Cook corn according to the package directions and set aside. (I like to buy the microwavable bags!)

Melt butter in a medium saucepan over medium heat. Whisk in flour. Cook until bubbly, about 1 minute. Gradually whisk in the cream and milk. Cook, stirring constantly, until the sauce thickens. Turn heat to low and add sugar, salt, and pepper. Stir in cooked corn.

Preheat the broiler to low. Pour the corn mixture into a small greased casserole or baking dish that can go under the broiler. Top evenly with Parmesan cheese. Broil until hot and bubbly. (watch closely the entire time!) Serve warm and enjoy!
