In a large bowl, add both cans of corn, the corn bread mix, the sour cream, melted butter, and 1/2 - 1 cup shredded cheese. Stir to evenly combine.
Pour into a lightly greased 9 x 13 baking dish.
Bake until golden brown and bubbly, about 45 minutes.
Top with remaining cheese, then return to oven until cheese has melted, about 5-10 minutes.
Notes
I like shredded cheddar for this, but try it with parmesan or pepper jack too. And if you want to kick up the spice and deepen the flavor, toss in sautéed jalapeño and garlic.
