Note: This is a bread-machine recipe. My bread machine makes small loaves
that require about 2 cups of flour. If your bread machine typically requires
more flour, then scale the amounts of the ingredients appropriately.
Also note: This is not the thick sweet banana bread you're probably accustomed to eating at holiday time. This is more of a banana-flavored bread, though it is reasonably sweet and a little thicker than ordinary bread.
Put ingredients in bread machine, starting with wet ingredients, then flour and dry ingredients, then the yeast on top. Set it on "Sweet" setting and "Light" crust, if your bread machine has those options, otherwise the "White" setting basically does the job. If the dough looks too moist after the first kneading, I usually find that a little extra flour never hurts. Add the chocolate chips after the first sequence of mixing -- my bread machine stops and beeps when it's ready for add-ins. (Adding them in earlier crushes them and melts them, in which case you get banana-chocolate bread, which isn't bad either.) Start up that machine and let her go...hours later you should get a dense, moist loaf of some of the most delicious bread I've ever tasted. These loaves usually rise less and come out a bit smaller than normal loaves of bread.
