Ingredients

Scale

For the Shortbread Crust & Crumble:

  • 1 1/4 cups (250 g) granulated white sugar
  • 1 tbsp (10 g) lemon zest
  • 1 cup (224 g) unsalted butter, softened
  • 1 tsp vanilla extract
  • 2 1/2 cups (312 g) all purpose flour
  • 3/4 tsp salt

For the Triple Berry Filling:

  • 1 3/4 cups (232 g/8 oz.) fresh raspberries
  • 1 1/2 cups (240 g/8.5 oz.) fresh blueberries
  • 1 3/4 cups (250 g/9 oz.) fresh blackberries
  • 3/4 cup (150 g) granulated white sugar
  • 1/4 cup (32 g) cornstarch
  • 1 tbsp (15 ml) lemon juice

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 375℉ (190℃). Spray a 9×9 inch pan with non-stick spray and line it with parchment paper for easy removal of the bars.
  2. Flavor Sugar with Lemon Zest: In a large bowl, combine the granulated sugar with the lemon zest. Rub them together using your fingertips to release the natural oils and intensify the lemon aroma.
  3. Cream Butter and Sugar: Add the softened butter and vanilla extract to the sugar mixture. Using an electric mixer, cream on high speed for 1-2 minutes until the mixture is very light and fluffy.
  4. Add Flour and Salt: Incorporate the all-purpose flour and salt into the mixture. Mix on low speed just until the dough forms large clumps, being careful not to overmix.
  5. Divide Dough: Separate the dough by setting aside about one-third for the crumble topping and reserving the remaining two-thirds for the crust. For precision, use a kitchen scale to evenly divide the dough.
  6. Chill Crumble Dough: Place the crumble portion of the dough into the refrigerator to chill while you prepare the rest.
  7. Press Crust into Pan: Press the larger portion of the dough evenly into the bottom of the prepared 9×9 inch pan using your hands or a small offset spatula for a smooth finish.
  8. Prepare Berry Filling: In a large bowl, combine fresh raspberries, blueberries, and blackberries. Add granulated sugar, cornstarch, lemon zest, and lemon juice to the berries. Gently toss the mixture with a spatula to coat the berries evenly.
  9. Let Berries Sit: Allow the berry mixture to sit for a few minutes so the cornstarch can start to absorb the juices and thicken the filling slightly.
  10. Assemble Bars: Pour the berry filling over the pressed crust in the pan, spreading it out evenly.
  11. Add Crumble Topping: Remove the chilled crumble dough from the refrigerator and sprinkle it evenly over the berry layer.
  12. Bake: Bake the bars in the preheated oven for 65-70 minutes or until the topping is golden brown and the berry filling is bubbling around the edges.
  13. Cool and Serve: Remove the bars from the oven and place them on a wire rack to cool completely. This step allows the filling to set before cutting into 16 bars. Enjoy your delicious treat!

Notes

  • Use fresh, ripe berries for the best flavor and texture.
  • If you prefer a more tart filling, reduce the sugar slightly in the berry mixture.
  • Make sure to cool the bars completely before cutting to prevent the filling from oozing out.
  • For easier cleanup, lining the pan with parchment paper is recommended.
  • The bars can be stored in an airtight container in the refrigerator for up to 4 days.
  • Reheat individual bars slightly before serving for a warm dessert experience.
