Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.

In a large bowl, mix together the drained whole kernel corn, creamed corn, sour cream, melted butter, eggs, and corn muffin mix until just combined.

Pour the mixture into the prepared baking dish and spread it evenly.

Bake for 45–50 minutes or until the top is golden and the center is set.

Let cool for 5–10 minutes before serving to allow it to firm up.
