Sour cream makes your corn bread creamy and delicious.
Preheat oven to 425 degrees. Brush an 8-inch-square baking pan with butter. Set aside.
Combine flour, cornmeal, baking powder, and salt in a medium mixing bowl.
Whisk together milk, sour cream, egg, sugar, and butter in a small bowl. Stir in creamed corn. Fold wet ingredients into dry ingredients until well combined.
Pour batter into prepared pan, and bake until set and golden brown on top, about 30 minutes. Cool slightly on wire rack before cutting into squares.
