Ingredients
  

For the Crust and Topping
  • 2.5 cups all-purpose flour Gluten-free flour blend can be used as a substitute.
  • 3/4 cup granulated sugar Adjust based on sweetness preference.
  • 1/2 teaspoon salt Enhances flavors.
  • 1 cup unsalted butter, cold and cubed Cold butter helps create the crumbly texture.
  • 1 teaspoon vanilla extract Use pure vanilla for the best flavor.
  • 1 cup reserved crumble mixture Set aside from the mixture for topping.
For the Peach Filling
  • 4 cups diced peaches Fresh, frozen or drained canned peaches work well.
  • 1 tablespoon lemon juice Brightens the flavor of peaches.
  • 1/4 cup granulated sugar For sweetening the filling.
  • 1 tablespoon cornstarch Thickens the peach mixture.
  • 1/2 teaspoon cinnamon (optional) Adds warmth to the filling.
  • 1/4 teaspoon nutmeg (optional) Enhances flavor complexity.

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C) and line a 9x13-inch baking pan with parchment paper.
  2. In a large mixing bowl, combine the flour, 3/4 cup granulated sugar, and salt.
  3. Add the cold butter cubes and cut them in using a pastry cutter until the mixture resembles coarse crumbs.
  4. Stir in the vanilla extract until just combined.
  5. Press the remaining mixture firmly into the bottom of your prepared pan to create a solid crust.
Prepare the Filling
  1. In a separate bowl, combine your diced peaches with lemon juice, 1/4 cup sugar, cornstarch, and optional cinnamon and nutmeg. Toss gently to coat the peaches evenly.
Assemble and Bake
  1. Spoon the peach mixture evenly over the crust, spreading it out with a spatula.
  2. Sprinkle the reserved crumble mixture over the top.
  3. Bake for 45-50 minutes, or until the top is golden brown and the filling is bubbling.
  4. Allow to cool completely before lifting out using the parchment overhang and slice into 16 squares.

Notes

For best flavor, let your bars rest for a few hours before serving to allow the filling to set. Store in an airtight container for up to 3 days at room temperature, or refrigerate for a week. Freeze for up to 3 months.
