  • 1 cup all-purpose flour or gluten-free flour
  • 1/2 cup unsalted butter cold and cubed
  • 1/4 cup granulated sugar
  • 1/4 teaspoon salt
  • 1 large egg yolk do not use the whole egg
  • 2-4 tablespoons ice water use cold water
  • 2 cups fresh blackberries or raspberries/blueberries
  • 1/2 cup granulated sugar adjust as necessary
  • 1 tablespoon lemon juice fresh juice is best
  • 2 tablespoons cornstarch
  • 1/2 cup light brown sugar or granulated sugar
  • 1 teaspoon baking powder
  • 1 cup pistachios shelled and unsalted, or other nuts
  • 1/2 cup unsalted butter cold and cubed
  • 1 large egg
  • 1 teaspoon vanilla extract

Equipment

  • 9x13 inch baking pan
  • Mixing bowls
  • Medium saucepan
  • Pastry cutter or fork
  • Spatula
  • Whisk
  • Parchment paper

Method
 

  1. Preheat oven to 350°F (175°C) and grease a 9x13 inch baking pan. Line with parchment paper for easy removal.
  2. In a large bowl, whisk together flour, sugar, and salt until evenly distributed.
  3. Cut in cold butter using a pastry cutter or fingers until mixture resembles coarse crumbs with pea-sized pieces.
  4. Add egg yolk and 2 tablespoons ice water, mixing with fork until dough begins to come together. Add more water 1 tablespoon at a time if needed.
  5. Press crust mixture firmly and evenly into bottom of prepared pan. Pre-bake for 15-20 minutes until lightly golden. Remove and cool slightly.
  6. In a medium saucepan, combine blackberries and sugar over medium heat. Cook for 5-7 minutes, stirring frequently, until berries break down and release juices.
  7. Stir in lemon juice and cornstarch. Cook for another 1-2 minutes until mixture thickens and becomes glossy.
  8. Remove from heat and let cool slightly before assembling.
  9. In a separate bowl, whisk together brown sugar, baking powder, and flour for topping.
  10. Cut in cold butter until mixture becomes crumbly.
  11. Mix in egg and vanilla extract until just combined. Do not overmix.
  12. Gently fold in pistachios until distributed throughout the crumbly mixture.
  13. Pour slightly cooled blackberry filling over pre-baked crust, spreading evenly with spatula.
  14. Sprinkle pistachio topping across entire surface, pressing down gently to adhere without squishing filling.
  15. Bake for 30-35 minutes until topping is golden brown and filling is bubbling around edges.
  16. Let bars cool completely in pan for at least 1-2 hours before cutting to allow filling to set properly.

Notes

  • Store at room temperature in airtight container for up to 3 days
  • Refrigerate for up to 5 days, though crust may soften slightly
  • Freeze individual bars wrapped tightly for up to 2 months
  • Can prepare crust and topping 24 hours ahead and refrigerate
  • Blackberry filling can be made up to 3 days in advance
  • Frozen blackberries work but drain excess liquid and add extra cornstarch
  • Use cold butter for flakiest texture
  • Don't overmix any layers or they'll become tough
  • Line pan with parchment paper for easiest removal
  • Swap berries or nuts based on preference
