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! Add a scoop of vanilla ice cream for the perfect summer treat!
Preheat the oven to 350 degrees Fahrenheit. Spray a 3-quart baking dish with pan spray.
In a medium bowl, toss the berries together with the sugar, flour, cinnamon, salt, and lemon juice. Pour into the prepared baking dish.
In a separate bowl, prepare the crumble topping by whisking together the flour, sugar, cinnamon, and salt. Cut in the 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, until the top is lightly toasted and the filling is bubbling. Let it cool for 5-10 minutes to allow the liquid to cool slightly and thicken a bit before serving. Serve with vanilla ice cream, whipped cream, or creme anglaise if desired.
