Balances sweetness. Use fine sea salt.

3/4 cup (170g) unsalted butter, melted

For richness and binding. You can use salted butter, but omit the added salt.

4 cups (about 500g) peeled, cored, and thinly sliced apples (about 4 medium)

Tart varieties like Granny Smith or Honeycrisp hold up best. Mix sweet and tart for complexity.

1/2 cup (60g) all-purpose flour

For the filling thickener. You can use cornstarch instead.

1/2 cup (100g) granulated sugar

Sweetens the filling. You can reduce to 1/3 cup if your apples are very sweet.

1 teaspoon lemon juice

Prevents browning and brightens flavor. Fresh is best, but bottled works.

1/2 cup (120ml) caramel sauce, plus more for drizzling

Use store-bought or homemade. For a richer flavor, warm it slightly before drizzling.

Tips & Tricks

• Don't overmix the crust dough; it should be crumbly but hold together when pressed.
• Slice apples uniformly (about 1/4-inch thick) so they cook evenly.
• Let the bars cool completely before cutting to get clean slices.

Step-by-Step Instructions

1. Preheat and Prep

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

2. Make the Crust Mixture

In a large bowl, whisk together 1 1/2 cups flour, oats, brown sugar, cinnamon, baking soda, and salt. Pour in the melted butter and stir until the mixture forms a crumbly dough.

3. Press the Crust

Press about two-thirds of the crumb mixture evenly into the bottom of the prepared pan. Make sure it's compact and even. Bake for 10 minutes, until lightly golden. Remove from oven and set aside.

4. Toss the Apples

In a separate bowl, combine the sliced apples, 1/2 cup flour, granulated sugar, and lemon juice. Toss until the apples are evenly coated.

5. Layer the Filling

Spread the apple mixture over the baked crust. Drizzle the caramel sauce evenly over the apples.

6. Add the Crumble Topping

Sprinkle the remaining crumb mixture over the apples, covering them completely. Gently press the topping down.

7. Bake Until Golden

Bake for 30-35 minutes, until the topping is golden brown and the filling is bubbling at the edges. The apples should be tender when pierced with a fork.

8. Cool and Serve

Let the bars cool completely in the pan on a wire rack. Once cool, lift out using the parchment, cut into 6 bars, and drizzle with extra caramel if desired.

Delicious Variations

Make a gluten-free version by using a 1

1 gluten-free flour blend and certified gluten-free oats.

• Add 1/2 cup chopped pecans or walnuts to the crumble topping for extra crunch.
• Swap the apples with pears and add a teaspoon of grated fresh ginger for a spiced twist.
