Soft and chewy banana bread cookies with dark chocolate chips and walnuts. You can enjoy all the flavor of banana bread in a fraction of the time! These are seriously addictive and such a fun alternative to banana bread.
Combine the cool just melted butter and brown sugar in a large bowl and mix to blend. Add mashed banana and mix to combine. Add the egg yolk and vanilla extract and mix well.
Add the salt, baking soda and cinnamon to the banana mixture and stir to blend well. Then, add the flour and fold it in until combined. Add chocolate chips and walnuts and fold them in evenly. Cover the bowl and refrigerate the dough for 1 hour.
Preheat the oven to 350°F. Line two large cookie sheets with parchment paper.
Use a 1.5 oz cookie scoop to scoop up dough and release it onto prepared baking sheets spacing them at least 2 inches apart. Press a few extra chocolate chips onto each dough ball if desired. Bake for 10 to 12 minutes until the edges are golden and the middles are just a bit soft. Let cool for 2 minutes on the baking sheets and then transfer cookies to a wire rack to finish cooling.
