Preheat your oven to 350°F (175°C).
In a mixing bowl, combine the thawed corn kernels, diced green chilies, softened dairy-free cream cheese, dairy-free sour cream, and dairy-free mayonnaise. Mix until well combined.
Add in the diced red bell pepper, chopped green onions, dairy-free shredded cheese (if using), smoked paprika, and garlic powder. Season with salt and pepper to taste. Stir until all ingredients are evenly incorporated.
Transfer the mixture into a greased baking dish, spreading it out evenly with a spatula.
Bake in the preheated oven for 25-30 minutes, or until the dip is hot and bubbly around the edges.
Remove from the oven and let it cool slightly before serving.
Garnish with chopped fresh cilantro or parsley if desired.
Serve warm with tortilla chips or fresh vegetables.
