Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking dish.
- Combine all-purpose flour, granulated sugar, and salt in a bowl. Incorporate the cold butter until coarse crumbs form. Add egg yolk and ice water to form a dough. Press into the prepared pan and pre-bake for 15-20 minutes until golden.
- In a saucepan over medium heat, combine blackberries and sugar, stirring until juices are released. Add lemon juice and cornstarch; cook until thickened, about 1-2 minutes.
- In a bowl, whisk together brown sugar, baking powder, and flour. Cut in the cold butter. Mix in the egg and vanilla, then fold in pistachios.
- Pour the cooled blackberry mixture over the crust. Sprinkle the pistachio topping on top and press down gently. Bake for 30-35 minutes until golden and bubbling.
- Let the bars cool in the pan for 1-2 hours, then slice into squares for serving.
