Ingredients
For the Crumble Topping
- 3/4 cup old fashioned rolled oats
- 3/4 cup all-purpose flour
- 1/2 teaspoon baking powder
- 1/2 teaspoon cinnamon
- 1/4 teaspoon salt
- 1/4 cup light brown sugar
- 6 tablespoons unsalted butter (melted)
For the Fruit Filling
- 4 large apples (peeled, cored, and diced)
- 2 cups blueberries
- 1 tablespoon lemon juice
- 2 tablespoons light brown sugar
- 2 tablespoons granulated sugar
- 1 tablespoon all-purpose flour
- 1/4 teaspoon salt
- 1/2 teaspoon cinnamon
Instructions
- Preheat the oven: Set your oven to 350°F (175°C) to prepare it for baking the crumble.
- Make the crumble topping: In a mixing bowl, whisk together the oats, flour, baking powder, cinnamon, salt, and light brown sugar. Pour in the melted butter and mix thoroughly until the mixture resembles coarse crumbs.
- Prepare the fruit filling: In a large baking dish, combine the diced apples, blueberries, lemon juice, light brown sugar, granulated sugar, flour, salt, and cinnamon. Stir gently to evenly coat the fruit with the sugars and spices.
- Assemble the crumble: Evenly spread the crumble topping over the fruit mixture in the baking dish, ensuring the fruit is fully covered.
- Bake the crumble: Place the baking dish in the preheated oven and bake for 40 to 50 minutes, or until the apples are soft and the fruit filling is bubbling around the edges.
- Cool before serving: Remove the crumble from the oven and let it cool on the counter for about 10 minutes to allow the filling to set slightly before serving.
Notes
- The crumble topping can be made ahead and refrigerated for up to 24 hours.
- Use tart apples like Granny Smith for a balance of sweetness and acidity.
- For extra crunch, sprinkle chopped nuts like walnuts or pecans on top before baking.
- Serve warm with vanilla ice cream or whipped cream for an indulgent dessert.
- Leftovers can be stored in the refrigerator and reheated in the oven before serving.
