These apple pie bars with shortbread crust have a buttery base, tender cinnamon apples, and a brown sugar crumble you can stir together with a fork. The dough presses straight into the pan, so there is no rolling pin to find or pie edge to crimp.
This batch of apple pie bars with shortbread crust fits an 8-inch square pan and makes 16 little dessert bars. Cook the diced apples while the crust bakes, then add the topping and return the pan to the oven. The longest part is letting everything cool enough for neat slices, which makes these a handy dessert to bake the day before you need them.

Why these apple pie bars with shortbread crust work
- A firm shortbread base: Prebaking gives the crust a head start before the fruit goes on top.
- Apple filling you can check: A quick skillet cook lets you soften the fruit and thicken its juices before assembling.
- Simple crumble: Flour, brown sugar, cinnamon, salt, and melted butter make an oat-free topping.
- A manageable batch: Sixteen small squares suit a family dessert or a modest get-together.
If you want an oat topping and caramel sauce, try the site’s salted caramel apple pie bars. This version keeps its focus on the shortbread crust and cinnamon apple layer.
Ingredients for apple pie bars with shortbread crust
You will use butter and flour in more than one layer. Measure each group separately so the topping ingredients do not accidentally end up in the crust. Spoon flour into the cup and level it off, or use the gram amounts below.
Shortbread crust
- 1/2 cup unsalted butter: 113 g; melted and cooled slightly.
- 1/4 cup granulated sugar: 50 g.
- 1 teaspoon vanilla extract.
- 1/4 teaspoon fine salt.
- 1 1/4 cups all-purpose flour: 150 g; spooned and leveled.
Apple filling
- 4 cups apples: about 500 g after peeling and coring; cut into 1/4-inch dice; about 4 medium apples.
- 1 tablespoon unsalted butter.
- 1/4 cup light brown sugar: packed; 53 g.
- 1 tablespoon lemon juice.
- 1 teaspoon ground cinnamon.
- 1/8 teaspoon ground nutmeg.
- 1/8 teaspoon fine salt.
- 1 tablespoon cornstarch.
- 1 tablespoon cold water.
Crumble topping
- 3/4 cup all-purpose flour: 90 g; spooned and leveled.
- 1/4 cup light brown sugar: packed; 53 g.
- 1/2 teaspoon ground cinnamon.
- 1/8 teaspoon fine salt.
- 4 tablespoons unsalted butter: 57 g; melted and cooled slightly.
Which apples should I use?
Granny Smith gives the filling a tart edge; Honeycrisp brings more sweetness. Either works here, or use a mix. Choose firm apples, and avoid fruit that is mealy or bruised. Four medium apples are only a shopping estimate: aim for 4 cups of prepared 1/4-inch dice, about 500 grams.
Wash the apples under cool running water before peeling or cutting them. University of Minnesota Extension recommends washing produce before preparation and advises against using soap, detergent, or bleach.
How to make apple pie bars with shortbread crust
Plan your time: Allow about 30 minutes of preparation, 48 to 55 minutes of oven time, and about 2 hours to cool. The skillet cooking overlaps the crust bake. The recipe card uses the upper bake estimate for a total of 3 hours 25 minutes; an optional chill adds 30 minutes.
1. Prepare the pan
Heat the oven to 350°F with a rack in the middle. Lightly grease an 8-inch square metal pan at least 2 inches deep. Line it with parchment, leaving overhang on two sides. Wash the apples under cool running water before peeling, coring, and cutting into 1/4-inch dice.
2. Make and prebake the crust
Stir the 1/2 cup melted butter, granulated sugar, vanilla, and 1/4 teaspoon salt together. Fold in 1 1/4 cups flour just until a soft dough forms. Press evenly across the bottom of the pan, paying attention to the corners. Bake for 18 to 20 minutes, until the surface looks dry and the edges are light golden. Keep the oven at 350°F.
3. Cook and thicken the apples
While the crust bakes, melt 1 tablespoon butter in a 10-inch skillet over medium heat. Add the diced apples, 1/4 cup brown sugar, lemon juice, 1 teaspoon cinnamon, nutmeg, and 1/8 teaspoon salt. Cook, stirring often, for 8 to 12 minutes, until the apples are almost tender and most loose juice has evaporated. If they stick before softening, add 1 tablespoon water and keep cooking. Mix the cornstarch with the measured 1 tablespoon cold water until smooth. Stir into the apples and cook for 1 to 2 minutes, until the juices bubble and become glossy and thick enough to coat the fruit, with no watery pool. Remove from the heat.
4. Mix the crumble
Stir the 3/4 cup flour, remaining 1/4 cup brown sugar, 1/2 teaspoon cinnamon, and 1/8 teaspoon salt together. Add the 4 tablespoons melted butter and stir with a fork until uneven crumbs form. Squeeze a few portions together for larger crumbs.
5. Assemble and bake
Spread the thickened apples evenly over the warm prebaked crust. Scatter the crumble on top without pressing it down. Bake for 30 to 35 minutes, until the topping is golden, the filling bubbles around the edges, and an apple piece near the center is tender when pierced with a small knife. If the top browns early, tent loosely with foil and continue baking until those cues are met.
6. Cool and cut
Cool completely in the pan on a wire rack, about 2 hours. Lift out by the parchment and cut into a 4-by-4 grid for 16 bars with a sharp knife, wiping it between cuts. For firmer slices, refrigerate the cooled slab for 30 minutes before cutting.
Tips for apple pie bars with shortbread crust
- Use the specified pan: A light-colored metal 8-inch square pan gives a useful reference for the baking times. A 9-inch pan makes thinner layers and needs earlier checking.
- Keep the crust even: Use the flat bottom of a measuring cup to press the dough, without building a thick ridge along the sides.
- Look at the filling: It should be glossy and cling to the apples before it goes into the pan. A watery pool needs more skillet time.
- Leave the crumble loose: A mixture of small and larger crumbs gives the top texture; pressing it flat makes it denser.
- Cool before lifting: The fruit and butter need time to firm up. If you want a warm serving, cut the cooled bars first and warm individual pieces.
Substitutions and simple variations
Salted butter: You can use it in place of unsalted butter. Omit the added salt from all three layers; the final saltiness depends on the brand.
Spices: Leave out the nutmeg if you prefer, keeping the cinnamon amounts the same. For a ginger note, add 1/8 teaspoon ground ginger to the apple filling.
Different apples: Firm Pink Lady apples are another option. Fruit varies in sweetness and juiciness, so use the skillet cues rather than adding extra sugar or stopping at an exact minute.
Dietary swaps: This recipe contains wheat and milk. Gluten-free flour blends and plant-based butter can change the crust and topping, and those versions need separate testing. Liquid oil is not a direct substitute for the butter.
Storing apple pie bars with shortbread crust
Once your apple pie bars with shortbread crust have cooled, refrigerate them in an airtight container for up to 4 days. Separate stacked layers with parchment. The crumble will soften somewhat as it sits, so enjoy it soon after baking if that texture matters most to you.
For longer storage, wrap individual cooled bars and place them in a freezer-safe container for up to 2 months for best quality. Thaw in the refrigerator overnight. Warm a single bar on a microwave-safe plate in 10-second bursts, or serve it chilled.
To make these ahead, bake the day before, cool, and refrigerate the slab covered in the pan. Cut it before serving. You can also prepare the cooked filling a day ahead, refrigerate it covered, and gently rewarm just until spreadable before assembling.
Troubleshooting apple pie bars
| Problem | Likely cause | What to do |
|---|---|---|
| Soft or soggy base | Underbaked crust or loose apple juices | Prebake until dry and lightly golden at the edges; thicken the filling before layering. |
| Bars fall apart | Cut while warm | Cool completely; add the optional 30-minute chill before cutting. |
| Apples are still firm | Large dice or short skillet cook | Cut evenly to 1/4 inch and cook until almost tender before baking. |
| Topping browns too fast | Hot oven or rack too high | Use the middle rack; tent loosely with foil and continue until the apples are tender. |
| Dry, sandy topping | Too much flour | Spoon and level the flour or weigh 90 g; include all 4 tablespoons of topping butter. |
Frequently asked questions
Can I use canned apple pie filling?
The recipe is written for fresh apples cooked with its measured sugar and thickener. Canned filling has a different sweetness, thickness, and fruit-to-sauce ratio, so it is not a direct measured swap here.
Do I have to prebake the shortbread crust?
Yes. The crust needs its initial 18 to 20 minutes in the oven before the moist apple layer goes on top. Skipping that step changes the finished base.
Can I bake apple pie bars with shortbread crust in glass?
Metal is the reference pan for this recipe. Glass heats differently, so follow the dish manufacturer’s guidance and check the crust and final bake by their visual cues. Timing will need adjustment.
Can I double these apple pie bars with shortbread crust?
Doubling the ingredients is a reasonable starting point for a 9×13-inch metal pan, but that larger batch has not been tested. Check for a dry, lightly golden prebaked crust, then a golden topping, bubbling edges, and tender center apples; expect the timing to change.
Why are these bars taking longer than the listed time?
Ovens, pans, and apple varieties vary. The listed times are estimates. Continue baking until the topping is golden and the apples are tender, using foil if the top is getting too dark.
Can I serve them with ice cream?
Yes. Cut the fully cooled bars first, gently warm individual servings if you like, and add vanilla ice cream just before serving.
