Instructions
Preheat the oven to 350ºF. Prepare 9 × 13 inch baking dish by spraying it lightly with nonstick cooking spray or greasing with butter (see note).
Measure blueberries into the prepared baking dish, add ¼ cup sugar, and cornstarch, and stir to coat.
8 cups fresh or frozen blueberries, ¼ cup granulated sugar, 2 tablespoons cornstarch
In a medium-sized bowl, blend together melted butter, ¾ cup sugar, and vanilla. Add flour, baking powder, cinnamon, nutmeg, and salt; mix well.
½ cup unsalted butter, melted, ¾ cup granulated sugar, 1 teaspoon pure vanilla extract, 1 cup all-purpose flour, 1 teaspoon baking powder, ½ teaspoon ground cinnamon, ¼ teaspoon ground nutmeg, ⅛ teaspoon salt
Spoon mixture evenly onto the blueberries, or scatter it on with your fingers. If you're using the turbinado sugar, sprinkle it over the topping.
Bake for 55 to 65 minutes (baking time depends on whether you use fresh or frozen blueberries). Filling should be bubbling around the edges and top will be lightly browned.
Serve warm or at room temperature. The filling will thicken as it cools. Top each serving with whipped cream or a scoop of vanilla ice cream, if desired.

Notes
Baking dish: We recommend a glass baking dish for this recipe. A glass or ceramic dish distributes the heat more evenly and is non-reactive. Aluminum pans may discolor and give the crumble an off flavor.
Make a smaller crumble: This recipe makes a large dessert but you can halve the recipe and use 9 x 9 inch square baking dish. Cut the ingredient amounts in half.
With different fruit: This recipe works with other berries and fruit, or a combination of them. If you like, substitute 4 cups of sliced or diced apple or peaches for 4 cups of the blueberries to make a mixed fruit crumble. You can substitute strawberries, raspberries, or blackberries, too.
Flavor variations: If desired, add a teaspoon of grated ginger root, or a teaspoon of lemon juice and 1 teaspoon lemon zest to the filling. Ground cardamom can be substituted for the cinnamon and nutmeg, or in addition to them.
