Preheat your oven to 400 degrees Fahrenheit.

Tear off four sheets of aluminum foil, large enough to wrap each ear of corn.

Brush each ear evenly with 1 tablespoon of melted butter.

Sprinkle the black pepper and salt evenly over all the ears.

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

Bake for 25 to 30 minutes, turning halfway through, until the kernels are tender.

Carefully unwrap the foil and serve immediately.
