Peach Pie Bars Recipe

These buttery, jammy peach pie bars feature a melt-in-your-mouth shortbread crust and a spiced fresh peach filling, topped with a golden brown crumble that rivals any traditional pie.

Why This Recipe Works:

• One-Dough Wonder: The buttery shortbread mixture does double duty as both the sturdy bottom crust and the crispy streusel topping, cutting prep time in half.
• Cornstarch Gelatinization: Using cornstarch instead of flour creates a clear, glossy fruit filling that holds its shape beautifully when sliced into clean bars.
• Balanced Moisture: Pre-tossing the peaches with a touch of lemon juice and sugar draws out just enough liquid to prevent a soggy bottom crust.

I still remember the humid August afternoon I tried to slice a warm, freshly baked classic peach pie for my sister's backyard bridal shower. The entire middle collapsed into a sad, soupy puddle on the counter.

It was a total disaster.

The culprit was excess moisture, a common issue when baking with stone fruits that have high water content. I tested this recipe with four different thickeners, and standard all-purpose flour failed every single test because it clumped up and created a cloudy, pasty gel instead of letting the bright fruit shine.

Cornstarch is hands down the absolute perfect solution here. It binds the juices beautifully without making the filling gummy.

By using a single dough for both the crust and the crumble topping, you save time and avoid washing extra bowls. You simply press the buttery base into the pan and scatter the rest over the fruit.

Bear with me here, because the salt choice actually matters. I always use Diamond Crystal kosher salt to balance the sweet peaches.

They get delightfully chewy.

If you love this format, you should also try my strawberry cheesecake bars or my rustic cherry peach brown betty with crunchy pecan crumble. Trust me on this one, it is incredibly forgiving and perfect for potlucks.

Ingredients

• 1 cup (225g) unsalted butter, melted
• 1/2 cup (100g) granulated sugar
• 1/4 cup (50g) light brown sugar, packed
• 1 teaspoon vanilla extract
• 2 1/2 cups (312g) all-purpose flour
• 1 teaspoon Diamond Crystal kosher salt (or 1/2 teaspoon Morton's kosher salt)
• 4 cups fresh peaches, peeled and sliced (about 4-5 medium peaches)
• 2 tablespoons fresh lemon juice
• 1/4 cup (50g) granulated sugar (for the filling)
• 1 tablespoon cornstarch
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg

Directions

1. Preheat your oven to 375°F (190°C). Line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal later.
2. In a large bowl, whisk together the melted butter, 1/2 cup granulated sugar, brown sugar, and vanilla extract until fully combined and smooth.
3. Stir in the all-purpose flour and kosher salt. Mix with a wooden spoon or your hands until a soft, clumpy dough forms.
4. Reserve 1 cup of the dough for the crumble topping. Press the remaining dough firmly and evenly into the bottom of the prepared baking pan to form the crust.
5. In a medium bowl, gently toss the sliced peaches with the lemon juice, 1/4 cup granulated sugar, cornstarch, cinnamon, and nutmeg until the peaches are evenly coated.
6. Arrange the peach slices in an even layer over the unbaked shortbread crust.
7. Crumble the reserved 1 cup of dough evenly over the top of the peach layer, leaving some larger clumps for texture.
8. Bake for 40 to 45 minutes, or until the top crumble is golden brown and the peach filling is bubbling at the edges.
9. Remove from the oven and let cool completely in the pan on a wire rack before lifting out with the parchment paper and slicing into bars.

Notes

• Salt Conversion: This recipe specifies Diamond Crystal kosher salt. If you are using Morton's kosher salt, reduce the amount to 1/2 teaspoon to avoid an overly salty crust.
• The Science of Cornstarch: Cornstarch requires heat to activate its thickening power. Ensure the peach filling is visibly bubbling at the edges before removing the bars from the oven, which guarantees the starch has gelatinized and set.
• Workflow Warning: Keep a close eye on the oven during the last 10 minutes of baking. If the crumble topping is browning too quickly before the filling bubbles, tent the pan loosely with aluminum foil.
• Storage Behavior: These bars will soften slightly after a day in the fridge as the crust absorbs moisture from the peaches. If you prefer a crispier crust, serve them on the day they are baked.

Serving Suggestions

These bars are incredibly versatile and can be served warm, at room temperature, or chilled straight from the fridge. Enhance the dessert experience with these simple pairings:

• Serve warm with a generous scoop of vanilla bean ice cream.
• Drizzle with a quick powdered sugar glaze or a bit of healthy cream cheese Greek yogurt frosting.
• Pair with a refreshing glass of iced hibiscus lemonade on a hot afternoon.
• Dust lightly with powdered sugar just before slicing and serving.
• Top with a dollop of homemade whipped cream and a sprig of fresh mint.

Storage and Reheating

Store any leftover bars in an airtight container in the refrigerator for up to 5 days. Because of the natural moisture in the peaches, the shortbread crust will soften slightly over time, turning delightfully chewy.

If you prefer them warm, simply pop a bar into the toaster oven at 350°F for about 5 minutes. This helps crisp up the buttery crumble topping again.

Do not microwave them.

Microwaving turns the beautiful shortbread base into a sad, mushy sponge. For long-term storage, you can freeze the sliced bars on a baking sheet before wrapping them individually in plastic wrap and storing them in a freezer bag for up to 3 months.

Ingredient Substitutes

If you need to adapt this recipe for dietary needs or pantry limitations, here are a few reliable swaps:

1. Peaches: If fresh peaches aren't in season, you can use frozen peaches (thawed and drained well) or even canned peaches, similar to how we use them in our classic peach pie.
2. All-Purpose Flour: To make these gluten-free, use a high-quality 1-to-1 gluten-free baking flour blend, or check out our guide on gluten-free peach muffins with almond flour and maple syrup for alternative flour inspiration.
3. Brown Sugar: You can substitute coconut sugar or additional granulated sugar if you run out of light brown sugar.
4. Cornstarch: Arrowroot powder or tapioca starch can be used in a 1:1 ratio if you have a corn allergy.

I hope these bars bring a little bit of sunny, late-summer joy to your kitchen table. Let me know in the comments if you ended up eating them warm straight out of the pan with a spoon—no judgment here, because I absolutely did.
