How to Make Salted Caramel Apple Pie Bars

Step 1: Prepare the Pan

Preheat the oven to 350°F. Line a 9 × 13-inch baking pan with parchment paper, leaving some overhang on the long sides. This makes the bars easier to lift out after cooling.

Step 2: Make the Shortbread Crust

In a medium bowl, whisk together the flour, granulated sugar, and salt. Pour in the melted butter and stir until the mixture forms soft, evenly moistened crumbs.

Step 3: Press and Bake the Crust

Transfer the crust mixture to the prepared pan. Press it firmly and evenly across the bottom, paying special attention to the corners.

Bake for 15–18 minutes, until the edges are just beginning to turn lightly golden. Remove the pan from the oven and let the crust cool while you prepare the filling. Keep the oven at 350°F.

Step 4: Prepare the Apples

Peel, core, and thinly slice the apples. Try to make the slices similar in thickness so they cook evenly.

Place them in a large bowl and toss with the granulated sugar, brown sugar, flour, cinnamon, nutmeg, lemon juice, and salt. Mix until the apples are evenly coated.

Step 5: Make the Crumble Topping

In another bowl, combine the oats, flour, brown sugar, and cinnamon. Pour in the melted butter and stir with a fork until the mixture forms clumps.

Step 6: Assemble the Bars

Arrange the apple slices evenly over the baked crust. Spread them into a level layer so each bar gets a good amount of filling.

Scatter the oat crumble over the apples, covering them as evenly as possible. Leave some larger crumbs for a pleasantly crisp topping.

Step 7: Bake

Return the pan to the oven and bake for 30–37 minutes, until the topping is golden and the apples are tender when pierced with a knife.

If the topping browns too quickly, loosely cover the pan with foil for the last few minutes.

Step 8: Cool Completely

Place the pan on a cooling rack and let the bars cool completely, at least 2 hours. The filling needs time to set. Cutting the bars while warm may cause them to fall apart.

For especially neat squares, chill the cooled pan in the refrigerator for 30–45 minutes before slicing.

Step 9: Add Caramel and Sea Salt

Lift the bars from the pan using the parchment overhang. Drizzle with caramel sauce and sprinkle lightly with flaky sea salt.

Cut into 16 squares with a sharp knife, wiping the blade between cuts if needed.

Tips for the Best Salted Caramel Apple Pie Bars

Choose firm apples: They hold their shape as they bake and won’t turn mushy.
Slice apples evenly: Thin, uniform slices cook at the same rate and make the bars easier to cut.
Press the crust firmly: A compact crust is less likely to crumble when you lift and slice the bars.
Don’t skip the cooling time: The filling sets as it cools, helping the squares hold their shape.
Use flaky sea salt sparingly: A little adds a savory contrast to the caramel without making the bars salty.
Add caramel just before serving: This keeps the topping neat and prevents the crumble from becoming sticky.
Line the pan with parchment: Leave an overhang so you can lift the whole slab out easily.

The Best Apples to Use

Use apples that are firm and flavorful. Good choices include:

Granny Smith
Honeycrisp
Pink Lady
Braeburn
Fuji
Gala

Granny Smith apples add a tart note that pairs especially well with the sweet caramel. For a sweeter filling, use Honeycrisp, Fuji, or Gala. You can also combine a tart apple with a sweet one for a balanced flavor.

Can I Use Store-Bought Caramel Sauce?

Yes. A good-quality jarred caramel sauce works well. Warm it briefly if it’s too thick to drizzle.

If using salted caramel sauce, taste it before adding flaky sea salt. You may need less salt on top.

Delicious Variations

Pecan Caramel Apple Pie Bars

Add ½ cup chopped pecans to the oat crumble for extra crunch and a nutty flavor.

Apple Crisp Bars

Increase the oats to 1½ cups and skip the caramel drizzle for a simpler apple crisp-style bar.

Maple Apple Bars

Replace 2 tablespoons of the brown sugar in the apple filling with maple syrup. Reduce the lemon juice slightly so the filling doesn’t become too wet.

Cranberry Apple Bars

Toss ½ cup dried cranberries with the apple mixture for a sweet-tart variation that’s especially nice for holiday gatherings.

Gluten-Free Apple Pie Bars

Use a measure-for-measure gluten-free flour blend for the crust, filling, and crumble. Check that the oats are certified gluten-free.

Extra-Spiced Apple Bars

Add a pinch of ground ginger or allspice to the apple filling for deeper fall flavor.

Can I Make Them Ahead?

Yes. Bake and cool the bars a day ahead, then cover the pan and refrigerate. Add the caramel drizzle and flaky salt shortly before serving.

For the cleanest slices, chill the bars before cutting. Let them sit at room temperature for about 15 minutes before serving if you prefer a softer texture.

Storage

Because the filling contains fresh fruit, store the bars in an airtight container in the refrigerator for up to 5 days.

For the best texture, place parchment between layers if stacking. The topping may soften slightly in the refrigerator.

Can You Freeze Salted Caramel Apple Pie Bars?

Yes. Freeze the bars without the caramel drizzle for up to 2 months. Let them cool completely, slice them, and store in a freezer-safe container with parchment between layers.

Thaw overnight in the refrigerator. Add the caramel and flaky salt shortly before serving.

Frequently Asked Questions

Why are my bars falling apart?

They may have been sliced before cooling completely, or the crust may not have been pressed firmly enough. Let the bars cool until fully set, and use the parchment overhang to lift them from the pan.

Do I have to peel the apples?

Peeling is recommended for a softer, more pie-like filling. You can leave the peel on if you prefer more texture.

How do I know when the apples are done?

The topping should be golden, and a knife should slide into the apple layer with little resistance.

Can I use quick oats?

Old-fashioned rolled oats give the crumble more texture. Quick oats can be used, but the topping may be softer and less chunky.

Can I serve these warm?

Yes, but let them cool enough to set first. Warm bars will be softer and may not cut as neatly. Serve them with a scoop of vanilla ice cream for a dessert-style treat.

Can I use salted butter?

Yes. Reduce or omit the added salt in the crust and use only a small pinch in the filling.

Can I double the recipe?

Yes. Bake it in two 9 × 13-inch pans for the most even results. If using a larger pan, check the crust and topping as they bake because the thickness may change.

Pro Tips

Press the shortbread crust firmly into the pan, slice the apples evenly, and let the bars cool completely before cutting. Use a sharp knife for clean squares, then finish with caramel and flaky salt just before serving.
