Heat oven to 350 degrees. Grease a 9×13 baking dish with vegetable oil or spray with non-stick cooking spray.
In a large bowl, whisk melted butter and sugar until well blended.
1 cup salted butter, 1 cup sugar
Add the corn, eggs, and green chiles. Stir the cheese into the mixture.
14.75 ounces cream style corn, 4 eggs, 4 ounces chopped green chilis, 1 cup fiesta or Mexican blend shredded cheese
In another large mixing bowl, whisk together flour, corn flour, baking powder, and salt.
1 cup all purpose flour, 1 cup yellow corn flour, 4 teaspoons baking powder, 1/4 teaspoon salt
Add the wet ingredients to the dry ingredients and stir until just blended.
Pour batter into the prepared baking dish and bake for one hour. When done, it will be golden brown, and a toothpick inserted into the center of the cornbread should come out clean.
Allow to cool for 10 minutes prior to slicing into squares and serving.
