Preheat the oven to 350 degrees F (180 degrees C). Grease a baking dish with butter or nonstick spray, and set aside.

In a large bowl, combine whole kernel corn, cream style corn, sour cream, Cheddar cheese, honey, and melted butter, stirring until well combined.

In a separate bowl, whisk together cornmeal, baking powder, garlic powder, salt, and pepper. Gradually add the cornmeal mixture to the corn mixture, stirring until combined.

Add the beaten eggs, stirring gently until just incorporated into a batter. Pour the batter into the prepared casserole dish, spreading it out evenly.

Bake the casserole in the preheated oven until the top is golden brown, about 35 to 45 minutes.

Allow the casserole to cool for about 5 minutes. Drizzle honey on top if desired for extra sweetness, garnish with parsley, and serve.
