Add the ground beef, breaking it apart with a wooden spoon. Cook until browned and no longer pink, about 7–8 minutes. Drain excess fat if necessary.
Stir in the diced bell peppers and fire-roasted green chiles. Sauté for 5–7 minutes, until the peppers soften slightly.
Add all spices, cocoa powder, and Worcestershire sauce to the meat and vegetable mixture. Cook for 2-3 minutes, stirring frequently to bloom the spices in the remaining fat.
Pour in 1–2 cans of beer and scrape up the browned bits from the bottom of the pot. Let it simmer for 2–3 minutes to burn off some of the alcohol.
Stir in the fire-roasted diced tomatoes, tomato paste, beans, and Better Than Bouillon. Mix well to combine.
Bring the chili to a boil, then reduce the heat to low. Simmer uncovered for 30–40 minutes or longer (up to 2 hours), stirring occasionally. Add water as needed if the chili becomes too thick.
Add water as needed during cooking to maintain desired consistency. Up to 2 cups may be needed for longer cooking times.
Taste the chili and adjust the seasonings as needed.
Ladle the chili into bowls and set out garnishes for people to customize their bowls.
