Preheat oven to 350℉ / 180℃. Line a 9x5-inch loaf pan with parchment paper that hangs over the longer sides of the pan like wings.
In a medium bowl hand whisk together flour, baking soda, salt, cinnamon and nutmeg. Set aside.
282 grams all purpose flour, 1 teaspoon baking soda, ½ teaspoon fine sea salt, ½ teaspoon ground ginnamon, ¼ teaspoon ground nutmeg
Using a separate large bowl combine melted butter with the granulated sugar and dark brown sugar. Hand whisk together until well combined.
113 grams unsalted butter, 165 grams dark brown sugar, 50 grams granulated sugar
Add the following ingredients one at a time and gently mix until incorporated. Hand whisk in mashed bananas, then eggs, greek yogurt, and vanilla extract.
464 grams mashed overripe bananas, 100 grams whole eggs, 120 grams full fat Greek yogurt, 2 teaspoons pure vanilla extract or vanilla bean paste
Next, sprinkle flour mixture a 1/2 cup at a time into the wet mixture, whisking enough to completely mix in flour without over working batter.
Then fold semi-sweet morsels into the batter with a rubber spatula.
128 grams semi-sweet chocolate chips
Pour batter into prepared loaf pan. Place pan on the middle oven rack.
Bake for 65-70 minutes until toothpick inserted comes out mostly clean with a few moist crumbs.
Place pan on cooling rack for 10 minutes before lifting loaf from pan by pulling upward on over hanging parchment paper.
