If using frozen corn, cook briefly and let it cool. Drain canned corn well before using.
In a bowl, mix softened cream cheese, sour cream, cheddar cheese, garlic, smoked paprika, salt, and black pepper until smooth.
Fold in the corn, chopped jalapeños, and green onions until evenly combined.
Transfer to a skillet or baking dish and warm until the cheese is melted and the dip is creamy.
Garnish with cilantro, extra jalapeños, or cotija cheese. Serve warm with tortilla chips, crackers, or fresh vegetables.
