Preheat the oven to 350°F (175°C).

In a large bowl, combine the strawberries with orange juice, granulated sugar, and ¼ cup flour. Toss to coat and spread the mixture in an even layer in a baking dish.

In another bowl, mix together the oats, ⅔ cup flour, light brown sugar, ⅓ cup granulated sugar, salt, and ground cinnamon.

Drizzle the melted butter over the oat mixture and stir until combined.

Sprinkle the oat mixture evenly over the strawberries.

Bake for 40 minutes or until the topping is golden brown and the strawberries are bubbling.

Serve warm, topped with vanilla ice cream if desired.
