Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a large mixing bowl, mash the ripe bananas until smooth.

Add softened butter, brown sugar, and granulated sugar to the bowl. Mix until well combined and creamy.

Beat in the egg and vanilla extract until fully incorporated.

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

Gradually add the dry ingredients to the banana mixture, stirring until just combined.

Gently fold the chocolate chips into the cookie dough.

Use a cookie scoop or tablespoon to drop dough onto the prepared baking sheet, spacing them about 2 inches apart.

Place in the preheated oven and bake for 12-15 minutes, or until the edges are golden brown.

Remove from the oven and let the cookies cool on the baking sheet for 5-10 minutes before transferring them to a wire rack to cool completely.
