01 - Preheat your oven to 375°F. Lightly grease an 8x8 inch square baking dish with butter or cooking spray.
02 - In a medium mixing bowl, combine the softened cream cheese and sour cream. Beat with a hand mixer or stir vigorously until smooth and creamy.
03 - Fold in the shredded cheddar, mozzarella, chopped jalapeños, garlic powder, onion powder, smoked paprika, salt, and pepper. Mix until all ingredients are evenly distributed throughout the creamy base.
04 - Spread the cheese mixture into the prepared baking dish, using a spatula to create an even layer.
05 - In a small bowl, combine the panko breadcrumbs, melted butter, and grated Parmesan cheese. Mix with a fork until the breadcrumbs are evenly coated with butter.
06 - Sprinkle the breadcrumb mixture evenly over the surface of the dip.
07 - Bake for 20 to 25 minutes, or until the topping is golden brown and the dip is bubbling around the edges.
08 - Remove from the oven. If desired, garnish with additional chopped jalapeño and fresh parsley. Serve warm alongside tortilla chips, crackers, or toasted baguette slices.
