Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9×9-inch baking dish.

Mix whole and creamed corn, cornbread mix, sour cream, melted butter, and eggs together in a medium bowl until well combined. Spoon mixture into the prepared dish.

Bake in the preheated oven until the top is golden brown and a toothpick inserted in the center comes out clean, about 45 minutes.
