Brown ground beef until cooked through and meat is in small pieces. Remove from heat and drain in a colander. Set aside.
Heat up olive oil and cook onions for about 3 minutes, add garlic and cook for one minute more. Add the ground beef back to the pot and turn down the heat to medium-low.
Stir in tomatoes, beef broth, and chocolate. Add the salt and pepper, bay leaf, chili powder, cumin, coriander, cloves, cinnamon, cayenne, Worcestershire and cider vinegar, stir to combine well.
Cover and simmer for an hour or so, stirring occasionally. See recipe notes for serving ideas.
