Why this Double Chocolate Chip Cookies with Walnuts Recipe Works
With rich chocolate fudge cake mix as the base, every bite is soft, chewy, and packed with gooey chocolate chips and crunchy walnuts. Best of all, they come together in just minutes, proving that bakery-style indulgence doesn’t have to mean hours in the kitchen. Whether you’re baking for family, friends, or simply treating yourself, this recipe delivers comfort and decadence in every bite.
- Ultimate Simplicity: Using a box of cake mix drastically reduces the number of ingredients to measure, often only needing the mix, eggs, and a fat source (butter or oil).
- Fast Prep: The dough comes together in minutes, often in just one bowl, making it perfect for a quick craving or last-minute baking.
- Soft and Chewy Texture: The cake mix base inherently creates a cookie with a super soft, moist, and chewy, almost brownie-like, texture that stays fresh for days.
- Rich Flavor: The combination of chocolate cake mix and extra chocolate chips provides an intense, double-chocolate flavor that satisfies the deepest cocoa cravings.
Why are My Chocolate Walnut Cookies Flat?

Cake mixes often call for oil, which makes batter looser. If you substitute butter and it’s too soft or melted, cookies spread quickly. Do not skip chilling, the fat melts before the cookie sets, causing spreading.
If the oven runs hot, the fat melts before the cookie edges set. Cake mix is already light; overmixing adds air and weakens structure, leading to collapse.

Get the full printable recipe with specific measurements and directions in the recipe card below.

- Chocolate Cake Mix: This is the most important ingredient. It provides all the necessary dry ingredients (flour mixture for structure, sugar for sweetness, cocoa powder for flavor, and chemical leaveners like baking soda for rise) in a pre-proportioned, uniform blend.
- Large Eggs: You need 2 large eggs to make these chewy chocolate cookies.
- Walnuts (Chopped): Adds nutty flavor and crunch. Walnuts add a necessary nutty, earthy flavor that complements the deep cocoa and provide a contrasting crunchy texture to the soft, chewy cookie.
Variations and Substitutions for this Chocolate Recipe
- Chips: Swap out or add to the semi-sweet chocolate chips with white chocolate chips, peanut butter chips, butterscotch chips, dark chocolate chips or mint chocolate chips (for a mint-chocolate variation).
- Nuts: Substitute chopped walnuts with pecans or almonds. You can also omit the nuts entirely.
- Candy: Fold in M&M’s, Reese’s Pieces, or chopped Andes mints/peppermint bark for a festive touch.

Prep Ahead Suggestions for the Chocolate and Walnut Cookie Recipe
You can do several things to prep the chocolate chip and walnut cookie dough in advance. However, this dough comes together very quickly.
- Mix the Dough: The dough can be mixed up to the point of adding the chips and nuts.
- Chill the Dough: The dough is often best when chilled for 30 minutes to 48 hours. Chilling firms the dough, which can prevent over-spreading and result in a chewier, thicker cookie.
- Scoop and Freeze Dough Balls: Pre-scoop the dough into balls and store them in the freezer for easy, on-demand baking.
Alternate Cooking Methods for Fudgy Dark Chocolate Cookies
- Cookie Bars: Press the dough into a greased 9×13 inch pan and preheat oven to 350°f and bake for 20-25 minutes until the edges are set and the center is just barely cooked and has a chewy middle. Cool completely before cutting.
Store, Freezing and Use Leftover Chocolate Chip and Walnut Cookies
- Storing: Room Temperature: Store cooled cookies in an airtight container at room temperature for up to 3-5 days. They stay soft.
- Freezing: Cooled, baked cookies can be frozen in an airtight container or freezer bag for up to 3 months.
- Using Leftovers:
- Ice Cream Topping: Crumble cooled cookies over vanilla or chocolate ice cream.
- Cookie Crumbles: Process them into fine crumbs to use as a crust for cheesecake or as a topping for yogurt parfaits.
- Cookie Sandwiches: Sandwich them with a scoop of vanilla ice cream or a dollop of buttercream frosting.
Common Questions About This Chocolate Chip Walnut Cookies Recipe
Yes, you can absolutely use butter instead of oil in cake mix cookies, but the swap changes both texture and flavor. You can use the same amount as a 1 to 1 ratio.
I love a good macadamia nut in this recipe but you can use whatever nut your family likes to add that crunchy texture.

Expert Tips for Making the Best Chocolate Chip and Walnut Dessert
There are many ways to adapt the basic recipe to make your cookies even better. Check them out below.
- Don’t Overbake: The key to a soft and chewy cookie is to slightly underbake it. The cookies are done when the edges are set and the center is still soft and a little glossy. They will continue to set up as they cool.
- Add a Splash of Vanilla: Even a simple cake mix dough benefits from pure vanilla extract for a more “homemade” flavor.
- For Puffier Cookies: Use a full stick of softened butter instead of melted, and/or add 1-2 tablespoons of flour to the dry cookie mix.
- The Finisher: Immediately after removing the cookies from the oven, gently press a few extra chocolate chips and walnut pieces onto the tops. This is purely for aesthetics but gives a beautiful, bakery-style look.
