Preheat your grill to 400°F.

Mash butter with salt, garlic powder, and pepper until smooth.

Rub each ear of corn with the butter mix. Wrap in foil (2 per packet or individually). Use a double layer if needed.

Grill for 10 minutes, then flip the corn carefully.

Grill another 10–20 minutes until golden and tender.

Serve hot with extra butter and a sprinkle of salt!
