Shuck corn and remove threads. If you would like to keep the husks on, simply peel back, remove on of the husk pieces and tie. From there gently remove the threads and rinse the ears of corn. Blot dry with a paper towel.
Brush corn with oil and put on the grill. Close the lid and cook for 3-4 minutes. Turn corn, close lid and continue cooking for another 2-3 minutes.
Separate the butter mixture in half. Save one for serving and use the other to baste. Using a heat-safe basting brush, start applying the butter mixture onto the ears of corn. Turn and coat again. Repeat the process once more, and let corn cook until it takes on a slightly charred appearance and the kernels are tender.
Remove corn from the grill and serve with reserved half maple-butter.
