Ingredients

Scale
  • 1 cup (227 g) unsalted butter, browned and cooled slightly
  • 1 ½ cups (180 g) all-purpose flour
  • ½ cup (50 g) almond flour
  • ¾ cup (150 g) granulated sugar
  • ¼ cup (50 g) brown sugar
  • ½ teaspoon salt
  • 1 teaspoon baking powder
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 3 cups (about 4–5 medium) fresh nectarines, peeled, pitted, and sliced
  • 1 tablespoon lemon juice
  • 2 tablespoons cornstarch
  • ¼ cup (30 g) sliced or chopped almonds (optional)

Instructions

  1. Brown the Butter: Place 1 cup unsalted butter in a medium saucepan over medium heat. Stir frequently as it melts and foams. After the foam subsides, watch for the butter to turn golden and develop a nutty aroma (about 5-7 minutes). Remove from heat immediately when light brown specks appear. Pour into a bowl to cool slightly but do not let it harden.
  2. Prepare the Shortbread Base: In a large bowl, whisk together 1 ½ cups all-purpose flour, ½ cup almond flour, ½ teaspoon salt, 1 teaspoon baking powder, and ¾ cup granulated sugar. Add the browned butter, 1 large room-temperature egg, and 1 teaspoon vanilla extract. Stir with a spatula until dough starts to come together but remains crumbly. Press about two-thirds of this mixture evenly into the bottom of a greased 9×13-inch pan. Compact firmly using fingers or the back of a spoon. Bake for 15 mi…
  3. Make the Nectarine Filling: While the base bakes, toss 3 cups sliced nectarines with 1 tablespoon lemon juice, 2 tablespoons cornstarch, and ¼ cup brown sugar in a bowl until juicy but not watery.
  4. Assemble the Bars: Remove the baked shortbread base from the oven. Spread the nectarine filling evenly over it. Crumble the remaining shortbread dough on top in chunks. If desired, sprinkle ¼ cup sliced almonds over the crumble.
  5. Bake for Final Time: Return the pan to the oven and bake for another 25-30 minutes at 350°F (175°C) until the top is golden and crisp and the filling is bubbling. Tent loosely with foil if topping browns too fast.
  6. Cool and Serve: Let the bars cool completely in the pan on a wire rack to allow the filling to set. Cut into squares or rectangles and enjoy.

Notes

Use medium heat and stir constantly when browning butter to avoid burning. Compact the shortbread base firmly to prevent crumbling. Add extra cornstarch (up to 1 tablespoon) if nectarines are very juicy to avoid soggy bars. Chilling dough before pressing is optional but helps with tenderness. For gluten-free, substitute all-purpose flour with a gluten-free blend containing xanthan gum. For dairy-free, use vegan butter but note flavor changes.
