- 3/4 cup (180g) brown sugar
- 2 eggs, at room temperature
- 1 tsp (4g) vanilla extract
- 1 1/4 cups (295g) mashed ripe bananas (about 2-3 large bananas)
- 1/2 cup (140g) sourdough discard, at room temperature (or substitute with 1/2 cup Greek yogurt)
- 1/2 cup (115g) Greek yogurt, at room temperature
- 2 1/2 cups (315g) all-purpose flour

- 1 tsp (3g) cinnamon
- 1/2 tsp (3g) salt
- 1 cup (200g) chocolate chips or chunks of choice

Directions
- Preheat the oven to 350°F. Grease and line a standard (9×5”) loaf pan with parchment paper. Set aside.
- In a saucepan over medium-high heat, add the butter and allow it to melt and brown slightly (about 5 minutes). Once browned, remove from heat and pour into a large bowl. Let cool slightly.
- In a medium bowl, whisk together the flour, baking soda, baking powder, cinnamon, and salt. Set aside.
- Once the brown butter has cooled, add the brown sugar and whisk to combine, then add the eggs and vanilla, mixing until well combined.
- Mix in the mashed bananas, sourdough discard, and Greek yogurt until everything is well incorporated.
- Fold the dry ingredients into the wet mixture until there are no streaks of flour. Gently fold in the chocolate chips.
- Pour the batter into the prepared loaf pan. Bake for 60-65 minutes or until golden brown and a toothpick inserted in the middle comes out clean or with a few moist crumbs.
- Cool in the pan for 5-10 minutes, then transfer to a serving plate or wire rack. Slice and serve warm with butter and a sprinkle of flaky sea salt if desired.

- Use very ripe bananas for maximum sweetness (the browner, the better).
- If your batter feels too thick, a splash of milk can loosen it up a bit.
- Experiment with mix-ins! Chopped nuts or different chocolate varieties can add fun textures.
- Let it cool! It slices better and tastes even yummier after a little time to settle.
