In a medium saucepan, combine 3 cans (15 oz each, drained) corn, ½ cup milk, 1 tablespoon sugar, 1 teaspoon salt, and ½ teaspoon pepper. Stir to combine.
Add 8 oz cream cheese (cut into cubes) and ½ cup unsalted butter (cut into thin slices).
Heat over medium-high heat, stirring frequently, until the cream cheese and butter are fully melted and the mixture is smooth and combined.
