Preheat oven to broil. If your oven requires a broil temperature, I go with 550°F.
Add the sour cream and cream cheese to a saucepan and heat over medium heat.
Stir until cream cheese is melted and combined.
Add in the green chiles, corn, cumin, garlic powder, salt, and black pepper. Stir until combined.
Add in half the pepper jack cheese and slowly stir until it's melted and combined.
Pour into a shallow baking dish.
Sprinkle the other half of the pepper jack cheese over the top.
Broil in the oven for 3-4 minutes (watching closely), just until the cheese begins to brown.
Remove from oven and allow to cool for a couple of minutes before serving with your favorite crackers, veggies, or chips!
Notes
I prefer light sour cream and reduced fat cream cheese in this, but you can use full fat versions of both if you prefer. I would not use fat free of either version as it would change the texture.
If you don't have fresh roasted green chiles, you can use canned green chiles.
If you want to make this dip ahead of time, I recommend making it through until topping the cheese and broiling shortly before serving.
