How To Make Banana-Walnut Chocolate Chunk Cookies
A step-by-step guide to these wonderfully soft, chewy, and loaded cookies.
- Prep Oven and Dry Ingredients: Preheat the oven to 375°F. Line two baking sheets with parchment paper. In a small bowl, whisk together the all-purpose flour, whole-wheat flour, salt, and baking soda.
- Cream Butter and Sugars: In the bowl of an electric mixer fitted with the paddle attachment, beat the softened butter and both sugars on medium speed until the mixture is pale and fluffy.
- Mix in Wet Ingredients: Reduce the mixer speed to low. Add the egg and vanilla and mix until just combined. Mix in the mashed banana.
- Combine Dough and Fold in Mix-ins: Gradually add the flour mixture and mix on low until just combined. Use a rubber spatula to stir in the oats, chocolate chunks, and toasted walnuts until they are evenly distributed.
- Scoop and Bake: Using a 1 1/2-inch ice cream scoop (about 1.5 tablespoons), drop the dough onto the prepared baking sheets, spacing them about 2 inches apart.
- Bake and Cool: Bake for 12 to 13 minutes, rotating the sheets halfway through, until the cookies are golden brown and just set. Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.

Recipe Tips
For the perfect, chewy, and flavor-packed banana cookie.
- How to get the perfect chewy texture? The key is to not overbake them. Pull the cookies from the oven when the edges are golden but the centers still look soft. They will continue to firm up as they cool on the hot baking sheet, resulting in that wonderful chewy texture.
- Why use very ripe bananas? The best bananas for baking are the ones with lots of brown spots! They are much sweeter, have a more intense banana flavor, and provide a lot of moisture, which is essential for the soft texture of these cookies.
- Can I use a different nut or chocolate? Yes, absolutely! Toasted pecans are a fantastic substitute for the walnuts. You can use milk chocolate or dark chocolate chunks instead of semi-sweet, depending on your preference.
- Why toast the walnuts? Toasting nuts for a few minutes in a dry skillet or in the oven before chopping them is a quick step that makes a huge difference. It deepens their nutty flavor and gives them a crispier texture.

FAQs
Yes, this cookie dough is great for making ahead. You can cover and refrigerate the dough for up to 2 days. You can also scoop the dough into balls, freeze them solid on a baking sheet, and then store them in a freezer bag for up to 3 months. Bake from frozen, adding an extra 2-3 minutes to the bake time.
A cakey texture in these cookies is usually the result of having too much moisture, often from using a very large banana. For the best consistency, it’s a good idea to measure the mashed banana to ensure you have about ½ cup.
