Ingredients:
- 1⅓ cups all-purpose flour
- ½ teaspoon salt
- ½ teaspoon sugar
- ½ cup unsalted butter, cold and diced
- 4-5 tablespoons ice water
- 3 cups fresh or frozen blackberries
- ½ cup granulated sugar
- 2 tablespoons cornstarch
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
- ¼ teaspoon ground cinnamon
- 1 tablespoon butter, diced
- Vanilla ice cream or whipped cream for serving
Instructions:
- In a mixing bowl, combine flour, salt, and sugar. Add the cold, diced butter to the flour mixture. Use a pastry cutter or your fingers to work it into the flour until it resembles coarse crumbs. Gradually add ice water, one tablespoon at a time, mixing until the dough holds together. Gather the dough into a ball, flatten it into a disk, wrap in plastic, and refrigerate for at least 30 minutes.
- In a medium saucepan over medium heat, combine the blackberries, granulated sugar, cornstarch, lemon juice, vanilla extract, and cinnamon. Stir gently until the mixture is well combined. Cook for 5-7 minutes or until the mixture begins to bubble and thicken. Remove from heat and let it cool slightly.
- Preheat your oven to 375°F (190°C).
- On a lightly floured surface, roll out the chilled pie dough to fit your pie dish. Transfer the dough into the dish and trim any excess hanging over the edges.
- Pour the cooled blackberry filling into the prepared crust. Dot the filling with the diced butter to enhance flavor.
- Bake in the preheated oven for 45-50 minutes, or until the crust is golden and the filling is bubbly. Check the pie after 30 minutes; if the crust edges are browning too quickly, cover them with strips of aluminum foil.
- Allow the pie to cool for at least 15-20 minutes before slicing. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream, if desired.
