Line a 9-inch square baking dish with parchment paper, allowing the edges to overhang for easy removal.
Combine the white chocolate chips and sweetened condensed milk in a saucepan.
Heat over low heat, stirring constantly, until the mixture is smooth, glossy, and just about to bubble, about 3-4 minutes.
Remove the saucepan from heat and quickly fold in the vanilla extract and a pinch of sea salt, mixing until evenly incorporated.
Gently fold in the candy corn, mixing just until they are evenly coated and distributed throughout the mixture.
Pour the mixture into the prepared baking dish, spreading it out smoothly with a spatula.
Let the fudge set at room temperature for at least 2 hours, or refrigerate for about 1 hour for faster setting.
Once firm and glossy, lift the fudge out using the parchment overhang and cut into squares.
Enjoy the vibrant, chewy candy corn fudge as a festive treat or share it at your next fall gathering.
