Ingredients

Scale
  • 1 ½ cups all-purpose flour (190g)
  • 1 cup old-fashioned rolled oats (90g)
  • ¾ cup packed brown sugar (150g)
  • 10 tablespoons unsalted butter, cold and cubed (140g)
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon salt
  • 4 cups mixed stone fruit (peaches and plums), peeled and sliced (600g)
  • ⅓ cup granulated sugar (65g)
  • 1 tablespoon fresh lemon juice
  • 2 tablespoons cornstarch
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan lightly with butter or non-stick spray.
  2. In a large bowl, combine 1 ½ cups all-purpose flour, 1 cup rolled oats, ¾ cup packed brown sugar, 1 teaspoon cinnamon, and ¼ teaspoon salt. Toss to mix evenly.
  3. Add 10 tablespoons cold, cubed butter. Using a pastry cutter, two forks, or your fingertips, work the butter into the dry ingredients until the mixture looks like coarse crumbs with some pea-sized bits.
  4. Reserve 1 ½ cups of the crumble mixture and set aside in the fridge for the topping later.
  5. Press the remaining crumble mixture firmly into the bottom of the prepared pan, creating an even layer. Bake this crust for 15 minutes until lightly golden and set.
  6. While the crust bakes, combine 4 cups sliced stone fruit, ⅓ cup granulated sugar, 1 tablespoon fresh lemon juice, 2 tablespoons cornstarch, and 1 teaspoon vanilla extract in a medium bowl. Toss gently to coat the fruit evenly.
  7. Pour the fruit filling evenly over the partially baked crust. Spread gently with a spatula, being careful not to disturb the crust layer.
  8. Sprinkle the reserved crumble topping evenly over the fruit layer, covering it completely but not packing it down.
  9. Bake the assembled bars for 35-40 minutes until the top is golden brown and the fruit filling is bubbly around the edges. If the topping browns too quickly, loosely tent with foil.
  10. Cool completely on a wire rack for at least 2 hours so the filling sets up nicely.
  11. Cut into bars using a sharp knife, wiping it clean between cuts for neat edges. Serve at room temperature or slightly warmed.

Notes

Use firm but ripe stone fruit to avoid watery filling. Chill butter before cutting into dry ingredients for best crumble texture. Press crust firmly to prevent bars from falling apart. Pre-bake crust to avoid sogginess. If topping browns too fast, tent with foil. For gluten-free, substitute flour with almond flour and use certified gluten-free oats. Vegan option: replace butter with coconut oil or vegan butter and sugar with maple syrup.
