Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking and ensure even baking. Mash the ripe bananas in a bowl until smooth and set aside.

In a large mixing bowl, cream the softened butter and brown sugar until light and fluffy. Use a hand or stand mixer for the best results. Add the mashed bananas, egg, and vanilla extract. Mix until fully combined, creating a silky, fragrant batter.

In a separate bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt. This ensures even distribution of leavening agents and spices, giving your cookies the perfect texture and flavor.

Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Avoid overmixing; a few lumps are okay and keep the cookies tender. If you’re adding chocolate chips, walnuts, or shredded coconut, fold them in now for an extra burst of flavor and texture.

Using a cookie scoop or tablespoon, drop dollops of dough onto the prepared baking sheet, spacing them about 2 inches apart. Lightly flatten each scoop with the back of a spoon for even baking.

Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until the edges are golden and the centers look set. Avoid overbaking, as these cookies are best enjoyed with a soft, chewy texture.

Remove the cookies from the oven and let them cool on the baking sheet for 5 minutes before transferring them to a wire rack. This step ensures they hold their shape while staying delightfully tender.
