Preheat the oven to 350°F. Place the butter on a large cookie sheet. Transfer the pan to the warm oven and allow the butter to melt while the corn cooks.
Cook the corn using your preferred method. We love to grill ours for extra smoky flavor.
Once the corn is cooked, place each ear on the pan and roll it through the melted butter until evenly coated on all sides.
Sprinkle the garlic powder evenly over each ear of corn. Brush or spoon the garlic Parmesan sauce over the corn until completely coated. Bake for 10 minutes.
Carefully remove the pan from the oven and generously sprinkle the Parmesan cheese over each ear of corn.
Switch the oven to broil and return the corn to the oven for 1 to 2 minutes, watching carefully to prevent burning, until the cheese is melted, bubbly, and lightly golden. Garnish with fresh parsley and serve immediately. Enjoy!
