In a large bowl, toss the shredded cheese with cornstarch until evenly coated.
In a medium saucepan, pour the evaporated milk and heat over medium heat, stirring occasionally until it just starts to simmer.
Remove the saucepan from the heat and gradually add the cheese mixture to the hot milk, a handful at a time, stirring constantly until all the cheese has melted and the sauce is smooth.
Stir in the Creole Kick seasoning, hot sauce (if using), salt, and ground cayenne pepper.
Taste the sauce and adjust seasoning as needed, adding more cayenne pepper or Creole Kick for extra flavor and heat if desired.
Serve the cheesy sauce over nachos, fries, or steamed vegetables, and enjoy the irresistible Creole-infused goodness!
