Step 1

Preheat the oven to 350°F. Coat a deep-dish pie plate or 8 x 8-inch baking dish with cooking spray.

Step 2

Put the butter in a large microwave-safe bowl and microwave until melted, about 1 minute.

Step 3

Stir in the creamed corn, whole corn kernels, scallions, and sour cream. Add the egg and mix well. Add the cornbread mix and stir just until no dry mix remains—do not overmix.

Step 4

Pour the batter into the baking dish and cook for about 1 hour, until beginning to brown around the edges and a toothpick inserted in the center comes out clean. Cut into squares and serve.
