Ingredients

1 cup (2 sticks) unsalted butter, softened
1 cup granulated sugar
½ cup light brown sugar, packed
2 large eggs
2 teaspoon vanilla extract
2 ¼ cups all-purpose flour
½ teaspoon baking powder
½ teaspoon salt
1 ¼ cups fresh blackberries (or frozen, thawed and drained)
1 tablespoon cornstarch
2 tablespoon granulated sugar (for blackberry mixture)
¾ cup shelled pistachios, roughly chopped

Directions

Prep Time: 20 min | Cook Time: 35 min | Total Time: 55 min

1. Prepare the Pan & Oven

Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal.

2. Make the Butter Base

In a large bowl, cream together the butter, 1 cup granulated sugar, and brown sugar until light and fluffy (about 2-3 minutes).
Beat in eggs, one at a time, then stir in vanilla extract.

3. Mix the Dry Ingredients

In a separate bowl, whisk together flour, baking powder, and salt.
Add the dry mixture to the wet ingredients, mixing just until combined.

4. Prepare the Blackberry Filling

In a medium bowl, gently toss blackberries with 1 tablespoon cornstarch and 2 tablespoons granulated sugar. Set aside.

5. Assemble the Bars

Spread about ⅔ of the dough evenly into the bottom of the prepared pan.
Spoon the blackberry mixture evenly over the base.
Dollop the remaining dough over the berries (it won't cover completely).
Sprinkle chopped pistachios evenly over the top.

6. Bake

Bake for 35-38 minutes, or until the top is lightly golden and set. The center should not jiggle when gently shaken.
Cool completely in the pan before lifting out and slicing into bars.

Notes

If using frozen blackberries, make sure to thaw and drain well to avoid excess moisture.
Chop pistachios coarsely for a better crunch and more attractive look.
For easy slicing, chill bars in the fridge for 1 hour after cooling to room temperature.

Variations

Lemon Blackberry Bars: Add 1 tablespoon fresh lemon zest into the dough for a zesty twist.
Gluten-Free Version: Use a 1:1 gluten-free all-purpose flour blend.
Mixed Berry Bars: Substitute part of the blackberries with blueberries or raspberries.
