Ingredients

Scale
  • 2 1/2 cups all-purpose flour (about 315g)
  • 1 cup granulated sugar (200g)
  • 1 cup unsalted butter, cold and cubed (227g)
  • 1 cup almonds, chopped or slivered (about 120g)
  • 1 tsp ground cinnamon
  • 1/2 tsp salt
  • 4 cups mixed berries (fresh or frozen, about 600g) – blueberries, raspberries, blackberries
  • 2/3 cup granulated sugar (130g)
  • 2 tbsp fresh lemon juice
  • 3 tbsp cornstarch
  • 1 tsp vanilla extract
  • Additional 1/2 cup flour (63g) for filling

Instructions

  1. Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. In a large bowl, whisk together 2 cups (252g) of the flour, sugar, cinnamon, salt, and chopped almonds.
  3. Add the cold, cubed butter. Using a pastry cutter or food processor, pulse or cut the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized bits (about 3–5 minutes). Do not overmix.
  4. Press half of this crumb mixture into the bottom of the prepared pan, flattening it evenly. Bake for about 15 minutes until edges start to turn golden. Let cool slightly.
  5. In a separate bowl, toss the mixed berries with sugar, lemon juice, cornstarch, vanilla extract, and the remaining 1/2 cup (63g) of flour.
  6. Spread the berry filling evenly over the partially baked crust without pressing down or mashing the berries.
  7. Sprinkle the remaining crumb mixture over the berry layer, crumbling gently to cover but leaving some gaps.
  8. Bake the bars for 35–40 minutes until the topping is golden and the berry filling is bubbling. Tent with foil if streusel browns too quickly.
  9. Cool completely on a wire rack for about 2 hours to set the filling. Chill in the fridge for an hour before slicing for best results.
  10. Slice into squares or rectangles using a sharp knife warmed under hot water and wiped dry for clean edges.

Notes

Keep butter cold to ensure crumbly texture. Do not overmix crumble to maintain pea-sized butter lumps. Adjust sugar based on berry tartness. Use parchment paper for easy cleanup and non-stick. Slice bars only after they have completely cooled or chilled for clean cuts. Add extra cornstarch if berries are very juicy to prevent sogginess.
