Preheat oven to 350° F. Line loaf pan with parchment paper and/or spray with non-stick spray.
In a large bowl, mash the bananas together with a fork until smooth. Add yogurt, honey, eggs, vanilla extract, and melted butter and stir to combine.
In another bowl, whisk together the oat flour, whole wheat flour, protein powder, cinnamon, baking powder, and baking soda.
Fold the dry ingredients into the banana mixture just until combined. Add chocolate chips and walnuts.
Pour batter into the prepared pan. Top with additional chocolate chips, if desired. Bake for 45-50 minutes until a toothpick comes out clean.
