Combine the frozen corn, cream, salt, pepper, sugar and butter in a skillet over medium heat. Bring to a simmer, stirring constantly.
Whisk the flour and milk together until free from lumps, then add to the skillet with the corn mixture. Cook, stirring until it is thickened and the corn is cooked through (about 4 minutes.)
Remove from heat and stir in the Parmesan cheese until melted. It's ready to serve!
