01 - Preheat oven to 375°F. Lightly grease an 8x8 inch baking dish with butter or cooking spray.
02 - In a medium bowl, beat cream cheese until smooth. Add sour cream, cheddar, mozzarella, chopped jalapeños, garlic powder, onion powder, smoked paprika, salt, and pepper. Mix until fully incorporated and creamy.
03 - Spread the cheese mixture evenly into the prepared baking dish, smoothing the top with a spatula.
04 - In a small bowl, combine panko breadcrumbs, melted butter, and Parmesan cheese. Mix until breadcrumbs are evenly coated.
05 - Sprinkle breadcrumb mixture evenly over the dip. Bake for 20 to 25 minutes until the top is golden brown and the edges are bubbling.
06 - Remove from oven. Top with reserved chopped jalapeño and fresh parsley if desired. Serve immediately with tortilla chips, crackers, or sliced baguette.
