Preheat your oven by turning on the broiler. Place the rack in the middle rack position.
Start by draining a can of corn. Once fully drained, transfer to a medium-sized mixing bowl.
To the mixing bowl, add chopped pickled jalapenos, cream cheese, 1 1/4 cup shredded mozzarella, Kewpie mayo, scallions, sugar, garlic powder, cayenne pepper, salt, ground black pepper, and melted unsalted butter. Mix until well combined.
Transfer to a baking dish and smooth out the top. Add 1/4 cup shredded mozzarella cheese, making sure to spread it out in an even layer.
Place the baking dish in the oven, making sure that it's about 6 inches from the broiler. Broil for 15 minutes or until the cheese has turned golden brown. Remove and garnish with scallions. Serve with your favorite chips or vegetables!
