Ingredients
Method
- Heat the oven to 350°F (175°C). Line a 9-by-13-inch baking pan with parchment paper, leaving a 2-inch overhang on the long sides to make lifting easy.
- In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, and salt. Pour in the melted butter, egg, and vanilla, then stir until a thick, slightly sticky dough forms.
- Set aside one-third of the dough for the topping. Press the remaining dough into the prepared pan in an even layer, then bake for 10 to 12 minutes until just lightly golden.
- In a separate bowl, gently toss the diced peaches with the cornstarch, remaining 1/4 cup sugar, lemon juice, and cinnamon until the fruit is evenly coated.
- Spread the peach filling evenly over the par-baked crust, then crumble the reserved dough over the top in small, uneven clumps.
- Bake for 35 to 40 minutes, until the topping is golden and the fruit filling bubbles around the edges. Place the pan on a wire rack.
- Let the bars cool completely in the pan for at least 2 hours. For cleaner cuts, refrigerate for 1 hour, then lift out with the parchment and cut into squares.

Notes
If using canned peaches, pick ones packed in juice and cut the sugar in the filling to 2 tablespoons.
For a firmer crumb, refrigerate the assembled bars for 15 minutes before baking if your kitchen is warm.
Swap the cinnamon for 1/4 teaspoon nutmeg or cardamom for a different flavor twist.
Store leftovers in an airtight container in the fridge for up to 4 days.
These bars freeze beautifully: wrap each square individually and freeze for up to 2 months.
Let the bars cool at least 2 hours before slicing, or they will fall apart.
Serve at room temperature or slightly chilled with vanilla ice cream.
