Preheat the oven to 400F with the rack on the middle shelf. Coat your baking dish with nonstick spray. Set aside.
In a large bowl, whisk together the flour, cornmeal, baking powder, baking soda, ground red pepper, and salt.
In a medium bowl, whisk together the buttermilk, brown sugar, and eggs.
Fold the egg mixture gently into the flour mixture.
Add the butter, jalapeno, corn kernels, and 1 cup of the Mozzarella. Mix to just combine.
Pour the batter into the prepared dish and level the top. Sprinkle the remaining 1/2 cup of cheese on top.
Bake until cooked through and a toothpick inserted in the middle comes out clean (or with just crumbs), approximately 35-40 minutes.
Remove from the oven and let the bread cool in the pan for approximately 10 minutes. Then remove from the pan and finish cooking on a wire rack.
For a spicier bread, leave the ribs and seeds in the peppers and/or use more peppers.You could also make this in any shape or size baking dish, including as muffins, however your baking time will vary. You will know it is done when a toothpick inserted in the center comes out clean or with crumbs.If you do not have buttermilk on hand, simply add 1 Tablespoon of fresh lemon juice to 1 cup of milk and let it sit for 5 minutes.
