Easy Peach Crumb Bars with Buttery Crust
A rustic two-layer bar cookie with fresh peaches sandwiched between buttery, crumbly dough. The combination of tender fruit filling and textured topping creates a dessert that's both satisfying and approachable. Slightly underripe peaches provide structure and tang balanced by warm cinnamon and bright lemon juice. The crust uses cold butter worked into flour to achieve distinct pea-sized clumps, delivering a tender crumb rather than dense cake. These bars suit home bakers seeking impressive yet forgiving results without lamination or precise timing. Serve at room temperature with coffee or ice cream, or pack for picnics and potlucks. What sets this version apart is the processor method for effortless crust-making and the pressed-dough technique that eliminates rolling, shaping, or blind baking.

- 1 tsp baking powder
- 1 tsp kosher salt
- ½ tsp ground cinnamon
- 1 cup unsalted butter, cold, diced
- 1 large egg, slightly beaten
Instructions
- 1
Preheat oven to 375 degrees F. Spray or grease a 9 by 13 inch pan.
- 2
Combine diced peaches with lemon juice, sugar, and cornstarch in a bowl. Set aside.
- 3
In a food processor, combine flour, sugar, baking powder, salt, and cinnamon. Add cold diced butter and pulse until butter forms pea-sized clumps.
- 4
With processor running, slowly add beaten egg and process until mixture becomes crumbly dough without appearing dry.
- 5
Press half the dough firmly into the prepared pan to form the bottom crust.
- 6
Spread peach mixture evenly over the dough.
- 7
Sprinkle remaining dough evenly over peaches and press down slightly.
- 8
Bake for 35 to 45 minutes until bottom crust is golden brown and top shows slight golden-brown color.

Cool completely before cutting into bars.
Tips
Use slightly underripe peaches to prevent filling from turning soupy during baking. Overripe fruit releases excess liquid and can make the bottom crust soggy despite the cornstarch.
Keep butter at refrigerator temperature until the moment you add it to the food processor. Warm butter will not create distinct clumps, resulting in a dense, heavy crust instead of light and tender crumb.
Cool bars completely before cutting; cutting while warm causes peach filling to stick to the knife blade and the bars to crumble. A chilled bar cuts clean and holds its shape.
Good to Know
Cover and refrigerate up to 4 days. Room-temperature storage acceptable for 1 day in cool conditions.
Dough can be prepared and pressed into pan up to 4 hours ahead. Cover and refrigerate. Top with peaches and crumb topping, then bake as directed.
Serve at room temperature. Pair with vanilla ice cream, whipped cream, or Greek yogurt. Coffee or iced tea complements the peach and cinnamon flavors.
Common Mistakes
Do not use ripe or overripe peaches to avoid a runny, soupy filling that soaks into the crust.
Do not warm butter before processing to avoid losing the pea-sized texture that creates a tender, flaky crust.
Do not cut bars while warm to avoid filling sticking to the knife and bars falling apart.
Substitutions
thaw and drain well to remove excess water; flavor slightly less bright
FAQ
Can I use canned or frozen peaches instead of fresh?
Yes. Use frozen peaches thawed and drained well to remove excess liquid. Canned peaches work but may be softer and sweeter; drain syrup and reduce added sugar to 1/4 cup. Both yield slightly less vibrant flavor than fresh.
Can I freeze peach crumb bars?
Yes. Cool completely, then freeze in airtight container up to 3 months. Thaw at room temperature 2 to 3 hours before serving. Texture remains tender. Do not freeze unbaked dough-filled bars.
What if the bottom crust stays soggy after baking?
Your peaches likely released excess moisture. Use underriper peaches next time and increase cornstarch to 4 teaspoons. If bottom is pale, extend baking time by 5 to 10 minutes until golden, checking at 40 minutes.
