Preheat the oven to 350°F (175°C).
Grease an 8x8-inch or 9-inch round baking dish.
Mix the wet ingredients.
In a medium bowl, whisk together the eggs, sour cream, and melted butter.
Add remaining ingredients.
Stir in both cans of corn, Jiffy mix, shredded cheese, chives, and spices. Mix until just combined, don’t overmix!
Pour into the baking dish.
Smooth the top with a spatula and place in the preheated oven.
Bake uncovered for 45–50 minutes.
The top should be golden, slightly puffed, and a toothpick inserted in the center should come out clean.
Rest, then serve.
