  • 1/2 cup sour cream
  • 1 stick (1/2 cup) butter, softened
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar
  • 1 egg
  • 2 teaspoons vanilla extract
  • Optional:
    • 1/2 cup mini chocolate chips
    • 1/2 cup walnuts, chopped


  1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
  2. Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.
  3. Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
  4. Add Wet Ingredients: Beat in the mashed bananas, sour cream, egg, and vanilla extract until well combined.
  5. Incorporate Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
  6. Fold in Mix-Ins (Optional): If desired, gently fold in the mini chocolate chips and chopped walnuts until evenly distributed throughout the cookie dough.
  7. Scoop and Shape: Using a cookie scoop or spoon, drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.
  8. Bake: Bake the cookies in the preheated oven for 10-12 minutes, or until the edges are lightly golden brown.
  9. Cool: Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
  10. Enjoy: Once cooled, serve these NYC style chocolate chip cookies with a glass of milk or your favorite hot beverage for the perfect sweet treat!

Cook Notes:

  • Mashed Bananas: Make sure to use ripe bananas for the best flavor and sweetness. Mash them well with a fork or potato masher until smooth.
  • Sour Cream: The sour cream adds moisture and a subtle tanginess to the cookies, resulting in a soft and tender texture.
  • Mix-Ins: Feel free to customize these cookies with your favorite mix-ins. Aside from chocolate chips and walnuts, you can also add dried fruits, coconut flakes, or even candies for a fun twist.


  • Banana Nut Cookies: For a nuttier flavor, increase the amount of chopped walnuts or add additional nuts such as pecans or almonds to the cookie dough.
  • Banana Chocolate Chunk Cookies: Instead of mini chocolate chips, use chopped chocolate chunks or chunks of your favorite chocolate bar for larger pockets of melty chocolate in every bite.
  • Banana Oatmeal Cookies: Add a cup of old-fashioned rolled oats to the cookie dough for extra texture and fiber. You can also sprinkle some oats on top of each cookie before baking for a rustic look.

Keto and Low-Carb Versions:

Unfortunately, due to the nature of this recipe and the use of bananas and sugars, it may be challenging to create a true keto or low-carb version without significantly altering the taste and texture of the cookies. However, you can experiment with alternative sweeteners such as erythritol or stevia for a lower carb option, and use almond or coconut flour in place of all-purpose flour. Keep in mind that the results may vary, and the cookies may not have the same texture as the original recipe.

These NYC Style Chocolate Chip Cookies with a banana twist are a delightful departure from the traditional chocolate chip cookie recipe. With their soft and moist texture, subtle banana flavor, and pockets of melty chocolate chips, these cookies are sure to become a new favorite in your household. Whether you enjoy them as an afternoon snack, dessert, or with your morning coffee, these cookies are guaranteed to satisfy your sweet cravings. So, why not whip up a batch today and treat yourself to a taste of cookie perfection?
