Preheat oven to 350 degrees and line or spray 2 small bread loaf pans.
In a large bowl, smash the bananas with a fork.
Add the cake mix and eggs; mix well.
Evenly distribute the cake batter into the prepared loaf pans. Top with chocolate chips, walnuts, or anything else you'd like (optional).
Bake for 25-35 minutes, or until a toothpick comes out clean.
