Ingredients

For the Crust & Crumble

• 1 ½ cups all-purpose flour
• ½ cup granulated sugar
• ¼ teaspoon salt
• ½ teaspoon vanilla extract
• ¾ cup unsalted butter (cold, cubed)
• ½ cup shelled pistachios (roughly chopped)

For the Blackberry Filling

• 2 cups fresh blackberries
• ⅓ cup granulated sugar
• 1 tablespoon lemon juice
• 2 teaspoons cornstarch
• 1 teaspoon lemon zest

Optional Topping

• Powdered sugar for dusting
• Extra chopped pistachios

Step-by-Step Cooking Guide

Step 1 – Prepare the Oven and Pan

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper for easy removal.

Step 2 – Make the Crust Mixture

In a mixing bowl, combine flour, sugar, and salt. Add cold butter and mix using your fingers or a pastry cutter until the mixture becomes crumbly. Stir in vanilla extract and chopped pistachios.

Step 3 – Form the Base

Press about two-thirds of the mixture firmly into the bottom of the prepared pan to create the crust.

Step 4 – Prepare the Blackberry Filling

In another bowl, gently mix blackberries, sugar, lemon juice, lemon zest, and cornstarch until well combined.

Step 5 – Assemble the Bars

Spread the blackberry mixture evenly over the crust. Sprinkle the remaining crumble mixture on top.

Step 6 – Bake

Bake for 35–40 minutes or until the top is golden and the filling is bubbling.

Step 7 – Cool and Slice

Allow the bars to cool completely before slicing into squares. Dust with powdered sugar if desired.
