Preheat the Oven:
Preheat your oven to 350°F (175°C). Grease and lightly flour a loaf pan or line it with parchment paper.
Prepare the Wet Ingredients:
In a large mixing bowl, whisk together the mashed bananas, melted butter, sugar, eggs, and vanilla extract until smooth.
Mix the Dry Ingredients:
In a separate bowl, combine the flour, baking soda, salt, and cinnamon.
Combine Wet and Dry Ingredients:
Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Avoid overmixing.
Add the Nuts:
Gently fold in the chopped nuts.
Bake:
Pour the batter into the prepared loaf pan. Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean.
Cool:
Let the banana nut bread cool in the pan for 10 minutes, then transfer it to a cooling rack to cool completely.
