Instructions
Preheat your oven to 375°F (190°C). Grease a 9x9-inch baking dish (or soufflé dish) generously with butter.
In a large bowl, stir together the Jiffy Corn Muffin Mix, sour cream, whole kernel corn (drained), creamed corn, cooled melted butter, sugar (if using), and whisked eggs. Fold in the finely chopped jalapeños (reserving some slices for topping) and 1 cup of shredded cheese blend (reserving ½ cup for topping).
Pour the mixture into the prepared baking dish and smooth the top. Sprinkle the reserved cheese blend evenly over the top, then add slices of jalapeno. Optionally, distribute pats of butter on top for a richer, golden-brown crust.
Bake for 45-55 minutes, or until the soufflé is set in the center and the top is golden brown. For an even darker crust, broil the top on high for 1-2 minutes at the end of baking, watching carefully to avoid burning.
Let the soufflé rest for 15 to 30 minutes before serving. The top will be crispy, buttery, and full of cheesy-jalapeño flavor, while the inside remains light and fluffy.
