Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the egg and vanilla extract until well combined. Then, mix in the mashed bananas.
In another bowl, whisk together the flour, baking soda, and salt. Gradually add this to the banana mixture and stir until just combined.
Gently fold in the chocolate chips, ensuring they’re evenly distributed throughout the dough.
Drop dough by heaping tablespoons onto the prepared baking sheets, about 2 inches apart.
Bake for 10-12 minutes, or until the edges are golden. Remove from the oven and let cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
These cookies are best served warm with a glass of milk or your favorite beverage!
