Ingredients
butter, for greasing
4 cups fresh or frozen blackberries
1/4 cup granulated sugar
2 tsp cornstarch
1 tbsp water
1/2 cup cold butter, cut into small cubes
1/2 cup all-purpose flour
1/2 cup brown sugar, firmly packed
1 tsp ground cinnamon
1 cup quick-cooking oats
Directions
Preheat your oven to 375°F. Lightly grease a 10-inch cast iron skillet or baking dish with butter and set aside.
In a medium bowl, combine the blackberries, granulated sugar, cornstarch, and water. Toss gently until the berries are evenly coated and the cornstarch is fully incorporated.
Pour the blackberry mixture into the prepared skillet, spreading it into an even layer.
In a separate medium bowl, combine the flour, brown sugar, cinnamon, and oats. Mix until blended.
Add the cold butter cubes to the oat mixture. Using a fork, pastry cutter, or your fingertips, work the butter into the dry ingredients until the mixture resembles coarse breadcrumbs with pea-sized pieces of butter throughout.
Sprinkle the crumble topping evenly over the blackberry filling, covering it completely.
Bake for 25 to 30 minutes, until the filling is bubbling around the edges and the topping is golden brown. Remove from the oven and let cool for a few minutes before serving.
Comments
Blackberries are abundant and affordable at Charlotte retailers like Harris Teeter and Food Lion during summer months, and all other ingredients are pantry staples found everywhere for roughly $8–10 total, or about $2–2.50 per serving. The 35-minute estimate is honest for assembly and baking, though you'll need 10 minutes of prep work (washing berries, measuring, mixing the crumble topping). This is a straightforward, low-fuss dessert that reheats adequately the next day, though it's best served warm same-night; it suits a family dinner well because a single pan feeds four without demands for attention during the bake.
