This giant Keto Air Fryer Cookie is my latest dessert obsession. And once you try it, you will be obsessed too! It comes out so perfectly, soft and tender in the center and slightly crisp around the edges. Golden brown, with plenty of melty chocolate chips, and only 2.7 grams net carbs per serving.
I may never make keto chocolate chip cookies any other way again!

Air fryers bake differently than conventional ovens, so it took me a few times to get this one right. But it was well worth the effort – and even the “fails” were pretty darn delicious. I finally hit on the right approach to get that perfect cookie texture, and I was hooked.
Now I want to try it with other recipes like keto peanut butter cookies. Imagine the possibilities! This is the kind of quick dessert that makes the keto lifestyle feel totally effortless.

Why you will love this air fryer cookie
- So easy! This cookie takes about 12 minutes to make, start to finish. And clean is a breeze!
- Perfect texture: Golden brown, with a soft center and crispy edges, this recipe has the ideal chocolate chip cookie texture.
- Phenomenal flavor: This tastes like the cookies of my childhood!
- Small batch recipe: It makes just enough for 4 delectable servings.
- Excellent macros: With only 6.7 grams total carbs and 4 grams of fiber, it’s the ideal keto dessert.
Ingredient Notes

- Almond flour: Choose a finely ground almond flour for the best consistency.
- Sweetener: I really like using my keto brown sugar replacement for the best flavor.
- Collagen peptides: This is part of what makes the texture so perfect! It gives the cookie added gooeyness. If you don’t have it, replace with 2 more tablespoons of almond flour.
- Chocolate Chips: Any brand of low carb chocolate chips should work in this recipe.
- Butter: Melted butter is ideal for chocolate chip cookies, but you could use coconut oil for a dairy-free version.
- Egg yolk: You need one egg yolk for this recipe. I like just the yolk as it makes it more chewy.
- Pantry staples: Vanilla extract, baking soda, and salt.
Overview: How to Make This Recipe

- Combine the dry ingredients: Whisk together the almond flour, sweetener, collagen, baking soda, and salt.
- Add the wet ingredients: Stir in the butter, egg yolk, and vanilla extract until well combined. Stir in the chocolate chips.
- Form the dough: Roll the dough into a ball, place on parchment paper and flatten it.
- Bake the cookies: Set the air fryer to Bake and cook at 310ºF until puffed and golden brown. Remove and let cool completely.

Tips for Success
Most air fryers have a Bake function, which blows the heat less intensely than the regular air fry function. I recommend using this if you have it. If not, try reducing the heat to 300ºF. Keep in mind that different brands of air fryers will bake differently so check on the cookie while it bakes.
If the collagen you use is sweetened, I recommend cutting the additional sweetener back to 2 tablespoons. I love the Perfect Keto Salted Caramel Collagen in this recipe but it can make it overly sweet if you use the full amount of sweetener.
I used a plain square of parchment paper, but I think air fryer parchment liners would work even better. The hot air caused the edges of my parchment to blow upwards, which made my cookie a bit misshapen. Not a dealbreaker but I’d prefer a perfectly round cookie.
No air fryer? You can place the cookie on the parchment on a cookie sheet and bake in the oven at 325ºF. It will probably take 15 minutes.
Sweetener Options: I recommend an erythritol based sweetener for this recipe, as allulose will cause it to brown very quickly. You can certainly use what you like best but you need to know that your results will differ.

I made this cookie and it was incredibly delicious! It’s the best chocolate chip cookie recipe I’ve tasted since starting the ketogenic lifestyle 7+ years ago. I didn’t alter the recipe. My cook time required 4 additional minutes most likely due to my elevation (6,600 ft.). I served 1/8th of the cookie hot out of the air fryer with a scoop of my homemade keto vanilla ice cream. It was very satisfying after dinner. Thank you, Carolyn, for this delicious and quick recipe.
Thanks for the tip on elevation!
Best chocolate chip cookie I’ve had since starting Keto. Crispy on the outside and gooey on the inside. I used an air fryer parchment liner, it was perfect. So easy and quick, dangerously easy…ha ha.
I just grabbed some of those liners myself. I think it will make a difference to the shape of the cookie 🙂
These cookies brought me back to childhood. They are simple perfection in a chocolate chip cookie. The air fryer makes them just the right texture as Carolyn described. We liked them so much I made a second batch and browned the butter first. Outstanding!
Great to hear!
Wow. , you did it again you made a recipe that’s easy to follow put together and is delicious! Thank you so much my cookie looked exactly like yours. I was so thrilled thank you blessings.
Linda
Yay!
I am blown away at how delicious this cookie is.
Perfectly chewy center and slightly crisp edges 🥰 I want the whole cookie, but I’ll behave.
This dropped in my email this morning! Gonna give it a try this afternoon. Hope your heart is healing ♥️
oh my word! easiest and best cookie I ever made, and it was GIANT! I did make one change because I don’t use almond flour anymore. i used Elevate Protien Flour in same measurement as recipie. This cookie was simply amazing! Thank you so much for it!
Cookie was wonderful! Followed recipe exactly as written. Baked in my Ninja Foodi for approximately 16 minutes. Loved it and will make again!
So great to hear!
Agreed. This is the best cookie ever! Love how crispy it is on the outside. I put too much better and added more chocolate chips so the inside wasn’t as cooked but I expected that. Still amazing and will make again!
Yum!
This sounds fantastic. There is just me eating the cookie, so this fast and easy recipe sounds great! Thanks
i made this in the oven and without collagen. A little dry but tasty and quick.
So the lack of collagen definitely affected it. But it also sounds like you over-baked it a bit, if it was dry.
I don’t have any peptides do I really need it or is there a substitute?
I would recommend them, to be honest. It’s much better that way.
Honestly, this is the best keto cookie I have tried. I have the same Corsori air fryer and it came out out perfect. I did turn it over and cook an extra couple of minutes. I haven’t had very good luck with keto baking, you have given me hope This cookie is delicious, even my non-keto family loved it. thanks 😀
So glad you liked it! I am curious… how did you turn it over?
Have you ever used an air fryer liner? They look like really big coffee pot basket liners.
I actually mentioned that in the post… please read it! 🙂
I made this recipe as soon as I saw it. So easy and quick. Perfect for that cookie craving.
Yay, I am so glad you tried it!
This sounds amazing! Going to make one today I hope. I only have chocolate peptides but that ought to make it even more amazing!
