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.
- Pecans: Introduce a crunchy texture and nutty flavor.

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.

The ground oatmeal & coconut elevate this cookie to something really special. Made a batch, baked some fresh and scooped froze the rest; just as great baked out of the freezer when friends drop by or just a treat.
Great recipe! My favorite chocolate chip cookies!
instead of grinding the rolled oats, can I use instant oatmeal? (the ones that are thinner)
Thanks
Hi Jane, The recipe will work but the cookies will have a slightly different texture than they do with the ground oats.
Made these without the nuts, doubled-up on the chocolate chips and used unsweetened flaked coconut. The BEST!
I’m going to try these for tonight! Looks delish
Hi,
The cookies turned out delicious !
I baked them for only 9 minutes (I never bake cookies longer).
Thank you for the recipe.
Next time I’ll buy rolled oats in advance, and compare.
Thanks again.
I made a mistake right off the bat with these and added regular oats (in flakes, without processing them finely) to the flour mixture before I realized my “woops.” Instead of throwing the ingredients out and starting over, I continued, but added 1/4 C. finely ground pecans (like flour) to the dry ingredients. We also had no chocolate chips, so we took dark Ghirardelli chocolate squares (72% cacao) and chopped them into small chunks/chips to use in place of the chocolate chips. I baked these exactly as directed. These turned out fantastic, although probably denser in texture and not quite as sweet as the original recipe (which I will try in the future to compare). But my husband and I both loved the texture and flavor of these, mistakes and all!
Not sure if anyone has asked; will texture change if unsweetened coconut is substituted? Thx!
Hi Marivic, I think the cookies might end up a little dry with unsweetened coconut.
This recipe sounds amazing and I want to try it but I couldn’t find parchment paper at any of the stores that I went to. Can I use foil or grease the cookie sheet?
Hi William, Just grease the cookie sheet — the parchment is just for easy clean up. Enjoy!
I made these last week. The dough tasted great! The cooked cookies taste great! They are even great frozen (I froze some of the baked cookies in anticipation of my mom coming to visit)! These will now be my go-to recipe for chocolate chip cookies. Thank you Jennifer for sharing the recipe.
I had to omit the pecans as I planned to offer these cookies to a child with nut allergies, and I don’t think it was a great loss, though I love pecans and would try them next time. The cookies were plenty sweet, even though I used only slightly more than a half cup of chocolate chips and *un*sweetened coconut flakes. Unfortunately, the bottoms of the cookies were burnt black after 15 mins. at 350 degrees, even though I rotated the cookie sheets halfway through the baking process. I was surprised that they were overdone, given that my oven usually requires the upper end of the baking time range. Oh well, cookies burnt, lesson learnt (will watch them more closely next time!)
Hi Jenn, That’s strange that the cookies burnt on the bottom. Perhaps your oven is running hot? The only other thing I can think of is that maybe your oven was not fully preheated. Sometimes the initial surge of heat from the bottom of the oven during preheating will burn the bottoms of the cookies before the tops are done.
