Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour
  • ¾ cup (150g) granulated sugar
  • ½ cup packed (100g) light brown sugar
  • 1 cup (2 sticks/226g) unsalted butter, cold and cubed
  • 1 tsp ground cinnamon
  • 1 tsp lemon zest
  • ½ tsp salt
  • 3 medium ripe nectarines, pitted and sliced (about 2 cups/300g)
  • 1 ½ cups (225g) fresh blueberries
  • ¼ cup (50g) granulated sugar
  • 2 tbsp cornstarch
  • 1 tbsp fresh lemon juice

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan or line it with parchment paper, leaving some overhang for easy removal.
  2. In a large bowl, combine 2 cups (250g) of the all-purpose flour, ½ cup (100g) granulated sugar, ½ cup (100g) light brown sugar, ½ teaspoon salt, and ground cinnamon. Mix evenly.
  3. Cut in the cold, cubed butter using a pastry cutter or fingers until the mixture resembles coarse crumbs with some pea-sized pieces, about 3-5 minutes.
  4. Press two-thirds of the crumble mixture firmly into the bottom of the prepared pan. Bake for 15 minutes until it just starts turning golden.
  5. While the crust bakes, prepare the fruit filling by tossing sliced nectarines and blueberries with ¼ cup (50g) granulated sugar, 2 tablespoons cornstarch, 1 tablespoon fresh lemon juice, and 1 teaspoon lemon zest until evenly coated.
  6. Remove the crust from the oven and spread the fruit filling evenly over the hot crust.
  7. Sprinkle the remaining crumble mixture over the fruit without pressing it down.
  8. Bake for 35-40 minutes until the topping is golden brown and the fruit is bubbling. Tent with foil if the topping browns too quickly.
  9. Cool completely on a wire rack for 1-2 hours to set properly. Optionally chill in the fridge to speed up cooling.
  10. Slice into bars using a sharp serrated knife and enjoy.

Notes

Keep the butter cold to achieve a flaky texture. Pre-bake the crust to avoid sogginess. Toss fruit gently to prevent excess juice. Tent with foil if topping browns too fast. Cool bars completely before slicing to prevent falling apart. Variations include gluten-free flour, vegan butter substitutes, and adding nuts or vanilla extract.
