Preheat the oven to 375°F. Grease a baking dish.

In a bowl, mix flour, sugar, baking powder, and salt. Cut in cold butter until mixture resembles coarse crumbs.

Spread blueberries evenly in the prepared dish. Sprinkle the flour mixture over the blueberries.

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

Let cool slightly before serving. Enjoy!
