Easy Blueberry Cobbler

Preheat oven to 350 degrees F (175 degrees C). Place butter in an 8-inch square baking dish.

Melt butter in the preheating oven about 5 minutes. Remove from oven.

Mix flour sugar and milk in a bowl until combined; pour batter over melted butter. Scatter blueberries over batter.

Bake in preheated oven until a toothpick inserted into the center comes out clean about 1 hour.
