Preheat the oven to 400 degrees F and prepare four sheets of aluminum foil.

Place each ear of shucked corn on a separate piece of foil.

Rub 1 tablespoon of softened butter over each ear, then sprinkle evenly with the black pepper.

Wrap each ear tightly in the foil and place them directly on the center oven rack.

Bake for 30 minutes, turning once halfway through, until the kernels are tender.
