Preparation Steps

• Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
• In a bowl, whisk together flour, baking soda, baking powder, and salt. Set aside.
• In another bowl, cream together the sugar and butter until light and fluffy. Mix in the mashed bananas and vanilla extract.
• Gradually add the dry ingredients into the banana mixture, mixing until just combined. Stir in the walnuts if using.
• Spoon the dough onto the prepared baking sheet, leaving space between each cookie. Bake for 10-12 minutes or until golden brown.
• Allow to cool on the baking sheet for a few minutes before transferring to a wire rack.
