Ingredients
  

Crust & Streusel Topping
  • 1 cup all-purpose flour spooned and leveled into the measuring cup to avoid packing
  • ½ cup old-fashioned rolled oats whole oats not instant or quick-cook; divided — reserve 1 tablespoon for topping
  • 1 tablespoon old-fashioned rolled oats reserved from above; stirred into the streusel topping separately
  • ⅓ cup packed light brown sugar dark brown sugar works equally well for a deeper molasses note
  • 1 teaspoon ground cinnamon adds warmth to both the crust and topping layers
  • ⅛ teaspoon fine sea salt balances the sweetness; do not skip
  • 10 tablespoon unsalted butter cold and cubed cold butter is essential for a crumbly flaky texture — do not soften
  • ¼ cup sliced almonds optional adds a light crunch to the streusel; omit for a nut-free version
Peach Filling
  • 1 large egg cold (helps bind the filling and gives it a light custardy texture)
  • ½ cup granulated white sugar sweetens the filling; adjust slightly if peaches are very ripe
  • 1½ tablespoon all-purpose flour thickens the juices released by the peaches during baking
  • 1 teaspoon pure vanilla extract or vanilla bean paste vanilla bean paste adds visible specks and deeper flavor
  • ¼ teaspoon almond extract a small amount enhances the natural peach flavor dramatically
  • ½ teaspoon fresh lemon zest from about half a lemon; brightens and balances the sweetness
  • 2½ cups fresh peach chunks chopped about 400g; peeled and roughly ½-inch pieces — do not use canned
Vanilla Icing
  • ½ cup powdered confectioners' sugar sifted for a lump-free, smooth drizzle
  • 1 tablespoon heavy cream or whole milk heavy cream gives a richer glossier icing
  • ½ teaspoon pure vanilla extract or vanilla bean paste ties the icing flavor back to the filling

Method
 

  1. Preheat your oven to 350°F (177°C) and line an 8-inch square baking pan with parchment paper, leaving a generous overhang on all four sides for easy removal later.
  2. Combine the flour, the ½ cup portion of rolled oats, brown sugar, cinnamon, and salt in a food processor or large bowl, then pulse or whisk until evenly mixed.
  3. Add the cold cubed butter and pulse in the food processor or work it in with a pastry cutter until the mixture forms coarse, pea-sized clumps that hold together when pinched between your fingers.
  4. Transfer approximately 1 cup of the crumb mixture into a separate small bowl, stir in the reserved 1 tablespoon of oats and the sliced almonds if using, and set this topping aside.
  5. Press the remaining crumb mixture firmly and evenly into the base of the prepared pan, then bake the crust for 15 minutes; once done, remove from the oven and raise the oven temperature to 375°F (191°C).
  6. While the crust is still hot, prepare the filling by whisking together the egg, granulated sugar, flour, vanilla, almond extract, and lemon zest in a large bowl until smooth and combined.
  7. Fold the fresh peach chunks gently into the egg mixture until all the fruit is evenly coated, then immediately pour the filling over the hot crust — do not let the filling sit or the peaches will release too much liquid.
  8. Scatter the reserved streusel topping evenly over the peach filling, distributing the oats and almonds across the surface.
  9. Bake at 375°F for 40 to 42 minutes, or until the streusel topping is lightly golden and the filling appears set with no visible jiggle in the center.
  10. Remove the pan from the oven and allow the bars to cool completely on a wire cooling rack for 1 hour, then cover and transfer to the refrigerator to chill for at least 2 hours before slicing.
  11. Once fully chilled, lift the bars out of the pan using the parchment overhang and place on a cutting board; slice into squares using a sharp knife, wiping the blade clean between each cut for neat edges.
  12. Whisk the confectioners' sugar, cream or milk, and vanilla together in a small bowl until smooth and pourable, then drizzle generously over the sliced bars just before serving.

Notes

These bars taste even better the next day once the filling has fully set and the flavors have had time to meld. Make them ahead for summer potlucks, peach season picnics, or any moment that calls for something warm, fruity, and a little bit golden.
