Preheat the oven to 350℉ and spray an 8-inch casserole dish with cooking spray.
Put the cream cheese, jalapeño, garlic powder, chipotle powder, salt, and pepper in a large bowl. Mix together until well combined.
Add the corn. Mix until everything is combined. Add 2 cups of the shredded cheese and stir until combined.
Transfer the mixture to the pan and top with the remaining cheese. Bake for 20 to 30 minutes, or until the cheese is melted and the dip is hot all the way through.
Top with the chopped tomatoes, sliced green onions, and cilantro. Serve with chips.
