2. Lightly spray a 13x9 baking dish with cooking spray and set aside.

For The Fruit Filling

1. Place blueberries, lemon juice and zest in a large bowl and stir to combine.
2. In a small bowl, whisk together the sugar, flour and cinnamon. Sprinkle over berries and toss gently to coat.
3. Transfer the berries to the prepared baking dish.

For The Topping

1. In a medium bowl, whisk together flour, sugar, baking powder and salt. Add the cubed butter, working it into the flour mixture until small pea-sized crumbles form.
2. Gradually add milk, stirring after each addition, until well combined.
3. Spoon the topping onto the blueberries, carefully spreading it slightly. The mixture will be thick but will continue to spread while baking.
4. Bake for 40-45 minutes or until the top is golden brown.
