In a large skillet, cook the ground beef or chorizo over medium heat until browned. Drain excess fat.
In a slow cooker, add Velveeta cheese, cream cheese, and shredded cheddar.
Pour in the Rotel tomatoes, milk, and beer (if using).
Add garlic powder, onion powder, smoked paprika, and cayenne pepper. Stir well.
Cover and cook on low for 1-2 hours, stirring occasionally, until the cheese is fully melted.
Stir in chopped cilantro, diced jalapeño, and crumbled bacon just before serving.
Serve warm with tortilla chips.
