This fruit crisp is made up of bright, fresh berries, then it's adorned with the most delicious crispy, sweet, buttery, oat filled topping and finished with a generous scoop of rich vanilla ice cream.
Preheat oven to 375 degrees. Butter a 9 by 9-inch or 11 by 7-inch baking dish.
For the crumble: In a mixing bowl whisk together flour, oats, brown sugar, granulated sugar, cinnamon and salt.
Add butter and cut into mixture using a pastry cutter or fork (or rub with fingertips), until mixture resembles coarse crumbs. Transfer to refrigerator.
For the filling: Rinse berries and let drain (but don't dry). Transfer to baking dish.
In a small bowl whisk together sugar and cornstarch. Pour cornstarch mixture evenly over berries then toss to evenly coat.
Remove crumble from refrigerator and sprinkle evenly over berries.
Bake in preheated oven until filling is bubbling and topping is golden brown and crisp, about 30 - 35 minutes. Serve warm with vanilla ice cream.
