With the mixer on medium speed, add eggs one at a time, beating well after each. Scrape down bowl sides as needed. Beat in Greek yogurt, vanilla extract, and mashed bananas until combined.

Add the dry mixture to the wet ingredients and beat on low speed just until combined. Avoid over mixing to maintain a tender crumb.

Gently fold in chopped nuts and/or chocolate chips if using, ensuring even distribution without overworking the batter.

Pour batter into prepared pan and bake for 60 to 65 minutes. Halfway through baking, loosely cover the loaf with aluminum foil to prevent excessive browning. The bread is done when a toothpick inserted in the center comes out clean or with a few moist crumbs.

Wrap the loaf tightly and store at room temperature for up to 3 days or refrigerate for up to 1 week.
