01 - Preheat oven to 375°F. Lightly grease an 8x8 inch square baking dish with butter or cooking spray.
02 - In a medium mixing bowl, beat the softened cream cheese and sour cream until smooth. Fold in the shredded cheddar, mozzarella, chopped jalapeños, garlic powder, onion powder, smoked paprika, salt, and pepper. Mix until thoroughly combined.
03 - Spread the cheese mixture evenly into the prepared baking dish, using a spatula to create a smooth surface.
04 - In a small bowl, combine panko breadcrumbs, melted butter, and grated Parmesan cheese. Stir until the breadcrumbs are evenly coated with butter.
05 - Sprinkle the breadcrumb mixture evenly over the dip. Bake for 20 to 25 minutes until the topping is golden brown and the dip is bubbly around the edges.
06 - Remove from oven and let cool for 5 minutes. Garnish with reserved chopped jalapeño and fresh parsley if desired. Serve warm with tortilla chips, crackers, or sliced baguette.
