Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour
  • ¾ cup (150g) granulated sugar
  • ½ cup (110g) packed brown sugar
  • 1 cup (225g) unsalted butter, browned and cooled slightly
  • 1 tsp ground cinnamon (optional)
  • ¼ tsp salt
  • 4 cups (about 6 medium) fresh ripe peaches, peeled and sliced
  • ⅓ cup (65g) granulated sugar
  • 1 tbsp fresh lemon juice
  • 2 tbsp cornstarch
  • 1 tsp vanilla extract

Instructions

  1. Brown the Butter: In a medium saucepan over medium heat, melt 1 cup (225g) unsalted butter. Stir frequently and watch carefully as it foams and then starts to brown (around 5-7 minutes). You’ll see little brown specks and smell a nutty aroma. Remove from heat and pour into a heatproof bowl to cool slightly.
  2. Prepare the Crumble Base: In a large mixing bowl, whisk together 2 ½ cups (315g) all-purpose flour, ¾ cup (150g) granulated sugar, ½ cup (110g) packed brown sugar, 1 tsp ground cinnamon, and ¼ tsp salt. Slowly add the browned butter, stirring with a wooden spoon or spatula until the mixture forms coarse crumbs. It should hold together if squeezed but remain crumbly. Set aside about 1 ½ cups (for topping) in a separate bowl.
  3. Make the Peach Filling: Peel and slice peaches (about 4 cups or 6 medium peaches). In the same saucepan used for butter, combine sliced peaches, ⅓ cup (65g) granulated sugar, 1 tbsp fresh lemon juice, 2 tbsp cornstarch, and 1 tsp vanilla extract. Cook over medium heat for 5 minutes, stirring constantly, until the mixture thickens and becomes glossy. Remove from heat and let cool slightly.
  4. Assemble Bars: Press the larger portion of the crumble base evenly into the bottom of your 9×13-inch baking pan. Pour the peach filling evenly over the crust. Then sprinkle the reserved crumble topping evenly over the peaches.
  5. Bake: Place in a preheated oven at 350°F (175°C) and bake for 40-45 minutes. The topping should be golden brown and the peach filling bubbling around the edges.
  6. Cool and Serve: Allow the bars to cool completely in the pan on a wire rack (about 1 hour). This helps the filling set so you get clean slices. Cut into squares and serve.

Notes

If the crumble browns too fast, tent loosely with foil halfway through baking. Add up to 1 tbsp extra cornstarch if peaches are very juicy to prevent soggy bars. Brown butter carefully on medium heat and remove immediately when nutty aroma appears to avoid burning. Peeling peaches can be easier by blanching in boiling water for 30 seconds then plunging into ice water. Cool bars completely before slicing for clean cuts.
