Preheat the oven to 200°C and grease the muffin molds. In a large bowl mix all dry ingredients and set aside. In another bowl, mix the wet ones and add the dry ones little by little. Go stirring as you pour the dry mixture. You can add more coffee or more cinnamon depending on the intensity of flavor you want. Divide the mixture into 12 muffin molds, fill up to 3/4 of the capacity. You can add chocolate chips on top if you wish. Bake for 20-25 minutes or until they are cooked inside.
