Cook ground beef and onion in a 6-quart pot over medium heat, breaking up beef with a wooden spoon, until beef is no longer pink, about 8 minutes. Drain grease.
Season with chili powder, garlic, cumin, salt, cayenne pepper, and cinnamon. Cook and stir until fragrant, 1 minute.
Mix in undrained tomatoes, beans, beer, Worcestershire, maple syrup, and tomato paste. Bring to a boil over high heat. Reduce heat to medium-low and simmer, uncovered, until thickened, 20 to 25 minutes.
Garnish with sour cream and green onions, if desired. Recipe developed by Juliana Hale
