These Apple Pie Bars bring together the comforting flavors of traditional apple pie in an easy-to-serve bar dessert.
Each square features a rich, buttery shortbread crust, a warmly spiced apple filling, and a crumbly oatmeal streusel topping.
The combination creates a satisfying contrast of textures, from the firm, tender base to the soft apples and crisp, golden crumbs on top.
The filling combines Granny Smith and Pink Lady apples for a balance of tartness and natural sweetness.
Granulated sugar, ground cinnamon, and a touch of optional nutmeg enhance the fruit’s flavor, while fresh lemon juice adds brightness.
A small amount of cornstarch helps thicken the apple juices, creating a luscious filling that holds together when the bars are sliced.
Gently cooking the apples before baking softens them and helps develop their classic apple pie flavor.
The shortbread crust is made from butter, granulated sugar, brown sugar, vanilla extract, flour, salt, and cinnamon.
It provides a tender, rich foundation that complements the juicy apples beautifully.
On top, old-fashioned rolled oats, brown sugar, flour, cinnamon, and chilled butter form a generous streusel that bakes into a deliciously crumbly layer.
These bars are an excellent choice for autumn gatherings, holiday dessert tables, family get-togethers, or an everyday sweet treat.
They can be served on their own or paired with a scoop of vanilla bean ice cream for an extra-special dessert.
Although they have several layers, each component is straightforward to prepare, making this recipe a rewarding way to enjoy the familiar taste of homemade apple pie in a convenient bar form.
Classic Apple Pie Streusel Bars
Ingredients
Equipment
Method
- Prepare the Streusel Topping: In a medium mixing bowl, whisk together the rolled oats, packed brown sugar, flour, salt, and cinnamon until evenly combined.
- Incorporate the Butter: Add the chilled, cubed butter to the oat mixture. Cut it into the dry ingredients or work it in with your fingertips until the mixture forms coarse clumps.
- Chill the Streusel: Cover the bowl and refrigerate the topping while preparing the crust and apple filling. The streusel can also be prepared up to one day ahead and kept chilled.
- Combine the Crust Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, salt, and cinnamon. Set the mixture aside.
- Cream the Butter and Sugars: Using a stand mixer fitted with a paddle attachment, beat the softened butter, granulated sugar, and packed brown sugar until the mixture becomes creamy.
- Finish the Crust Dough: Add the vanilla extract and mix to combine. With the mixer running on low speed, gradually add the flour mixture, mixing until the ingredients form a cohesive dough.
- Press the Crust into the Pan: Transfer the dough to a 9 × 13-inch oven-safe baking dish. Press it evenly across the bottom to create the shortbread base. Refrigerate for 20 minutes; do not skip this chilling step.
- Preheat the Oven: Heat the oven to 375°F (approximately 190°C) while the crust chills.
- Prebake the Crust: Bake the chilled shortbread crust for 18 minutes. Remove the dish from the oven and allow the crust to cool while preparing the apple filling. Reduce the oven temperature to 350°F (approximately 175°C).
- Season the Apples: Place the peeled, cored, thinly sliced apples in a large mixing bowl. Add the granulated sugar, ground cinnamon, and optional nutmeg, tossing until the slices are evenly coated.
- Prepare the Thickener: In a small bowl, whisk the lemon juice and cornstarch together until combined. Add this mixture to the seasoned apples and stir to distribute it throughout the filling.
- Cook the Apple Filling: Transfer the apple mixture to a large saucepan and cook over medium heat for 5–8 minutes, stirring occasionally, until the apples begin to soften. Add water as needed to keep the apples from sticking, scorching, or burning in the pan. Avoid overcooking, as the apples will continue to soften in the oven.
- Layer the Apples over the Crust: Spread the cooked apple mixture evenly over the prebaked shortbread crust, distributing the slices across the surface.
- Add the Streusel Topping: Remove the chilled streusel from the refrigerator and scatter it evenly over the apples, covering the filling with the oat mixture.
- Bake the Apple Pie Bars: Place the assembled dish in the oven at 350°F (approximately 175°C) and bake for 30–35 minutes, until the topping is golden and the layers are baked through.
- Cool and Slice: Remove the dish from the oven and allow the bars to cool before cutting. Slice into 12 large bars and serve as they are or alongside vanilla bean ice cream.
Notes
- Apple Selection: Use a combination of Granny Smith and Pink Lady apples for a balance of tartness and sweetness. The recipe calls for 6–8 apples, approximately 3 pounds in total.
- Slice Evenly: Cut the peeled and cored apples into slices about 1/4 inch thick so they soften evenly during cooking and baking.
- Chill the Crust: Refrigerate the pressed shortbread dough for 20 minutes before baking. This step is important for preparing the crust according to the original method.
- Prepare Streusel Ahead: Make the oatmeal streusel up to one day in advance and store it covered in the refrigerator until needed.
- Cook the Apples Briefly: Simmer the apple mixture for 5–8 minutes, just until the slices begin to soften. They will continue cooking in the oven.
- Add Water as Needed: Use up to 1/2 cup of water as necessary during stovetop cooking to prevent the apples from scorching.
- Measure the Thickener Carefully: The 2 tablespoons of cornstarch help the filling set. Combine it with the lemon juice before adding it to the apples for more even distribution.
- Allow Time to Cool: Let the baked bars cool before slicing to help the apple filling settle and make cleaner portions.
- Use the Correct Oats: Old-fashioned rolled oats provide the intended streusel texture. Avoid quick-cooking or instant oats.
Chef’s Secret
For apple pie bars that slice neatly without sacrificing a soft, juicy filling, pay close attention to how much the apples soften before baking.
Cook them over medium heat for just 5–8 minutes, stirring occasionally, until they begin to become tender.
Add water gradually as needed to prevent sticking or scorching, rather than pouring it all in at once.
The goal is to soften the fruit without turning it into applesauce, since the slices will continue cooking in the oven.
Equally important, whisk the cornstarch thoroughly into the lemon juice before mixing it with the apples.
This helps distribute the thickener evenly and encourages the filling to set properly.
Finally, allow the finished bars to cool before slicing so the filling can settle.
Serving Suggestions
Serve these apple pie bars slightly warm or at room temperature for a comforting dessert.
A scoop of vanilla bean ice cream is a particularly good pairing, as its cool, creamy texture complements the buttery shortbread, tender cinnamon apples, and crumbly oatmeal topping.
For an extra finishing touch, sprinkle a little ground cinnamon over the ice cream or add a light dusting of powdered sugar just before serving.
The bars also pair nicely with freshly whipped cream or a spoonful of plain yogurt for a less-sweet accompaniment.
For autumn gatherings, arrange the sliced bars on a serving platter alongside hot coffee, black tea, or warm apple cider.
They make a lovely addition to holiday dessert tables, potlucks, and family celebrations.
Cut them into smaller squares when serving alongside other desserts, or keep the portions generous for a standalone treat.
Conclusion
These Apple Pie Bars combine the familiar flavors of homemade apple pie with the convenience of an easy-to-serve dessert.
A buttery shortbread base, warmly spiced apple filling, and golden oatmeal streusel create a delicious balance of textures in every bite.
