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.

Can I sustitute the collagen with wey protein, in stead of adding more almond flour?
I have a Cosori AF. I preheated at 310 as directed. I cooked for 9 minutes and found center was still gooey. Cooked for 2 more minutes. Hoping it will set up! I am at sea level in California. Has this ever happened to you? I absolutely love your recipes and appreciate the work you put into each and every one!
I have the exact same air fryer and haven’t had issues… Did you use a different sweetener? What kind of collagen did you use?
This was just what my husband and I needed this morning!! Foggy PNW morning with just the perfect fall chill. This morning called for a chocolate fix, and this was perfect!! Thank you for sharing this hunk of gooey perfection!! Your recipes have never disappointed us!!
Hello,
Question? Guess we can make 4 individual cookies correct instead of cutting it into quarters. Ty
Yup!
My toaster oven has a convention oven feature. Would it give the same or similar results?
Hard to say but worth a shot. Keep your eye on it while it bakes!
Carolyn,
Thank you for including oven baking instructions, as not all of us have an air fryer. And collagen peptide substitute as well. You are very thoughtful. <3
I’ve made this several times. Love the taste and texture. I cut it and freeze to take out when I need a yummy treat!
Hello….Could I use vanilla collagen or unflavored?
Yes!
is there any sub for the collagen?
Please read the blog post! 🙂
I apologize for not reading thoroughly! I found the substitute!
Great!
I’m not familiar with collagen peptide products. What brand and where in grocery do I find it
Pam
Hi Pam… I usually purchase mine online, although you can often find it in the health food and supplement aisle of most grocery stores.
I just want to know if you can leave out the peptides?
Please read the blog post! 🙂
I have an air fry option on my oven. Would that work the same? Or do I need to use one of the smaller air fryers. I have one but I keep it inside it’s box so it doesn’t get dirty, but it also keeps me from using it. lol.
It should work but you may need to adjust the baking time. Please keep an eye on it in the oven.
Perfect for when it is too hot to turn on the oven for baking!
