Preheat oven to 400°F. Spray a 9x9 inch baking dish with vegetable spray. Set aside.
Combine the cornmeal, flour, brown sugar, salt, baking soda, baking powder and jalapeno pepper in a large mixing bowl.
In a separate bowl add the beaten eggs, buttermilk and cheese. Mix well.
Make a well in the middle of the dry ingredients and pour the egg mixture in the well. Gently blend until the eggs are incorporated, taking care not to over-mix. Fold in the fresh corn, melted butter and rosemary. Pour the batter into the prepared pan and bake until a toothpick inserted into the center comes out clean. About 30 - 35 minutes.
