Preheat your oven to 350 degrees Fahrenheit. This step is crucial as it ensures that your cornbread will bake evenly and rise properly.
In a large bowl, combine the creamed corn, sour cream, and vegetable oil. Mix them well until you achieve a smooth consistency. The combination of these ingredients will create a rich base.
Add the Jiffy Corn mix, sugar, and eggs to the bowl. Stir everything together until it’s just blended. Be careful not to overmix; a few lumps are okay as they will bake out.
Take a greased 9×11 inch pan and pour the batter into it. Use a spatula to spread it evenly, ensuring you reach the corners of the pan for uniform baking.
Place the pan in the preheated oven and bake for 35 to 40 minutes. You'll know it’s done when the top is golden brown and a toothpick inserted in the center comes out clean.
Once baked, let the cornbread cool for a few minutes before slicing. This cooling period allows the texture to set perfectly, making it easier to cut.
Serve warm with butter or alongside your favorite dish. Enjoy the sweet, comforting flavor!
