Preheat your oven to 375°F and grease a 9-inch baking dish or pie plate.
In a large mixing bowl, combine the softened cream cheese, sour cream, cheddar cheese, mozzarella cheese, half of the crumbled bacon, diced jalapeños, garlic, and salt. Mix until well combined and creamy.
Spread the mixture evenly into the prepared baking dish. In a small bowl, combine panko breadcrumbs with melted butter and the remaining bacon crumbles, then sprinkle over the top of the dip.
Bake for 20-25 minutes until the dip is hot and bubbly and the top is golden brown.
Let cool for 5 minutes before serving with tortilla chips, crackers, or pretzel crisps.
