Finely chop the jalapeños, including the seeds if desired for spice.
Mix together the jalapeños, softened cream cheese, corn, 1 cup shredded cheese, sour cream, garlic powder, onion powder, and salt. Spread in a baking dish, then top with the remaining ½ cup shredded cheese.
Bake for 20-25 minutes or until bubbly and golden brown. Let cool for 5 minutes, then serve hot with tortilla chips and enjoy!
