In a mixing bowl, combine corn, mozzarella cheese, mayonnaise, and sugar. Mix well.
Melt butter in an oven-safe skillet or baking dish.
Pour the corn mixture into the skillet and spread evenly. Season with salt and pepper.
Bake for 10-15 minutes, or until the cheese is melted and bubbly.
Serve immediately and enjoy!
Notes
Feel free to add other ingredients such as diced onions, bell peppers, or jalapenos for extra flavor. A sprinkle of parmesan cheese on top also adds a nice touch.
