Instructions

1. Prep:

Preheat oven to 350°F (175°C). Grease a 9×9″ or 2-qt baking dish.

2. Make corn base:

In a large bowl, combine whole kernel corn, cream-style corn, Jiffy mix (or homemade blend), sour cream, melted butter, and egg. Mix until smooth.
Stir in 1 cup cheese and green chiles (if using).

3. Swirl cream cheese:

Dollop cream cheese mixture over corn base.

Gently swirl with a knife—4–5 figure-8 motions only (over-swirling = muddy mix).

4. Top & bake:

Sprinkle remaining ½ cup cheese on top.
Bake 40–45 minutes until golden and center is set (no jiggle).

Rest 10 minutes before serving.
