Method
Prepare pan and crust
- Preheat the oven to 350°F and line a 9x13 pan with parchment paper, leaving overhang for easy lifting.
- Pulse the all-purpose flour, powdered sugar, salt, and cold butter until the mixture resembles coarse crumbs, then press firmly into the bottom of the pan.
- Bake the crust for 15 minutes, until it is just set and lightly dry on the surface.
Fill and top
- Toss the diced peaches with granulated sugar, cornstarch, cinnamon, nutmeg, and lemon juice until evenly coated.
- Spread the peach mixture over the warm crust in an even layer.
- Combine the flour, sugar, and cold butter for the crumble until it forms coarse crumbles, then scatter it over the peach layer.
Bake, cool, and slice
- Bake for 35 to 40 minutes at 350°F, until the topping is golden and the filling is bubbling around the edges.
- Cool completely before lifting from the pan and slicing into bars, so the filling sets and the layers hold together.
Notes
For the cleanest bars, cool fully at room temperature (about 1–2 hours), then lift using the parchment overhang. Store covered in the refrigerator up to 4 days; freeze baked bars for up to 2 months. For a less-sweet option, reduce granulated sugar in the filling by 2 to 3 tablespoons and add a pinch more cinnamon to keep the peach flavor bright.
