Warm, gooey keto air fryer chocolate chip cookies with golden brown edges and soft centers, just 0.6g net carbs. They bake in 6-8 minutes, and I never have to heat up the whole oven.
I started baking these about two years ago, and now this is the only method I use. The circulating heat crisps the outside to a golden brown while the center stays soft and gooey, and a whole batch is done in under 10 minutes. No preheating a full oven.
Why I Bake Cookies This Way
These are egg-free, which surprises people. They’re built like a shortbread, so the butter and almond flour handle all the structure. I’ve had readers tell me they fall apart, and every time it comes down to the same thing: they weren’t cooled completely before handling. I let mine sit on the tray for a full 5 minutes after pulling them out. They’re soft and fragile at first, but they firm up as they cool. Once they set, they hold together even if you stack them.
The dough itself is straightforward. Almond flour, coconut flour, salt, butter, monk fruit sweetener, vanilla, and sugar-free chocolate chips. No egg, no complicated prep. I refrigerate the dough for 30 minutes before baking because it keeps the butter from spreading too fast and melds the flavors together. I’ve tested it both ways, and the chilled batch always comes out thicker with a more buttery taste. You can skip chilling if you’re in a rush, but I don’t recommend it.
The texture is what sets these apart. The outside gets a light crunch from the circulating heat, almost like a shortbread edge, while the center stays soft and melty. They don’t taste like a substitute to me. My kids eat them alongside their regular snacks and have never once asked if these are “different.”
What I love about this method is how forgiving the dough is. It freezes well (I keep frozen balls on hand for weeks), bakes evenly without rotating, and the cleanup is nothing compared to a full sheet pan and oven setup.
If you’ve made my traditional oven-baked version, you know this flavor profile. The air fryer version gives the edges a crispier finish that I actually prefer. For a single serving, try my single-serve cookie (90 seconds in the microwave). And if you want a thicker, chewier result, my best keto chocolate chip cookies use a different flour ratio.
I keep coming back to this recipe because it works on busy nights. Ten minutes to mix, 30 minutes in the fridge, 6-8 minutes to bake. My kids treat it like a normal cookie night (they don’t know these are low carb, and they don’t care). For something even simpler, my 3-ingredient almond flour cookies are a good starting point.
Why I Always Chill the Dough First
It’s not required, but I do it every single time. Refrigerating the dough for 30 minutes hardens the butter so the cookies hold their shape instead of spreading flat. It also lets the flavors come together. I’ve tested it both ways, and the chilled batch tastes noticeably more buttery with better definition around the edges. If I’m planning ahead, I’ll chill it overnight and bake the next day.
How I Tell When Air Fryer Cookies Are Done
This is different from oven cookies. In the oven, I watch the edges. In the basket, I look at the top of the cookie. When the top and sides start to turn golden, they’re done. The center will still look slightly underdone, and that’s exactly what you want. They firm up as they cool on the tray.
Every model runs its own temperature. A reader with a Cosori 5.8qt told me she got dark edges with underdone centers at 350 for the full time, then pulled her second batch 90 seconds early and nailed it. Some Ninja models finish in as few as 4 minutes. I’d check at 5 minutes your first time and adjust from there. Once you know your machine, you won’t have to guess again.
Mix-Ins I've Tried
I keep the base dough the same and swap the add-ins depending on my mood. Pecans and macadamia nuts both work well. I’ve mixed in keto toffee bits for a caramel crunch. A teaspoon of espresso powder deepens the chocolate flavor without adding any coffee taste. Sugar-free white chips are another favorite when I want something different from the usual.
How to Bake These in the Oven Instead
No special equipment needed for the oven version. Place dough balls on a parchment-lined baking tray and bake at 350 degrees for 6-8 minutes. Pull them when the edges just start to turn golden. Let them cool completely on the tray before moving to a wire rack. I’ve done these in the oven plenty of times when my basket was already full, and they turn out just as good.
Storage and Freezer Meal Prep
Nothing beats a warm cookie right out of the basket. But I always make more than I need. Store baked cookies in an airtight container at room temperature for up to 4 days, or in the fridge for about a week. They dry out faster than regular cookies because there’s no sugar holding moisture, so the sealed container matters.
For the dough, here’s what I do: roll it into balls, freeze them flat on a parchment-lined sheet pan until solid, then transfer to a freezer bag. Frozen dough keeps for up to 3 months with no change in quality. When I want fresh cookies, I drop a few frozen balls straight into the basket, add 1-2 extra minutes, and skip thawing entirely. I also reheat already-baked cookies at 300 degrees for 1-2 minutes in the basket or about 5 minutes in a regular oven. Either way, they taste fresh.
More Keto Cookies to Try
I don’t think I could stick with keto long-term without cookies that hold their own against the originals. Here are a few more I come back to.
The basket pushes hot air around the dough from every angle: top, bottom, and sides. It’s essentially a small convection oven with tighter airflow. That concentrated heat is why the outside gets crispy while the center stays gooey, and why the whole batch bakes in just 6-8 minutes. I’ve noticed my cookies brown more evenly this way compared to a standard baking sheet, where the bottoms always cook faster than the tops. If your model has both an Air Fry and a Bake setting, try Bake first. The fan runs at lower intensity, which gives you more control before the edges start to darken. I've tried both and the Bake setting buys about 60 extra seconds before browning kicks in. I use Air Fry mode and it works well, but if your first batch browns too fast, switching to Bake or dropping to 325 degrees is the fix.
Keto Chocolate Chip Cookies in the Air Fryer Ingredients
Step by Step Instructions
1
Preheat
Preheat air fryer to 350 degrees.
2
Sift dry ingredients
Sift together almond flour, coconut flour and salt in a small bowl. Set aside.
3
Mix wet ingredients
In a medium bowl, cream together butter, monkfruit sweetener, and vanilla extract.
4
Add dry ingredients
Slowly stir in dry ingredients and mix until combined. Fold in chocolate chips. Refrigerate dough for 30 minutes to let the flavors meld and keep the butter from spreading while baking.
5
Air fry it
Pinch off a tablespoon of cookie dough and roll into a ball. Place on your air fryer pan (line with parchment paper first if your air fryer only has a wire basket) and press down flat to form a cookie shape. Repeat with remaining dough, spacing about an inch apart. Bake at 350 degrees for 6-8 minutes or until the tops begin to brown slightly. Remove from the air fryer and let cool on the tray for 3-5 minutes before transferring to a cooling rack.

Frequently Asked Questions
Can I make these dairy-free?
I've tested this with coconut oil instead of butter and it works. Use the same amount, make sure it's solid (not melted), and chill the dough a little longer since coconut oil softens faster. The texture is slightly different, a bit more crumbly, but my dairy-free friends have been happy with it.
What does allulose do differently than monk fruit in this recipe?
I've baked this keto recipe with both. Allulose melts more like real sugar, which gives a slightly fluffier, lighter-colored cookie that takes about 2 extra minutes to set. Monk fruit keeps things denser and more shortbread-like, which is what I prefer for this particular recipe. Erythritol works too but has a slight cooling sensation that some people notice. I start with about 3/4 the amount of any substitute and adjust from there.
Can I substitute almond flour with another type of flour?
I've tested sunflower seed flour as a 1:1 swap and it works, but the taste and color are different (sunflower flour can turn slightly green when it reacts with baking ingredients). For a nut-free keto option, that's my recommendation. I wouldn't use coconut flour as a full substitute since it absorbs way more liquid and the ratios would be completely off.
Don’t rush the butter and monk fruit together. I went too fast on the first batch and got a dry, slightly grainy crumb. Creamed it longer the second time and the inside came out the way the recipe describes. Came in skeptical that air fryer cookies would be anything more than almond flour shaped into a round, because that’s what most keto baking has delivered for me over the last two years. This is the closest thing to a real cookie I’ve made in that stretch. My one complaint is the size: a tablespoon of dough makes a small cookie, and one isn’t enough for an actual craving. Two fixes it, still under 150 calories. Four stars because the portion question is real, not because the taste is.
Thank you for the feedback on the size. The tablespoon scoop is what keeps the center soft, so if you roll them bigger I’d add about 2 minutes and pull when the top is just golden, otherwise the outside sets before the middle does. You’re right about the creaming too, I go a couple of minutes on the butter and monk fruit before anything dry goes in.
I calibrated my air fryer for the first time because of this recipe. I run a Ninja that tends to pull hot, so I dropped to 330 instead of 350 and checked at the six-minute mark. First two cookies at a full tablespoon spread flat. Three-quarters of a tablespoon kept the shape. My first time with keto baking, and the monk fruit here is noticeably cleaner than packaged keto stuff, no cooling aftertaste. Texture reads different from a regular chocolate chip cookie, but that outer edge crunch genuinely surprised me. Run one test cookie before committing the full batch, especially if your air fryer runs hot.
The 3/4 tablespoon note is going in the recipe card, Kendra. I’ve had the same thing from other Ninja owners when they drop to 330. And you’re right on the monk fruit. That cooling aftertaste is exactly why I don’t use packets.
Gooey center holds even after an overnight in the fridge. I roll the whole batch, keep them unbaked in the fridge, fry two or three a night when I want something warm. No more reheating stale cookies.
Wasn’t sure the coconut flour texture would fly with my 7-year-old, who has opinions about cookies. She got to them before they cooled and came back with ‘squishy.’ Her word. I’m counting it.
‘Squishy’ from a kid with opinions is a solid review. The coconut flour is what keeps that center soft, it holds moisture differently than almond flour alone.
Pack these in a single layer if you’re transporting them. Centers stay soft, so stacking compresses them. Brought two batches to a neighborhood cookout last weekend and set them next to the actual bakery cookies someone else brought. Watched them go first. When someone asked if they were from the place on Maple Street, I said I made them in an air fryer in under ten minutes. Different reaction than I expected.
Browned the butter before creaming it with the monk fruit and these are in a different league now. The nutty depth pairs really well with Lily’s 55% chips. Also: 10 minutes in the fridge before rolling and the dough handles way better, less spread in the air fryer too. Both changes are worth it.
Yeah, chilling the dough first is something I should have written into the original recipe. Air fryer heats up fast and cold dough buys you time on the spread. Browned butter with Lily’s 55% is a good combo.
Making these for a get-together next Saturday and trying to prep ahead. Can I mix the dough a day or two early and keep it in the fridge, or does the almond flour get weird sitting in wet ingredients overnight? I’ve had nut flour batters do strange things on me before and don’t want to risk it.
Totally fine to refrigerate a day out. This dough firms up cold, so it’s easier to scoop. Roll it into balls before the party and just drop them in the basket when you’re ready.
Subbed in browned butter (cooled to room temp before creaming) and the cookies picked up this nutty undertone I didn’t expect from a 10-minute air fryer recipe. Centers stayed soft, but the flavor just tasted better. Worth the extra step.
The nutty thing comes through harder in almond flour cookies than it does in regular ones. Nothing competing with it. I’ve been on the fence about adding this as an option in the recipe and you just answered the question.
Used Lily’s chips instead of what the recipe calls for and it cut the bitterness a lot. Also figured out that they look underdone when you pull them but if you leave them on the rack for 3-4 minutes they firm up to exactly the right texture.
Ok these are genuinely worth making but I have to flag something for anyone with an air fryer that runs hot (mine is a Cosori 5.8qt): I ran them at 350 for the full time on my first batch and got dark edges with centers that were still somehow a little underdone, which is such a specific air fryer failure mode. Pulled my second batch about 90 seconds early and that was the fix, soft center, just enough color on the edges. The almond and coconut flour together is the right call by the way, way less dense and grainy than when I’ve done straight almond flour cookies in the past. Four stars because I had to figure out my own machine’s timing, which isn’t really a knock on the recipe, more just a reality of air fryer baking that I wish someone had warned me about before my first batch came out looking like it had been through something.
Cosori runs hot, yeah. 90 seconds early is basically the rule with that model. The two-flour combo is exactly why these work – straight almond flour cookies always end up heavier.
I’ve made keto chocolate chip cookies plenty of times in the oven but this is my first time trying them in the air fryer. At 350, are they supposed to look a little underdone when you pull them out? I know oven cookies firm up as they cool but wasn’t sure if the air fryer works the same way.
I have made these several times and they don’t need an egg. When they fall apart, it’s because they haven’t been cooled completely before handling. They have to be cool to the touch. They are similar to a shortbread cookie which don’t have eggs. That being said, you can certainly add an egg, it won’t hurt it.
These are great! Instead of just chilling the dough, I made it into a cookie dough log in parchment paper and put it into a split paper towel core to keep it from flattening on one side. I refrigerated them until they were really solid. It worked like a charm! I was able to slice off a few to cook for a late night snack without having to flatten them at all.This recipe is definitely a keeper! Thank you!
