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’ve made this recipe twice now. I can’t seem to get the middle fully cooked. It doesn’t firm up at all, even when fully cooled. I even gave it more time in the air fryer. The outer edge that does get fully cooked and firm tastes AMAZING! I just can’t figure out what else to do. I read the entire blog post. I’m using the bake setting on my air fryer. The sweetener I’m using is Splenda Magic Baker Brown (erythritol, allulose, molasses, glycerin, stevia leaf extract). Any ideas?
Aha! Thank you for telling me what kind of sweetener and the ingredients… it’s the allulose. It makes things much softer than other sweeteners. I recommend adding an additional tablespoon of almond flour to help firm it up, baking a bit longer too. Maybe even a bit of xanthan gum would give it more structure.
Oh I never thought of that. Thank you!
I love this so much! Could you please advise how to transition from sugar alcohols to a granulated pure stevia or monk fruit (no erythritol) because I don’t think I can live without these!
These REALLY ARE THAT GOOD!! Just follow the directions and let it cool completely before trying to eat it! Perfect cookie texture and taste!!
Glad you enjoyed it!
Wish I could give this recipe 10 Gold Stars. It truly is the absolute BEST tasting cookie. It is perfectly soft on the inside yet it has a nice crunch on the outside. The 4 serving size is perfect for my sister and I to share. We have 1/2 one day and the other 1/2 a day or two later and it is delicious 😋.
Thank you Carolyn for creating this a Fabulous Cookie Recipe!!

Thank you!
I am known in my family for my (non-keto) chocolate chip cookies. They are my most requested item to bring to family events, so my standards are high. I have come to realize that you simply cannot expect to duplicate non keto baking and bread, but these are pretty damn good! It did take 15 min in the air fryer. It was too soft to remove from the air fryer without ruining it, so I put the whole air fryer basket in the cold garage for 5 minutes. Perfect! Still a bit gooey but easy to handle. I have tried about 4 different cc cookie recipes since going keto and these beat the others by a mile! Another home run, Carolyn 😊
I think we must have VERY different air fryers. What brand is yours?
Instant Pot Vortex Plus 6QT
Made these again today in the oven using a cookie scoop. Double recipe made about 18 cookies. 14-15 min if you like them soft. The air fryer version had a more gooey center, but both were good
Can I use a faux egg instead of a real egg
I have no idea but I think it’s worth experimenting!
My son just texted me this picture, he made in his dorm room.(sorry, couldn’t attach the picture 🤷♀️)He made in to two cookies so he could save one for another night. Then he sent another message, “No I’m eating both-they’re incredible! Definitely going to be my go to cookie!
Thank you for the incredible recipes, my son was diagnosed with T1D at 15 and your website has been a Godsend!
I LOVE THIS!!! Thank you for sharing.
Nice treat that quickly comes together. I like the recipe size so that I’m not tempted for many days. Perfect for 2 people!
What can you use if you don’t have collagen peptides?
Gelatin might work. Try 1 tablespoon, but add another tablespoon or two of almond flour.
So good! Thank you!
I’ve made this three times and it gets better every time! Seriously best keto cookie I’ve ever had. I vote more air fryer cookie recipes! 🙂
After taking out of the air fryer center a little bit soft so Carolyn suggested putting in the icebox and I did and omg this cookie was beyond yummy
Made this tonight for our dessert and it was delicious. I used the convection option on the oven and cooked for the 15 minutes on 325. I also used high broil for a few minutes just to get the top of cookie browned. Yummy ! We all loved it with some carb smart vanilla ice cream. Thank you for another great recipe!,
This is by far the best chocolate chip cookie recipe. Don’t get me wrong, all Carolyn’s recipes are great, but this one is truly the best all round chocolate chip cookie!!! Ty!
Just tried this. With so few ingredients, it’s a snap to make. It totally tastes like what you expect a chocolate cookie to taste like.
I ended up making 4 cookies instead of a giant one. The dough is a bit hard to handle, so you have to shape it with your fingers on your cooking surface. But the cookies hold together beautifully once they are cooled.
I used my Ninja Air Fryer oven at the bake setting, and it took much longer. I eventually turned up the temperature to 340 and watched them like a hawk.
Looking forward to more variations!
Excellent recipe, I have made this recipe three times this week and the last time I did not put chocolate chips, but I added some nutmeg, molasses, and ginger and it was like having a tea cake! I love this recipe! Last week I made a mistake and bought a box of Stroopwaffle and I ate four of them in one day and it gave me the worst headache from having real sugar… This recipe came to my inbox right on time! Thank you so much!
