Incredible Blackberry Crumble is a warm baked fruit dessert that is topped with a sweet, buttery, crumbly crust. It's one of the easiest, most delicious dessert recipes!
Preheat the oven to 350 degrees Fahrenheit. Spray a 3-quart baking dish with pan spray.
In a medium bowl, toss 24 ounces fresh or frozen blackberries together with 2 tablespoons granulated sugar, 1 tablespoon flour, ¼ teaspoon ground cinnamon, 1 dash salt, and 1 teaspoon fresh lemon juice. Pour into the prepared baking dish.
In a separate bowl, prepare the crumble topping by whisking together 1 cup all-purpose flour, 1 cup granulated sugar, ½ teaspoon ground cinnamon, and 3 dashes salt. Cut in ½ cup unsalted butter with a pastry cutter until the mixture resembles coarse breadcrumbs.
Sprinkle the crumble topping evenly over the blackberry mixture and bake for 25-30 minutes, or until the top is lightly toasted and the filling is bubbling. Let it cool for 5-10 minutes to let the liquid thicken before serving. Serve with vanilla ice cream, whipped cream, or creme anglaise, if desired.
