Ingredients

Scale
  • 1 3/4 cups old-fashioned oats
  • 1 cup all-purpose flour (or almond flour for gluten-free)
  • 3/4 cup packed brown sugar (light or dark)
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1 cup unsalted butter, melted (or coconut oil for dairy-free)
  • 4 cups peeled and sliced fresh peaches (about 4 medium peaches) or 2 cans (15 oz each) peach slices, drained
  • 1/4 cup granulated sugar
  • 1 tablespoon lemon juice
  • 2 tablespoons cornstarch
  • 1/2 teaspoon ground nutmeg (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan lightly with butter or non-stick spray.
  2. In a large bowl, combine oats, flour, brown sugar, cinnamon, and salt. Pour in the melted butter and stir until evenly moistened and crumbly. Divide this mixture into two parts: one for the base and one for the topping.
  3. In a separate bowl, toss sliced peaches with granulated sugar, lemon juice, cornstarch, and nutmeg (if using). Stir gently to coat the fruit without breaking it up.
  4. Press about two-thirds of the crumble mixture firmly into the bottom of the prepared baking pan to form an even base.
  5. Spread the peach filling evenly over the crust in a thin layer.
  6. Sprinkle the remaining crumble mixture evenly over the peaches.
  7. Bake for 40-45 minutes until the topping is golden brown and the peach filling is bubbly.
  8. Cool completely on a wire rack before cutting into bars.

Notes

If topping browns too quickly, tent loosely with foil halfway through baking. Drain canned peaches well to avoid soggy bars. Cool bars completely before cutting to prevent crumbling. Toast oats lightly for extra nuttiness and crunch. Cornstarch is essential to thicken the filling and prevent runniness.
