The concept of fruit crumbles dates back to British cuisine in the early 20th century, where it was originally called a “crisp.” Over the years, it has evolved into various regional versions with different fruits and toppings. The addition of oats to the crumble topping has become a popular twist, adding a hearty texture and nutty flavor.

For the Blueberry Filling:

  • 4 cups fresh or frozen blueberries
  • 1/2 cup granulated sugar
  • 1 tablespoon cornstarch
  • 1 tablespoon freshly squeezed lemon juice
  • 1 teaspoon vanilla extract

For the Oat Crumble Topping:

  • 1 cup old-fashioned rolled oats
  • 1/2 cup all-purpose flour
  • 1/2 cup brown sugar, packed
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, cold and cubed


Blueberry Filling:

  1. Preheat your oven to 350°F (175°C) and grease a 9×9-inch (23×23 cm) baking dish.
  2. In a large mixing bowl, combine the blueberries, granulated sugar, cornstarch, lemon juice, and vanilla extract. Gently toss to coat the blueberries evenly.

Oat Crumble Topping:

Assembly and Baking:

  2. Place the baking dish in the preheated oven and bake for about 40 minutes or until the topping is golden brown, and the blueberry filling is bubbling around the edges.
