Heat the olive oil over medium heat in a large pot. Add the ground beef and break it up into small chunks. Cook about 3-4 minutes, then add the onion and cook until softened, about 5 minutes. Drain excess grease as necessary. Add the garlic and spices and cook 30 seconds longer, stirring until the mixture is well coated with the spice mixture.

Add the Guinness, crushed tomatoes and maple syrup and stir until combined. Bring to a boil, then reduce the heat and stir in the beans. Simmer for about 20-30 minutes or until the mixture has thickened.

Remove from heat and add salt and pepper, to taste. Serve with your favorite toppings and enjoy!
