1 cup cornmeal
1 cup flour
½ cup sugar
1 tablespoon baking powder
1 teaspoon salt
2 eggs
2/3 cup milk
½ cup oil
2 cups blueberries
Preheat oven to 400°. Grease a 9-inch square baking dish. Mix cornmeal, flour, sugar, baking powder and salt in a bowl. Beat eggs, milk and oil together in a separate large bowl. Add cornmeal mixture to the egg mixture; mix until just combined. Fold blueberries into the batter; pour into the prepared baking dish. Bake in the preheated oven until a toothpick inserted into the center comes out clean, 25 to 30 minutes.
