These old-fashioned apple squares have a simple shortbread base topped with a juicy apple filling and a buttery sweet crumb topping that contrasts nicely and makes it a crowd-pleaser! They can be frozen after baked, and most components can be made ahead. A great and easier alternative to making apple pie.
A great alternative to pie
Apple is the ingredient that my family asks for when it comes to desserts. Skip the chocolate; they'll thank you for it. And what is baking but a way of showing our love, right? So apples it is.
This recipe for apple squares is a twist on the first recipe I learned from my grandmother (her apple crisp), but with a buttery shortbread base that makes all the difference.
It's simple and versatile, as the crumble can be dressed up with nuts and oats, and the apples can be paired with other citrus and different spices. You can find the variations further along this post.
My favorite part about these crumb bars is that they're easier to make than a traditional apple pie. The bar format eliminates the need for a pie crust, and the crumb topping is simpler to prepare than a double crust.
Also, bars are easy to transport and serve, so they're great for gatherings, picnics, potlucks and road trips. Make the portions larger or smaller, depending on how you serve them.

FAQ
What type of apples are best for apple pie bars?
Choose apples that hold their shape during baking and balance sweetness and tartness. The most popular choice and the ones we use are Granny Smith, the green ones. Other options might be Honeycrisp, Fuji, Braeburn or a mix of different varieties for a more complex flavor.
Can you make apple pie crumb bars in advance?
Yes, you can make apple bars in advance. Bake and cool them completely, then store them according to the instructions above. If you want to serve them warm, you can reheat in the oven at a low temperature or briefly in the microwave.
Ingredient list
For the shortbread crust:
- Unsalted butter.
- All-purpose flour.
- White, granulated sugar.
For the apple filling:
- Apples: I use granny smith apples exclusively (the green ones, my absolute favorites for baking due to their tartness). They bring some acid to the mix that complements the overall sweetness of the cake. And they hold their shape and don't turn mushy in the oven. If you have another favorite that you usually bake with (pink lady, fuji, gala, Honeycrisp apples), by all means, use it.
- Brown sugar: light or dark.
- Ground cinnamon.
For the crumb topping:
- Unsalted butter.
- White, granulated sugar.
- Brown sugar: light or dark.
- All-purpose flour.

Variations & substitutions
- Use brown butter for the shortbread base. It adds depth and a unique sweet vanilla flavor.
- Add berries: a half cup of raspberries or blueberries pair very well with the apple filling.
- Add oats to the crumble: substitute up to half the flour for oats. It can make the topping crisper and add another layer of texture.
- Nuts: add ⅓ cup chopped nuts to the crumb topping for extra crunch and flavor. Pecans, walnuts, or almonds work well with the apple filling.
- Glazed apple pie bars: drizzle a simple glaze on top of the cooled bars for extra sweetness. A maple glaze also works well.
- Oatmeal crust: replace ⅓ of the flour in the crust with old-fashioned oats for a heartier texture.
Steps to make apple pie crumb bars
Shortbread base
Mix ingredients in a large bowl and then put in the baking pan. Distribute it throughout the bottom.
Press it with your hands until it's all compacted and there are no crumbly parts.
You can add a pinch of salt, spices, citrus zest, and other flavorings.
Prick & bake
Prick it with a fork and freeze it before pre-baking it. Bake it for 15 minutes, until it's starting to dry and puff.
These steps will make it crisper and less soggy once the apple filling is added.
The apples
Use your favorite baking apples. I use Granny Smith apples, the green ones.
You can slice them thicker or thinner. Very thin slices (cut with a mandoline) will bake softer than thicker ones.
Crumb topping
You can integrate it by hand, with a fork or pastry cutter.
Make-ahead: it can be made in advance and frozen for a month. Or kept in the refrigerator for a week. Add it directly.
Top the apples with the crumble mixture. It will cover them almost completely. Lightly press with your hand so the topping is a little compacted.
Baking
The top with dry and turn golden brown. The juices will bubble around the edges.
Pierce the apples with a knife to check for softness before removing from the oven.
Serving apple bars
They are great at room temperature, but warm with a scoop of vanilla ice cream makes them irresistible, according to everyone around me!
- A dollop of cream (straight from the container or whipped) also works.
- Caramel sauce or dulce de leche: some of it drizzled over the ice cream makes for a fantastic dessert!
Kitchen Notes
- Organization: read the recipe first and ensure you have ingredients at the correct temperature, utensils and equipment needed, and enough workspace. This will make the process so much easier.
- Baking time: consider that all ovens and pans are different, even if they look similar. The baking time in my recipes is as accurate as it can be, but it might take you more or less time. You can use a thermometer(like the OXO oven thermometer) to check that your oven is at the right temperature. I recommend you keep track of how your oven works and what tiny details you might need to adjust.
- Apples: peel and cut at the last minute to avoid them turning brown as much as you can. Use a mandoline for thin slices (like the ones in this post) or a kitchen knife to cut thicker ones.
- Make-ahead: the base and the crumble can be made ahead and frozen for a month or kept in the fridge for a week.
- Storage:
Room temperature: store the apple bars in an airtight container for up to 2 days.
Refrigerator: they keep well for up to a week. Cover with plastic wrap or an airtight container to avoid odors and dryness.
Freezer: individually wrap the bars in plastic wrap and store them in a sealed freezer bag for a month.
To thaw: place overnight in the refrigerator or leave at room temperature, uncovered for a few hours. You might want to warm them in a medium oven before serving, especially with ice cream. - Flavorings: use other spices and/or citrus zest to change the flavor slightly.

Ingredients
For the shortbread base:
- ½ cup unsalted butter, at room temperature
- ¼ cup white sugar
- 1 cup all-purpose flour
- pinch of salt
For the crumble:
- 1 cup all-purpose flour
- ⅓ cup white sugar
- ⅓ cup light brown sugar
- ½ cup unsalted butter, diced and cold
For the apples:
- 5 cups Granny Smith apples, about 5, peeled, cored, and sliced
- ¼ cup white or brown sugar
- 1 teaspoon ground cinnamon
- 2 tablespoons lemon juice
Instructions
For the shortbread base:
- With a wooden spoon or electric hand mixer on low, cream ½ cup unsalted butter with ¼ cup white sugar until smooth.
- Add a pinch of salt and 1 cup all-purpose flour in two parts, combining well. Do not overmix. It will be crumbly.
- Grease an 8-inch square pan. Line with a strip of parchment paper covering the bottom and two of the sides.
- Press the dough evenly to cover the bottom. Lightly flour the tips of your fingers if needed.
- Prick the bottom crust with a fork and freeze for 30 minutes.
- Preheat the oven to 350ºF (180°C).
- Bake for about 15 minutes, until it’s dry in parts and starts to color lightly. Reserve on a wire rack.
For the crumble:
- Mix 1 cup all-purpose flour, ⅓ cup white sugar and ⅓ cup light brown sugar in a medium bowl.
- Add ½ cup unsalted butter in pieces and integrate them with a fork, a pastry cutter, or your hands (my choice) until you have a clumpy crumble.
- Keep refrigerated.
For the apples:
- Peel and core 5 medium/large apples.
- Cut in half and then in half again to have 4 wedges. Remove the seeds and hard center parts. Slice with a kitchen knife. You should have 5 cups Granny Smith apples5 cups sliced apples. Transfer them to a large bowl.
- Sprinkle ¼ cup white or brown sugarand 1 teaspoon ground cinnamonon top and drizzle with 2 tablespoons lemon juice. Stir to coat and transfer to the prepared pan.
- Alternatively, layer the apple slices on the shortbread base, sprinkle with cinnamon and sugar, and drizzle with lemon juice. It's a lot of apples, but they shrink considerably during baking.
To assemble:
- Top the crust with the apple mixture, spreading to cover it all.
- Top the apples with the crumble mixture. It will cover them almost completely. Lightly press with your hand so the topping is a tad compacted.
- Bake for about 40 minutes, until the top is golden and the apples can be easily pierced with a knife.
- Let cool on a wire rack.
- Serve at room temperature or warm with a scoop of ice cream or whipped cream.

Hi Paula,
I'm wondering - why don't you add the cinnamon mixture to the apples rather than sprinkle it on top of the apples once placed on top of the crust?
Any reason I couldn't do that?
Thanks
Paula Montenegro says
Hi Patti! No reason. You can mix it with the apples. I'll add a note to the recipe card about it.
