In a large pot, combine ground beef with half the chili powder and brown it together with onion, jalapeño, and garlic. Drain any excess fat.
Mix in the bell pepper, crushed tomatoes, diced tomatoes, and tomato paste. Stir well to combine.
Pour in the beef broth and beer. Add the remaining chili powder, cumin, and brown sugar if using. Season with salt and pepper. Bring to a boil.
Reduce the heat and let it simmer uncovered for about 45-60 minutes, stirring occasionally, until the chili thickens to your liking.
Serve with your favorite toppings like cheddar cheese, green onions, or cilantro. Enjoy!
