Spray your slow cooker with non-stick cooking spray.
Add black beans, cream cheese, sour cream, 1 cup of the Monterey Jack cheese, salsa, chipotle peppers, adobo sauce, onion, garlic, cumin, and smoked paprika to the slow cooker.
Stir everything together until well combined (it's okay if the cream cheese isn't fully mixed yet).
Cover and cook on low for 3 hours, stirring every hour to ensure even melting and prevent sticking.
About 30 minutes before serving, use a potato masher or fork to partially mash the beans for a chunky-smooth texture. Stir in remaining 1/2 cup cheese.
Taste and adjust salt and heat level if needed. Top with fresh cilantro, jalapeños, and diced tomatoes. Serve warm with tortilla chips, pita chips, or crispy vegetables.
