Ingredients
  

Pie Crust
  • 1 store-bought pie crust or homemade single crust
Blackberry Filling
  • 5-6 cups blackberries fresh or frozen
  • 0.75 cup granulated sugar
  • 0.25 cup cornstarch
  • 1 tbsp fresh lemon juice
  • 1 tsp vanilla extract
  • 0.25 tsp salt
Crumb Topping
  • 1 cup all-purpose flour
  • 0.5 cup brown sugar packed
  • 0.25 cup granulated sugar
  • 0.5 tsp ground cinnamon
  • 0.25 tsp salt
  • 0.5 cup unsalted butter cold and cubed

Equipment

  • 9-inch Deep-Dish Pie Plate
  • Mixing bowls
  • Pastry blender or forks
  • Baking sheet

Method
 

  1. Preheat oven to 400°F (200°C). Fit the pie crust into a 9-inch deep-dish pie plate and chill in the refrigerator.
  2. In a bowl, whisk together flour, brown sugar, granulated sugar, cinnamon, and salt for the crumb topping.
  3. Cut the cold, cubed butter into the dry ingredients using a pastry blender or fingers until it forms pea-sized crumbs. Chill in the fridge.
  4. In a large bowl, gently toss the blackberries with granulated sugar, cornstarch, lemon juice, vanilla, and salt until evenly coated.
  5. Pour the berry filling into the chilled pie crust, scraping out all the juices.
  6. Sprinkle the chilled crumb topping evenly over the fruit filling.
  7. Place pie on a foil-lined baking sheet and bake at 400°F (200°C) for 20 minutes.
  8. Reduce temperature to 375°F (190°C) and bake another 35-45 minutes until topping is golden brown and filling is bubbling thick.
  9. Cool completely on a wire rack for at least 3-4 hours before slicing.

Notes

If the crumb topping begins to brown too quickly in the oven, tent the pie loosely with aluminum foil for the remainder of the baking time. Best served with vanilla ice cream.
