Homemade Strawberry Crumble

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease an 11×7-inch baking dish.

Step 2
Stir together flour, oats, walnuts, ginger, and 3/4 cup brown sugar in a bowl. Add butter; using your hands, stir mixture until moistened and coarse crumbs form.

Step 3
Stir together cornstarch, vinegar, and remaining 1/4 cup brown sugar in a large bowl until combined, then stir in the strawberries. Transfer to the prepared baking dish and top with crumble mixture.

Step 4
Bake in the preheated oven until the strawberries are tender, mixture is rapidly bubbling around all edges, and top is golden, 45 to 50 minutes.

Step 5
Remove from oven and let sit at room temperature, about 10 minutes. Serve warm with vanilla ice cream.
