PEACH PIE CRUMBLE BARS Recipe

I packed everything I love about peach pie and peach crumble into one bar: buttery shortbread, juicy peaches, and golden oatmeal crunch. The result is a peach dessert that disappears from the pan faster than I can slice it.

I’m obsessed with these Peach Pie Crumble Bars because I get all the good parts of peach pie without committing to a whole pie situation. Buttery shortbread on the bottom, juicy fresh peaches in the middle, and that chunky rolled oats crumble on top that I will absolutely pick at before slicing.

And yes, I love the messier corner pieces most. These bars taste like peak peach season with a little crunch, a little syrupy fruit, and enough buttery bite to keep me going back for another square.

Maybe two. No regrets, just sticky fingers and an empty pan staring back at me.

Ingredients

• Flour gives the bars structure, so they don’t fall apart in your hand.
• Granulated sugar keeps the crust sweet and gives the peaches that jammy vibe.
• Salt balances everything, because sweet stuff needs a little backup.
• Cold butter makes the crust and crumble tender, buttery, and slightly crisp.
• Egg helps hold the base together, like a quiet little glue.
• Vanilla adds cozy bakery flavor without trying too hard.
• Fresh peaches bring juicy sweetness, color, and that summer dessert feeling.
• Brown sugar adds deeper, caramel-like sweetness to the fruit and topping.
• Lemon juice keeps the peaches bright, not flat or overly sweet.
• Cornstarch thickens the filling, so it’s gooey instead of runny.
• Rolled oats bring chewy crunch and make the crumble feel extra homemade.
• Cinnamon adds warmth, like peach pie met a cozy sweater.
• Plus, coarse sugar gives the top a pretty sparkle and little crunch.

Ingredient Quantities

• 2 cups all purpose flour
• 2/3 cup granulated sugar
• 1/2 teaspoon salt
• 1 cup unsalted butter cold and cubed (2 sticks)
• 1 large egg
• 1 teaspoon vanilla extract
• 4 cups fresh peaches peeled and sliced (about 4 to 5 medium)
• 1/3 cup granulated sugar
• 2 tablespoons packed brown sugar
• 1 tablespoon lemon juice
• 1 tablespoon cornstarch
• pinch of salt
• 1 1/2 cups rolled oats
• 1 1/2 cups all purpose flour
• 3/4 cup packed brown sugar
• 1/2 cup granulated sugar
• 1 teaspoon ground cinnamon
• 1 cup unsalted butter cold and cubed (2 sticks)
• coarse sugar for sprinkling on top optional

How to Make this

1. Preheat oven to 350 F and line a 9 by 13 inch baking pan with parchment paper leaving an overhang for easy removal.

2. Make the shortbread base: in a bowl combine 2 cups all purpose flour, 2/3 cup granulated sugar and 1/2 teaspoon salt. Cut in 1 cup cold cubed unsalted butter until mixture resembles coarse crumbs, then stir in 1 large egg and 1 teaspoon vanilla extract until dough comes together.

3. Press the dough evenly into the prepared pan to form the base. Use the bottom of a measuring cup to compact it for an even layer.

4. Partially bake the base for 12 to 15 minutes until it just begins to set and the edges are slightly pale golden. Remove from oven and leave oven on.

5. Meanwhile prepare the peach filling: toss 4 cups peeled and sliced fresh peaches with 1/3 cup granulated sugar, 2 tablespoons packed brown sugar, 1 tablespoon lemon juice, 1 tablespoon cornstarch and a pinch of salt until evenly coated.

6. Spread the peach mixture evenly over the warm parbaked shortbread base.

7. Make the oatmeal crumble topping: in a bowl combine 1 1/2 cups rolled oats, 1 1/2 cups all purpose flour, 3/4 cup packed brown sugar, 1/2 cup granulated sugar and 1 teaspoon ground cinnamon. Cut in 1 cup cold cubed unsalted butter until the mixture forms coarse crumbs and some pea sized pieces remain.

8. Scatter the oatmeal crumble evenly over the peaches. If desired, sprinkle coarse sugar over the top for extra crunch and sparkle.

9. Bake the assembled bars at 350 F for 35 to 40 minutes, or until the topping is golden brown and the peach filling is bubbling. If the edges brown too quickly, tent with foil for the last 10 minutes.

10. Cool completely in the pan on a wire rack, then refrigerate for at least 1 hour to set before using the parchment overhang to lift out and cut into bars. Store chilled or at room temperature for up to 3 days.

PEACH PIE CRUMBLE BARS Recipe Substitutions and Variations

• All purpose flour: Swap for equal-weight whole wheat pastry flour for a nuttier, tender crust, or use a 1:1 gluten free all purpose blend if gluten-free is needed.
• Unsalted butter: Use cold coconut oil in the same amount for a dairy-free option, or use salted butter and reduce the added salt by about 1/4 teaspoon.
• Large egg: Replace with a flax “egg” (1 tablespoon ground flaxseed mixed with 3 tablespoons water, let sit 5 minutes) for an egg-free binder.
• Cornstarch: Substitute arrowroot powder in a 1:1 ratio to thicken the peach filling, or use tapioca starch if you prefer a slightly chewier filling.

Pro Tips

1. Keep the butter cold and handle the dough quickly. Cold butter gives a flakier, sturdier shortbread and crumble; work until you have coarse crumbs with some pea sized pieces, then stop. If the kitchen is warm, chill the pressed base 10 minutes before parbaking to prevent spreading.

2. Control excess juice from the peaches. Use slightly underripe but ripe-flavored fruit when possible, and toss slices with the cornstarch and lemon juice at least 10 minutes before assembling so the starch can start drawing out and binding juices. If your peaches are extremely juicy, add an extra 1 to 2 teaspoons of cornstarch.

3. Protect the edges and the topping for even browning. Bake on the middle rack and rotate the pan once during baking. If the edges brown faster than the center, tent loosely with foil for the last 10 minutes. Placing the baking pan on a rimmed sheet helps catch any bubbling fruit juices and keeps your oven clean.

4. Chill before cutting and serve with care. Let the bars cool completely, then refrigerate at least an hour so the filling firms up and slices stay neat. Warm slightly before serving if you prefer softer texture, or top with a scoop of ice cream for a great contrast.
