Preheat the oven to 350 degrees. In a large bowl combine flour, baking soda, salt and cinnamon. In a food processor or blender combine dates, bananas, eggs, apple cider vinegar and coconut oil. Add mixture from food processor to dry mixture, and combine thoroughly. Once combined, fold in carrots and nuts. Spoon mixture into paper lined muffin tins and bake at 350 for 25 minutes.
