Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone baking mats to ensure the cookies don’t stick. Mash 2 ripe bananas in a small bowl until smooth and set aside.
In a large mixing bowl, use a hand or stand mixer to beat 1/2 cup softened butter with 3/4 cup packed brown sugar and 1/2 cup granulated sugar until the mixture is light and fluffy, about 3-5 minutes.
Mix in 1 teaspoon vanilla extract and 1 large egg until well combined. Then add the mashed bananas and stir until evenly incorporated.
In a separate bowl, whisk together 1 1/2 cups all-purpose flour, 1 teaspoon baking soda, and 1/2 teaspoon salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Avoid overmixing.
Gently fold in 1/2 cup chopped nuts and 1/2 cup chocolate chips using a spatula.
Using a cookie scoop or tablespoon, drop dough balls onto the prepared baking sheets, spacing them about 2 inches apart. Bake for 10-12 minutes or until edges are golden and centers look set but still soft.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes
Use very ripe bananas with lots of brown spots for maximum sweetness and flavor.
Lightly caramelize brown sugar and mashed bananas in a skillet before mixing for a stronger caramel flavor.
Chilling the dough for 30 minutes can help cookies hold their shape and avoid flatness.
Substitute butter with coconut oil or vegan margarine for a dairy-free version.
