Ingredients

Scale
  • 2 cups all-purpose flour
  • 1 cup old-fashioned rolled oats
  • 1 cup brown sugar, packed
  • 2 teaspoons ground cinnamon
  • 1/2 teaspoon salt
  • 3/4 cup unsalted butter, melted
  • 1 teaspoon vanilla extract
  • 4 large fresh peaches (about 2 lbs), peeled and diced (or frozen, thawed and drained)
  • 1/4 cup brown sugar
  • 2 tablespoons cornstarch
  • 1 tablespoon lemon juice
  • 1/2 teaspoon ground cinnamon
  • 3/4 cup powdered sugar
  • 23 tablespoons milk (any kind)
  • 1/2 teaspoon vanilla extract
  • Pinch of salt (optional, for glaze)

Instructions

  1. Preheat oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper, leaving overhang for easy lifting.
  2. In a large bowl, whisk together flour, oats, brown sugar, cinnamon, and salt. Pour in melted butter and vanilla extract. Stir until mixture resembles coarse crumbs. Reserve 1 cup of this mixture for the topping.
  3. Firmly press the remaining crisp mixture into the bottom of the prepared pan to form an even layer.
  4. In another bowl, gently toss diced peaches with brown sugar, cornstarch, lemon juice, and cinnamon until glossy and syrupy.
  5. Spoon the peach mixture evenly over the pressed base, spreading out any clumps.
  6. Sprinkle the reserved 1 cup of crisp mixture evenly over the peaches. Press down very gently.
  7. Bake for 35–40 minutes, or until the top is golden brown and the filling is bubbly around the edges.
  8. Transfer the pan to a wire rack and let cool at least 1 hour before glazing.
  9. In a small bowl, whisk together powdered sugar, milk, vanilla extract, and a pinch of salt until smooth and pourable.
  10. Drizzle the glaze over cooled bars. Use the parchment overhang to lift bars out of the pan, then slice into 16 squares or bars.

Notes

For gluten-free bars, use a 1:1 gluten-free flour blend and certified gluten-free oats. Vegan adaptations are easy with plant-based butter and milk. Let bars cool completely before slicing for clean edges. Add chopped nuts to the topping for extra crunch, or swap peaches for other fruits like berries or apples. Store bars in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days.
