Chocolate and bananas are a match made in heaven, so I love loading up my banana bread with chunks of chocolate. I also sometimes add cocoa powder to the batter to make a double chocolate banana bread.  I don't like nuts in my banana bread, but some people like to add chopped walnuts or pecans. This recipe can easily be converted to Banana Nut Bread by adding your favorite nut in place of, or in addition to the chocolate.   For the final variation, you can add some more fruit. Some ideas are sliced bananas, raisins, blueberries, or strawberries.
