In a large pot over medium-high heat, cook the ground beef with the chili powder, breaking it up as it browns.
Add the diced onion, jalapeños, and garlic. Cook until the veggies have softened, then drain any excess fat.
Add the diced green bell peppers, cumin, tomato paste, beef broth, beer, diced tomatoes, kidney beans, pinto beans, brown sugar, and salt. Stir well to combine.
Bring the mixture to a boil. Reduce the heat and simmer uncovered for 45–60 minutes, stirring occasionally.
Serve the chili hot with your favorite toppings. Enjoy!
