Blackberry Pistachio Dream Bars Ingredients
For the Crust

• Sugar – Sweetens the shortbread. Brown sugar can add depth to flavors.
For the Filling
• Blackberries – Main flavor component, offering tartness. Fresh or frozen can be used, though frozen should be drained to minimize moisture.

Step‑by‑Step Instructions for Blackberry Pistachio Dream Bars
Step 1: Prepare the Crust
Begin by preheating your oven to 350°F (175°C). In a mixing bowl, cream together ½ cup of softened butter and ¼ cup of sugar until light and fluffy. Gradually mix in 1 cup of all-purpose flour until combined. Press this mixture firmly into the bottom of a greased 8×8-inch baking pan, creating an even layer. Bake the crust for 10-15 minutes, or until it’s golden brown, and let it cool slightly.
Step 2: Make the Filling
While the crust cools, prepare the blackberry filling. In a medium saucepan, combine 2 cups of blackberries, 2 tablespoons of sugar, 1 tablespoon of cornstarch, and 1 tablespoon of lemon juice. Cook over medium heat, stirring gently, until the mixture simmers and thickens, about 5-7 minutes. You want it to bubble up and become glossy. Once ready, remove it from the heat and set aside to cool a bit.
Step 3: Prepare the Topping
In a separate bowl, prepare the crumble topping. Mix together ½ cup of chopped pistachios, ½ cup of rolled oats, ¼ cup of brown sugar, and ¼ cup of all-purpose flour. To bind the dry ingredients together, drizzle in ¼ cup of melted butter. Stir until well combined; the mixture should look crumbly. This pistachio crumble will provide a delicious crunch to your Blackberry Pistachio Dream Bars.
Step 4: Assemble the Bars
Once your blackberry mixture has cooled slightly, spoon the filling evenly over the pre-baked crust. Spread it out gently with a spatula to create an even layer. Next, sprinkle the pistachio crumble topping generously over the blackberry filling, ensuring it’s evenly distributed to cover all the fruit.
Step 5: Bake Again
Return the assembled baking pan to the oven and bake for an additional 15-20 minutes at 350°F (175°C). The topping should turn a lovely golden brown, and the blackberry filling will bubble slightly at the edges, making it appealing and fully cooked.
Step 6: Cool & Slice
Remove the baking pan from the oven and allow the bars to cool completely on a wire rack. This cooling step is essential for the layers to set properly—aim for at least 1 hour. Once cool, slice into squares and enjoy your delightful Blackberry Pistachio Dream Bars!
