Nothing tastes more like late summer than a Blackberry Crumble. Even if you've never baked from scratch before, you will find this recipe so easy to put together.
In a large bowl, gently combine blackberries, sugar and all-purpose flour. Transfer to an 8 x 8 baking dish.
6 cups fresh blackberries, 1/3 cup granulated sugar, 1/3 cup all-purpose flour
For the crumble topping, combine all ingredients in a medium bowl and work together with your hands until the ingredients resemble a crumble.
2/3 cup old-fashioned oats, 1/2 cup dark brown sugar, 1/4 cup all-purpose flour, 3 tbsp butter, softened, 1 tbsp vegetable oil, 1 tsp ground cinnamon, 1/4 tsp table salt
Sprinkle the crumble topping over the blackberry mixture. Bake crumble until the the topping is golden brown and blackberries are bubbling, about 40 minutes. Let cool for 15 minutes before serving. Serve warm or at room temperature, with ice cream if desired.
