# What You Need:
→ Pistachio Shortbread Base
01 - 1 cup unsalted shelled pistachios
02 - 1 1/3 cups all-purpose flour
03 - 1/2 cup granulated sugar
04 - 1/4 teaspoon salt
05 - 1/2 cup cold unsalted butter, cubed
→ Blackberry Filling
06 - 2 cups fresh or thawed frozen blackberries
07 - 1/3 cup granulated sugar
08 - 1 tablespoon lemon juice
09 - 1 tablespoon cornstarch
→ Streusel Topping
10 - 1/2 cup all-purpose flour
11 - 1/4 cup rolled oats
12 - 1/3 cup brown sugar
13 - 1/4 cup cold unsalted butter, cubed
14 - 1/3 cup shelled pistachios, roughly chopped
# How to Make It:
01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a food processor, pulse pistachios until finely ground. Add flour, sugar, and salt; pulse to combine. Add cold butter and pulse until mixture resembles coarse crumbs. Evenly press the dough into the prepared pan.
03 - Bake the base for 12 to 15 minutes until it turns lightly golden. Remove from oven and set aside.
04 - In a mixing bowl, combine blackberries, granulated sugar, lemon juice, and cornstarch. Gently mash berries to release some juices.
05 - In a separate bowl, mix flour, oats, brown sugar, and chopped pistachios. Add cold butter and work it in with fingers until the mixture turns crumbly.
06 - Spread the blackberry filling evenly over the baked shortbread base. Sprinkle the streusel topping uniformly over the blackberries.
07 - Return to oven and bake for 20 to 22 minutes, until topping is golden brown and filling is bubbling.
08 - Allow bars to cool completely in the pan. Lift out using parchment paper, cut into 16 bars, and serve.
# Expert Tips:
01 -
- The layers look like bakery magic, but they come together with just a few bowls and your hands.
- You can make them with whatever berries or nuts you have, and they’ll always impress as the prettiest treat on the table.
02 -
- If you don't wait for the bars to cool, you'll end up with a gooey mess, not tidy slices.
- Chilling the base briefly before baking makes it extra crisp—I almost skipped this once and regretted it.
03 -
- Grinding the pistachios just right—fine but not pasty—is the secret to melt-in-your-mouth texture.
- A quick blast in the fridge firms up the base so layering is a breeze and the crust comes out crisp.
