Cowboy Cornbread

Heat a large skillet over medium-high heat. Cook and stir beef in the hot skillet until browned and crumbly, 5 to 7 minutes. Drain and discard grease. Add onion; cook until soft, 5 to 10 minutes.

Preheat the oven to 400 degrees F (200 degrees C).

Combine cornbread mix, milk, and eggs in a large bowl. Stir in creamed corn.

Spread beef-onion mixture in the bottom of a baking dish. Spread Cheddar cheese on top. Pour cornbread batter over cheese.

Bake in the preheated oven until golden brown and a toothpick inserted into the center comes out clean, 17 to 22 minutes. Spread butter over the top. Let cool for 5 minutes before cutting.
