These chocolate chip cookies are crisp, chewy, and loaded with a couple of surprise ingredients make them extra delicious.

In the world of baking, there are few things as hotly debated as the perfect chocolate chip cookie. This recipe, from my friend Carrie, is certainly in the running. The first time she sent it to me, I remember thinking, Wow, she really threw everything in there. But Carrie is a fantastic baker, so I gave them a try—and now they’re one of my favorite chocolate chip cookies.
The secret? Actually, there are two. The first is oatmeal, ground into a fine powder so it adds just the right amount of chewiness without tasting like oatmeal cookies. The second is coconut. I know it sounds a little strange. But trust me: you can barely taste it, and it somehow makes the cookies richer, chewier, and even more irresistible.
“Such a great recipe—I try all different kinds of chocolate chip cookie recipes and this one is definitely at the top!”
What You’ll Need To Make Secret Ingredient Chocolate Chip Cookies

- Old-Fashioned Rolled Oats: Adds a subtle nutty flavor and chewy texture when ground.
- All-Purpose Flour: Provides the structure for the cookies. Measure by spooning it into the measuring cup and leveling it off to ensure accuracy.
- Baking Powder & Baking Soda: Helps the cookies rise and ensures even browning.
- Butter: Provides richness and moisture.
- Granulated Sugar & Light Brown Sugar: Adds sweetness and a hint of molasses flavor.
- Large Egg: Binds the ingredients together and adds moisture.
- Vanilla: Enhances the flavor of the cookies with its aromatic richness.
- Semi-Sweet Chocolate Chips: Provides rich chocolatey bites throughout the cookies.
- Sweetened Flaked Coconut: Adds a touch of sweetness and chewy texture.

Step-By-Step Instructions
Step 1: Blitz the flour and oatmeal. To begin, place the oatmeal in the bowl of a food processor or blender. Process until finely ground.

Step 2: Combine the dry ingredients. In a medium bowl, combine the ground oats with the flour, baking powder, baking soda and salt. Whisk to combine and set aside.

Step 3: Cream the butter and sugars. In the bowl of an electric mixer, combine the butter, granulated sugar and brown sugar. Beat at medium speed until light and fluffy, about 3 minutes.

Step 4: Add the egg and vanilla. Beat well to combine.

Step 5: Add the dry ingredients. Add the flour mixture to the bowl and beat at low speed until just combined.

Step 6: Mix in the add-ins. Add chocolate chips, coconut and nuts and mix well.

Step 7: Form dough balls. Working with 1½ tablespoons of cookie dough at a time, form balls and place on parchment-lined cookie sheets, leaving at least 2 inches between them.

Step 8: Bake. Slide the baking sheet into the oven and bake until edges of cookies begin to crisp but centers are still soft, 12 to 14 minutes.

Step 9: Cool and enjoy. Cool cookies on baking sheets for 1 minute, then transfer to racks to cool completely.

WOW! Absolutely delicious. Followed recipe as written except baked in convection and didn’t rotate pans. We finally got a chocolate chip cookie that didn’t go flat. This will definitely be our go to chocolate chip recipe from now on. LOVE your recipes Jen!
I needed a cookie recipe for a batch I was making as a gift and this seemed to fit the bill as something a little different from standard chocolate chip cookies. Not only did this cookie turn out delicious with a great texture (quality control, y’know) but the cookies were also attractive without added attention. Typically, I often need to “pat” my drop cookies with my spatula a little past being halfway done in order for them to cook evenly but these cookies baked perfectly without that treatment. I will certainly be making these again!
I love all Jennifer’s recipes, but please.. the thing I love best is that I can print them out on ONE sheet of paper.. don’t change that metric.
Glad you like the recipes! I try to be cognizant of how much space the recipes will take up paper-wise but sometimes it’s just not possible to limit the recipe to one page. I’m not sure if you use the double-sided option, but I always print that way to cut down on paper waste.
I’ve made these twice, one with coconut and one without. Both taste great. The crunchy yet chewy combo is the best! I believe this has become my go to chocolate chip recipe.
I made these today for my husband who is Gluten Intolerant. He LOVES them. I used Grandpa’s GF flour and the rest of the recipe as written. I may have put a little less flour as the GF seems to take less than regular flour. I made big cookie balls from my large ice cream scoop. Froze the balls. Baked the frozen balls for 15 minutes and they are fantastic. My husband said it is the best GF cookie he has ever tasted. Thank you!!!
I’ve always enjoyed baking and have collected and tweaked recipes over the years. This recipe with coconut flakes is very similar to a recipe I have at home. For my cookie recipe, I tend to use margarine or regular butter and bake it longer to make it crispier.
What does the unsalted butter do in baking? Does margarine make cookies crispier for crisp cookies?
I made your recipe as is and the chewy cookie lovers enjoyed it. What temperature and time to I bake to make it crispier?
Thank you.
Hi Tayrumi, The primary reason that recipes call for unsalted butter is that the amount of salt in salted butter varies by brand. This makes it harder to calibrate the rest of your seasoning in the recipe. I never bake with margarine so I don’t know if it would make crispier cookies. You could bake these for another minute or two to get them a little more browned but if you want a really crispy cookie, I’d recommend this recipe.
Such a great recipe— I try all different kinds of chocolate chip cookie recipes and this one is definitely at the top! The coconut and ground oats really give it the great texture and sets it apart from traditional CC cookies. My husband loves these and he’s not a sweet tooth. Thank you again! Time to buy your book!
Hi. I have made these often and they are always excellent and well received! I am about to make them again, but have question: The coconut I have on hand is Baker’s which is what I usually use, and has been in the refrigerator (opened but in an airtight container) for almost a year … I tasted it and it seems ok, but maybe dry. Is it still OK to use it? I am about to leave my current residence for a number of months and don’t want to buy a brand new bag. Just not sure what to do. Thanks!
Hi Jane, I can’t say for sure, but I suspect it will work. Please LMK how they turn out!
Hi. A neighbor gave me fresh coconut so I didn’t have to use my old stuff. Just letting you know I never had to find out if it worked well! Thanks for your advice.
Problem solved!
I actually had a similar issue- coconut dried up in the fridge. I just threw it in the food processor so there wouldn’t be large dry pieces of coconut in the cookies!
Haven’t tried to bake these cookies yet as my dough is dry and crumbly — it dawned on me that it has to be the flour, Canadian vs American as there is a difference. Is there a fix to make the dough stick together?
Hi Helen, the dough can be a bit dry and crumbly after being refrigerated. I’d let it warm up just a bit as that may help. Also, there’s a chance you may have used too much flour. Did you use the spoon and level method to measure the flour? Even a few extra ounces can make a big difference. This article/video explains it nicely. (I don’t think any differences in Canadian flour would’ve had an impact on the dough.)
Hi Jenn,
Wondering if I can brown the butter for this recipe to give it more depth of flavor. Love your recipes.
Thanks,
Sue
Hi Susan, I don’t think it will work here as the butter still needs to be solid. Sorry1
I brown my butter and allow it to sit to cool completely and it works great and does give it extra flavor
