Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
In a large bowl, stir together the whole kernel corn, cream-style corn, cream cheese, melted butter, sour cream, and egg until smooth.
Stir in the Jiffy cornbread mix, cheddar cheese, crumbled bacon, and jalapeños until just combined.
Pour the mixture into the prepared dish. Sprinkle extra shredded cheddar cheese on top.
Bake for 40-45 minutes, or until golden brown and set in the center.
Let cool for 5 minutes. Garnish with green onions if desired. Serve and enjoy!
