Ingredients
  

For the Crust and Topping
  • 1.5 cups all-purpose flour
  • 1 cup rolled oats
  • 1 cup granulated sugar
  • 0.5 teaspoon baking soda
  • 0.25 teaspoon salt
  • 0.75 cup unsalted butter, melted
For the Peach Filling
  • 4 cups fresh or frozen peaches, sliced if using frozen, do not thaw

  • 2 tablespoons cornstarch
  • 1 tablespoon lemon juice
  • 0.5 teaspoon cinnamon

Equipment

  • 9x13-inch baking pan

Method
 

  1. Preheat your oven to 375°F (190°C). Grease and flour a 9x13 inch baking pan.
  2. In a large bowl, combine the flour, rolled oats, 1 cup granulated sugar, baking soda, and salt for the crust and topping. Pour in the melted butter and mix until combined and crumbly.
  3. Press about two-thirds of the crumble mixture evenly into the bottom of the prepared baking pan to form the crust.
  4. In a separate bowl, gently toss the sliced peaches with 0.5 cup granulated sugar, cornstarch, lemon juice, and cinnamon until evenly coated.
  5. Spread the peach filling evenly over the crust.
  6. Sprinkle the remaining crumble mixture evenly over the peach filling.
  7. Bake for 30-35 minutes, or until the topping is golden brown and the filling is bubbly.
  8. Let the bars cool completely in the pan before cutting into 12 bars.
