Ingredients
  

Crust & Crumb Topping

  • 1 cup 125 g all-purpose flour
  • ½ cup plus 1 tablespoon old-fashioned rolled oats divided
  • ⅓ cup packed light or dark brown sugar
  • 1 teaspoon ground cinnamon
  • ⅛ teaspoon salt
  • 10 tablespoons unsalted butter cold and cubed
  • ¼ cup sliced almonds optional

Peach Filling

  • 1 large egg
  • ½ cup granulated sugar
  • 1½ tablespoons all-purpose flour
  • 1 teaspoon pure vanilla extract
  • ¼ teaspoon almond extract
  • ½ teaspoon fresh lemon zest
  • 2½ cups chopped fresh peaches

Vanilla Icing

  • ½ cup confectioners' sugar
  • 1 tablespoon milk or heavy cream
  • ½ teaspoon pure vanilla extract

Instructions
 

  • Preheat the oven to 350°F (177°C).
  • Line an 8-inch square baking pan with parchment paper, leaving an overhang for easy removal.
  • In a food processor or large bowl, combine the flour, ½ cup oats, brown sugar, cinnamon, and salt.
  • Add the cold butter and pulse or cut it into the flour mixture until coarse crumbs form.
  • Reserve 1 cup of the crumb mixture in a small bowl and stir in the remaining tablespoon of oats and sliced almonds if using.
  • Firmly press the remaining crumb mixture into the prepared baking pan.
  • Bake for 15 minutes.
  • Remove the crust and increase the oven temperature to 375°F (191°C).
  • In a large bowl, whisk together the egg, granulated sugar, flour, vanilla extract, almond extract, and lemon zest.
  • Gently fold in the chopped peaches.
  • Pour the peach filling evenly over the warm crust.
  • Sprinkle the reserved crumb topping evenly over the filling.
  • Bake for 40–42 minutes, or until the topping is lightly golden.
  • Cool in the pan for 1 hour.
  • Refrigerate for at least 2 hours until completely chilled.
  • Whisk together the confectioners' sugar, milk, and vanilla until smooth.
  • Drizzle the icing over the chilled Peach Pie Crumb Bars.
  • Slice into squares and serve.

Notes

  • Almond extract enhances the peach flavor beautifully but can be omitted if preferred.
  • The bars become even more flavorful after chilling overnight.
  • Store chilled until ready to serve for the best texture.
  • These bars are ideal for summer parties, picnics, and bake sales.
