Preheat oven to 400°F and grease a 8-9-inch cast iron skillet or square baking dish.
Stir together sour cream and cream cheese until well mixed.
If your pulled pork is in big chunks or long fibers, roughly chop it until it is smaller bite sized pieces. Stir pork, jalapeno, corn and garlic powder into cream cheese mixture.
Spread the dip in the prepared pan, the sprinkle with cheddar cheese. Bake for 15-18 minutes or until the cheese all looks hot and melted.
If desired, garnish with a drizzle of BBQ sauce, and a sprinkle of chopped cilantro and/or green onions. Serve with sturdy tortilla chips or vegetables.
Notes
You can double the recipe and bake it in a 9x13-inch pan or a 12-inch cast iron skillet.
