Step‑by‑Step Instructions for Blackberry Pie Bars

Step 1: Prepare the Crust
In a large bowl, whisk together 2 cups of all-purpose flour, ½ teaspoon of baking soda, ½ teaspoon of salt, and 1 teaspoon of ground cinnamon until combined. In another bowl, mix ½ cup of melted unsalted butter with ½ cup of granulated sugar, ¼ cup of light brown sugar, 1 teaspoon of vanilla extract, and the zest of 1 lemon. Fold the wet ingredients into the dry mixture until just combined, forming a crumbly dough.

Step 2: Bake the Crust
Preheat your oven to 350°F (175°C). Set aside ¾ cup of the prepared dough for the topping. Press the remaining dough evenly into a parchment-lined 9×9-inch baking pan, ensuring an even layer. Bake the crust for 14-16 minutes until it turns golden brown. Once done, remove it from the oven and let it cool for about 15 minutes while you make the filling.

Step 3: Make the Filling
In a medium saucepan over medium heat, combine 3 cups of blackberries (fresh or frozen), ½ cup of granulated sugar, a pinch of salt, 2 tablespoons of cornstarch, and the zest and juice of 1 lemon. Bring the mixture to a boil while gently pressing the berries to release their juices. Once boiling, reduce the heat and let it simmer for about 1-2 minutes until the filling thickens. Remove from heat and allow to cool for 10 minutes.

Step 4: Assemble & Bake
Spread the cooled blackberry filling evenly over the baked crust in the pan. Sprinkle the reserved crumb dough on top, covering the filling. Return the pan to the oven and bake for an additional 40 minutes until the topping is golden and the filling is bubbly. The delightful aroma of blackberry pie bars will fill your kitchen as they bake!

Step 5: Cool and Serve
Once the bars are baked, remove them from the oven and let them cool completely in the pan. For clean slicing, chill them in the freezer for about 15 minutes before cutting into bars. Serve your delightful blackberry pie bars with a light dusting of powdered sugar or a dollop of whipped cream, and watch them disappear!
