2Cut 5 squares of aluminum foil 1 1/2 times the size of the ears of corn; place each ear of corn in the center of a piece of foil.
3Stir mayonnaise, Parmesan cheese, chili powder, ground black pepper, and fresh parsley together in a bowl until it forms a thick paste; rub about 2 tablespoons of the paste over each ear of corn. Wrap the aluminum foil around the corn and seal. Arrange corn on a baking sheet.
4Bake in preheated oven for 10 minutes, turn, and continue baking another 10 minutes.

Cook's Note:
After corn is wrapped in aluminum foil, you can store them in resealable freezer bags in the refrigerator for up to 2 days or in the freezer for up to 1 month. When ready to use, defrost the corn overnight in the refrigerator; then let come to room temperature for about 30 minutes before baking as directed.
