Description

This crumbly blackberry cobbler recipe has a crumbly, cookie-like crust made with cornflakes and rolled oats, and a thick and delicious berry filling.

Ingredients

1/4 cup cold water
3 tablespoons cornstarch
4 cups fresh blackberries
1/2 cup white sugar
1/2 cup brown sugar
1 teaspoon vanilla extract
1 cup cornflakes cereal, coarsely crushed
1 cup all-purpose flour
1/2 cup old-fashioned rolled oats
1/3 cup brown sugar
1/2 teaspoon pumpkin pie spice
1/2 teaspoon salt
1/4 cup butter
2 tablespoons cold water, or as needed
1/4 cup melted butter

Directions

1 Preheat the oven to 375 degrees F (190 degrees C).
2 Whisk ¼ cup water and cornstarch together in a medium saucepan until smooth; stir in blackberries, white sugar, and ½ cup brown sugar. Bring to a boil over medium heat; stir until filling thickens, about 2 minutes. Off heat, stir in vanilla extract. Pour filling into a 9x13-inch baking dish; set aside.
3 Combine cornflakes, flour, oats, ⅓ cup brown sugar, pumpkin pie spice, and salt in a large bowl. Cut in ¼ cup butter with a pastry cutter until mixture resembles coarse crumbs; stir in 2 tablespoons water, 1 tablespoon at a time, until crust begins to hold together. Sprinkle crust over filling; drizzle with ¼ cup melted butter.
4 Bake in the preheated oven until crust begins to brown, about 10 minutes. Turn on the broiler and broil until crust is golden brown, about 2 minutes more.
