Salted Caramel Apple Pie Bars with Oat Streusel

These Salted Caramel Apple Pie Bars have all the cozy flavors of classic apple pie in an easy-to-serve dessert. They start with a buttery shortbread crust, followed by a layer of fresh apples tossed with cinnamon, nutmeg, and sugar. On top, a golden oat streusel adds a delicious crumbly texture, while a drizzle of salted caramel brings everything together. Instead of preparing a traditional pie crust and shaping an entire pie, you can make these apple pie bars in an 8-inch square baking pan and cut them into individual squares. They’re a wonderful dessert for fall gatherings, holiday celebrations, or whenever you’re craving something with apples and caramel.

Salted Caramel Apple Pie Bars Ingredients

This recipe has three main layers: the shortbread crust, spiced apple filling, and oat streusel topping. A salted caramel drizzle and optional flaky sea salt finish the bars.

Streusel Topping

• Old-fashioned rolled oats: Add texture and a slightly chewy, crumbly finish to the topping.
• Brown sugar: Gives the streusel its sweetness and complements the cinnamon.
• Ground cinnamon: Adds warmth and pairs beautifully with the apples.
• All-purpose flour: Helps hold the streusel ingredients together.
• Cold unsalted butter: Cutting cold butter into the dry ingredients creates the coarse crumb texture needed for streusel.

Shortbread Crust

• Unsalted butter: Melted butter provides the rich, buttery foundation of the crust.
• Granulated sugar: Adds sweetness and balances the buttery flavor.
• Pure vanilla extract: Gives the crust a warm flavor.
• Salt: Enhances the other ingredients.
• All-purpose flour: Creates the structure of the shortbread base.

Apple Filling

• Fresh apples: Two large apples provide the main filling. Peeling and slicing them into thin pieces helps create even layers.
• All-purpose flour: Helps bind the apple filling ingredients.
• Granulated sugar: Sweetens the apples.
• Ground cinnamon: Adds the classic spiced apple flavor.
• Ground nutmeg: Complements the cinnamon and gives the filling additional warmth.

Garnish

• Salted caramel sauce: Drizzled over the cooled and sliced bars for a sweet, rich finish. Homemade or store-bought caramel sauce works.
• Flaky sea salt: Optional, but adds a pleasant salty contrast to the caramel.

Helpful Tips for Making Apple Pie Bars

• Use two apple varieties: Combining a tart apple, such as Granny Smith, with a sweeter variety, such as Pink Lady or Honeycrisp, creates a nice balance of flavor and texture.
• Keep the streusel butter cold: Cold, cubed butter helps create the coarse crumbs that give the topping its texture.
• Measure the flour correctly: Spoon the flour into your measuring cup and level it rather than packing it down.
• Press the crust evenly: Spread the shortbread mixture across the bottom of the pan so the base bakes evenly.
• Arrange the apples tightly: The filling may look like too many apple slices at first, but layer them tightly and press them down to fit.
• Chill before slicing: Allow the bars to cool at room temperature before refrigerating for at least 2 hours. This makes them easier to lift out and cut into squares.
• Add caramel before serving: Drizzle the salted caramel over the bars after cutting for an attractive finish.

How to Make Salted Caramel Apple Pie Bars

Step 1: Prepare the Baking Pan

Preheat the oven to 300°F (149°C). Line the bottom and sides of an 8-inch square baking pan with parchment paper, leaving some overhang on all sides.

The parchment overhang will help you lift the finished bars out of the pan.

Step 2: Make the Oat Streusel

In a medium bowl, whisk together the old-fashioned rolled oats, brown sugar, ground cinnamon, and all-purpose flour.

Add the cold, cubed butter. Use a pastry blender, two forks, or your hands to cut the butter into the dry ingredients until the mixture resembles coarse crumbs.

Place the streusel in the refrigerator while you prepare the crust.

Step 3: Prepare the Shortbread Crust

In a medium bowl, stir together the melted butter, granulated sugar, vanilla extract, and salt.

Add the all-purpose flour and mix until everything is combined.

Transfer the mixture to the prepared baking pan and press it evenly across the bottom.

Bake for 20 minutes, or until the edges are lightly browned.

While the crust bakes, prepare the apple filling.

Step 4: Prepare the Apple Filling

Peel and thinly slice the two large apples into approximately 1/4-inch-thick slices.

In a large bowl, combine the sliced apples with the all-purpose flour, granulated sugar, ground cinnamon, and ground nutmeg.

Stir until all the apple slices are evenly coated, then set aside.

Step 5: Assemble the Layers

Once the shortbread crust has finished baking, remove it from the oven and increase the oven temperature to 350°F (177°C).

Pour the prepared apple filling over the warm crust.

Spread and press the apple slices into an even layer. The apples may initially look like too much filling, but arrange them tightly and press them down to fit.

Remove the chilled streusel from the refrigerator and sprinkle it evenly over the apples.

Step 6: Bake the Apple Pie Bars

Return the pan to the oven and bake at 350°F (177°C) for 30–35 minutes.

The bars are ready when the streusel topping is golden brown.

Remove the pan from the oven and allow the bars to cool at room temperature for at least 20 minutes.

Step 7: Chill the Bars

After the initial cooling period, transfer the pan to the refrigerator.

Chill for at least 2 hours. This step helps the layers set and makes the bars easier to cut.

Step 8: Slice and Add the Salted Caramel

Once chilled, grip the parchment paper overhang and carefully lift the bars out of the baking pan.

Transfer them to a cutting board and cut into 12–16 squares.

Drizzle homemade or store-bought salted caramel sauce over the bars. Finish with flaky sea salt if desired.

These apple pie bars can be enjoyed warm, cold, or at room temperature.

Best Apples for Salted Caramel Apple Pie Bars

The apples you choose can influence the overall flavor and texture of the filling.

The original recipe recommends using two different varieties for more depth of flavor.

• Granny Smith: A tart apple that balances the sweetness of the brown sugar and caramel.
• Pink Lady: Offers a sweet and slightly tart flavor.
• Honeycrisp: Adds sweetness and a pleasant apple flavor.

Combining one tart variety with one sweet variety is a great way to create a balanced apple filling.

Serving Suggestions

These salted caramel apple pie bars are delicious as a fall dessert or as part of a holiday dessert table.

Serve them in individual squares with the caramel drizzle and optional flaky sea salt. You can enjoy them warm, cold, or at room temperature, depending on your preference.

They’re also convenient for sharing because the shortbread crust and layered filling make them easy to portion without serving an entire pie.
