Ingredients

Scale
  • 2 ½ cups (315 g) all-purpose flour
  • ¾ cup (150 g) granulated sugar
  • 1 cup (227 g) unsalted butter, cold and cubed
  • ½ teaspoon salt
  • 1 teaspoon vanilla extract
  • 3 cups (450 g) fresh or frozen mixed berries (strawberries hulled and sliced, blueberries, raspberries)
  • ½ cup (100 g) granulated sugar
  • 1 teaspoon lemon zest
  • 1 tablespoon fresh lemon juice
  • 2 tablespoons cornstarch
  • ¼ teaspoon ground cinnamon (optional)
  • 1 cup (125 g) all-purpose flour
  • ½ cup (110 g) brown sugar
  • ½ cup (113 g) unsalted butter, cold and cubed
  • ½ cup (50 g) slivered almonds, lightly toasted
  • ½ teaspoon ground cinnamon
  • Pinch of salt

Instructions

  1. Prepare the shortbread base (15 minutes): In a large bowl, whisk together 2 ½ cups (315 g) flour, ¾ cup (150 g) sugar, and ½ teaspoon salt. Add 1 cup (227 g) cold, cubed unsalted butter. Use a pastry cutter or fork to cut the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces. Stir in 1 teaspoon vanilla extract. Press this mixture evenly into the bottom of a greased 9×13-inch pan. Place in the fridge while you prepare the filling.
  2. Make the berry filling (10 minutes): In a medium bowl, combine 3 cups (450 g) mixed berries, ½ cup (100 g) sugar, 1 teaspoon lemon zest, 1 tablespoon lemon juice, 2 tablespoons cornstarch, and ¼ teaspoon cinnamon. Gently toss until berries are evenly coated but not crushed. Set aside to macerate while you prepare the streusel.
  3. Prepare the almond streusel topping (10 minutes): In another bowl, mix 1 cup (125 g) flour, ½ cup (110 g) brown sugar, ½ teaspoon cinnamon, a pinch of salt, and ½ cup (50 g) toasted slivered almonds. Add ½ cup (113 g) cold, cubed butter and cut it in until the mixture forms coarse crumbs. It should feel crumbly but hold together slightly when pressed.
  4. Assemble and bake (30-35 minutes): Remove the pan from the fridge. Spread the berry filling evenly over the chilled shortbread base. Sprinkle the almond streusel topping generously over the berries, covering most of the surface. Bake in a preheated oven at 350°F (175°C) for 30-35 minutes, or until the streusel is golden brown and the berry filling is bubbling at the edges.
  5. Cool and slice (30 minutes): Let the bars cool completely in the pan on a wire rack—this helps the filling set and makes slicing easier. For cleaner edges, chill in the fridge for another 30 minutes before cutting into squares or rectangles. Use a sharp knife and wipe it between cuts if needed.

Notes

Keep the butter cold to ensure a crumbly texture. Toast slivered almonds before adding to streusel for enhanced flavor. If streusel browns too fast, tent with foil halfway through baking. Let bars cool completely before slicing to avoid messy cuts. Frozen berries should be thawed and drained to prevent soggy crust. For gluten-free, substitute all-purpose flour with a 1-to-1 gluten-free blend. For dairy-free, use vegan buttery spread instead of butter.
