Preheat oven to 400°F. Line a baking sheet with foil and spray with cooking spray.
Place cleaned corn ears on baking sheet, sprinkle liberally with salt and pepper. Top each ear with a pat of butter.
Bake Corn in the oven for approximately 35-40 minutes until starts to brown. Turn corn occasionally during baking. Remove from oven.
In a small pan, melt 1/2 stick unsalted butter. When butter is melted, stir in parmesan cheese and chives. When mixed completely, remove from heat and drizzle immediately over Corn ears. Serve while hot!
