Defrost bananas if frozen. This should take about an hour if the bananas are still in the peels, less time if they are sliced.
Preheat oven to 350 degrees F after bananas have defrosted.
Peel and mash all bananas. Put aside.
Combine flour, baking soda and salt in a large bowl.
Cream together brown sugar and butter. Mix in vanilla, eggs and mashed bananas. Blend well.
Add banana mixture to flour mixture. Stir in until moistened. Add in chocolate chips and dried cranberries, and stir.
Grease a loaf pan and pour in banana bread dough. Bake for 60-65 minutes in oven, or until a toothpick comes out clean after being inserted in the middle. Cool for 10 minutes before removing from the loaf pan.
