Ingredients

Scale
  • 1 ¾ cups (220 g) all-purpose flour
  • ⅓ cup (65 g) granulated sugar
  • ⅓ cup (70 g) light brown sugar
  • ¾ cup (170 g) unsalted butter, browned and cooled
  • ½ tsp salt
  • ¼ tsp baking powder
  • 1 tsp ground cinnamon
  • 4 medium fresh peaches, peeled and diced
  • 1 tbsp lemon juice
  • ⅓ cup (65 g) granulated sugar
  • 1 tbsp cornstarch
  • ¼ tsp ground nutmeg (optional)

Instructions

  1. Brown the butter: Place ¾ cup (170 g) unsalted butter in a medium saucepan over medium heat. Stir frequently as it melts and foams, then begins to brown and smell nutty (about 5-7 minutes). Remove from heat and let cool slightly.
  2. Prepare the crust and crumble: In a large bowl, whisk together 1 ¾ cups (220 g) all-purpose flour, ⅓ cup (65 g) granulated sugar, ⅓ cup (70 g) light brown sugar, ½ tsp salt, ¼ tsp baking powder, and 1 tsp ground cinnamon. Pour in the warm brown butter and mix with a wooden spoon until coarse crumbs form. Reserve about 1 cup for the crumble topping.
  3. Make the peach filling: In a separate bowl, toss 4 peeled and diced peaches with 1 tbsp lemon juice, ⅓ cup (65 g) granulated sugar, 1 tbsp cornstarch, and ¼ tsp nutmeg. Stir gently to combine and let sit for 5 minutes to macerate.
  4. Assemble the bars: Press the larger portion of the crust mixture firmly into the bottom of a greased 9×9-inch (23×23 cm) pan to form an even layer (about 10 minutes work). Spread the peach filling evenly over the crust, then sprinkle the reserved crumb topping over the fruit.
  5. Bake: Place the pan in a preheated oven at 350°F (175°C) and bake for 35-40 minutes, or until the topping is golden and peaches are bubbling around the edges. If the top browns too fast, loosely cover with foil after 25 minutes.
  6. Cool and serve: Let the bars cool in the pan for at least 30 minutes to set. Cut into squares and enjoy warm or at room temperature.

Notes

Watch the butter closely while browning to avoid burning. Use the bottom of a measuring cup to press crust evenly. Lemon juice brightens the peach filling and balances sweetness. For cleaner slices, chill bars for an hour before cutting. Peeling peaches is optional if thin-skinned. Frozen peaches can be used if thawed and drained well.
