Preheat the oven and prepare the pan

• Preheat the oven to 375 °F.
• Line a loaf pan with parchment paper.

Mix the dry ingredients

• In a bowl, whisk together the flour, baking powder, baking soda, salt and cinnamon until evenly combined.

Combine bananas and browned butter

• In another bowl, whisk the mashed bananas and browned butter until combined.

Add the sugars

• Add the brown sugar and granulated sugar and mix until smooth.

Add the wet ingredients

• Add the egg, Greek yogurt and vanilla and whisk until the batter is smooth.

Fold in the dry ingredients

• Add the dry ingredients to the wet ingredients and gently fold until mostly combined, with a few streaks of flour remaining.

Fold in the chocolate chips

• Add the mini chocolate chips and fold just until incorporated, avoiding overmixing so the loaf stays soft and fluffy.

Fill the loaf pan

• Pour the batter into the prepared loaf pan and smooth the top.
• Scatter extra chocolate chips on top if desired.

Bake the banana bread

• Bake for 5 minutes at 375 °F, then reduce the oven to 350 °F.
• Continue baking for 40–50 minutes, until a toothpick inserted in the center comes out with a few moist crumbs.

Cool the loaf

• Let the loaf cool in the pan for about 15 minutes.
• Transfer to a rack to cool completely.
