Classic Banana Bread

Preheat the oven to 350°F (177°C). Grease a 9x5 loaf pan and line it with parchment paper.

In a large bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt.

In a stand mixer or using an electric mixer, beat the butter, granulated sugar, and brown sugar together for 4-5 minutes until light and fluffy.

Add eggs, one at a time, and mix well after each addition. Then stir in the vanilla extract.

Scrape the sides of the bowl, then add the mashed bananas and mix until fully incorporated.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing.

Fold in the chopped walnuts, if using.

Transfer the batter to the prepared loaf pan, spreading it evenly.

Bake at 350°F (177°C) for 55-65 minutes or until a toothpick inserted into the center comes out clean. If needed, tent the loaf with foil to prevent over-browning.

Remove from the oven and let cool in the pan for 20 minutes before transferring to a wire rack to cool completely.
