Keto Cookie Crisp Cereal

This keto cookie crisp cereal is sugar free and takes me right back to childhood. I make it as a breakfast treat or an after-dinner bowl with cold almond milk.
I started making this because I missed the real thing. Growing up, Cookie Crisp was my go-to Saturday morning cereal, and when I went keto I figured those days were over. Turns out they weren’t.
This recipe uses almond flour and coconut flour as the base, with butter doing all the binding. No eggs needed. I tested a version with egg early on, and the cookies puffed up like little pillows instead of staying flat and crunchy. Butter alone keeps them thin enough to hold their shape in a bowl of milk without turning to mush.
The sweetener choice matters more than you’d think. I use a monkfruit blend because erythritol-based sweeteners recrystallize once they hit cold milk, creating a gritty, sandy texture. I noticed this the first time I tried straight erythritol. Monkfruit blend stays smooth and the cookies keep their crunch longer in the bowl.
Making these is straightforward. Mix the dry ingredients, cream the butter and sweetener, combine everything with sugar-free chocolate chips, then refrigerate the dough for 30 minutes. That chill time is non-negotiable. I tried skipping it once and the dough spread flat on the pan instead of holding its marble shape. After chilling, roll tiny balls (marble-sized), press them slightly flat, and bake at 350 for 6-8 minutes. Mine are usually done closer to 7. Let them cool completely on the baking sheet before handling. They’re fragile when warm and will crumble if you pick them up too early.
Pour cold almond milk or heavy cream over the top and eat them with a spoon. Macadamia nut milk and coconut milk work too. The crispy outside softens just enough to absorb some milk while the center stays chewy. It’s the same experience I remember as a kid, just without the sugar crash.
The sugar-free chocolate chips pull a lot of weight here. I use Lily’s or ChocZero, both of which melt slightly during baking and create little pockets of chocolate throughout each cookie. You can leave them out for a plain vanilla version, but I think the chocolate is what makes this taste like the real thing.
If you like this style, my almond flour cookies use a similar base dough in full-size form. And my no-bake cookies are another option when you don’t feel like turning on the oven.
I keep a jar of these on the counter for snacking too. They’re good on their own, straight out of the container. My kids grab handfuls after school and have no idea they’re low carb. When I want more of a dessert, I put a scoop of low-carb ice cream in the bowl with the cookies and milk. That’s my Friday night setup.
One thing I want to be clear about: this recipe is naturally egg-free. That wasn’t accidental. I tested it both ways and the egg version lost the crispy cereal texture I was going for. If you’re avoiding eggs, this is one of the few keto cookie recipes where you don’t need a substitute because eggs were never part of the formula.

Ingredients
1 ½ cups almond flour -
1/4 cup coconut flour

3/4 cup unsalted butter, softened
-
1/2 cup monkfruit blend sweetener
-
1 teaspoon vanilla

1/2 cup sugar free chocolate chips
Step by Step Instructions
Step by Step Instructions
Dry ingredients
Preheat oven to 350 degrees. Sift together almond flour, coconut flour and salt in a small bowl. Set aside.
Wet ingredients
In a medium bowl, cream together butter, monkfruit sweetener, and vanilla extract until smooth.
Add the chips
Slowly mix in dry ingredients to the wet ingredients, along with the sugar free chocolate chips.
Refrigerate
Mold dough into a disc shape and wrap with plastic wrap. Refrigerate for at least 30 minutes. This allows the flavors to come together and prevents the cookies from spreading while baking.
Make mini cookies
Pinching off a small amount of cookie dough, roll dough into a ball about the size of a marble. Place ball on a parchment lined baking tray and press down flat to form a cookie shape. Repeat with remaining dough, spacing around a ¼ inch apart. Bake at 350 degrees for 6-8 minutes or until the edges of the cookies begin to brown slightly. Remove from the oven and let cool on the baking tray for 3-5 minutes before transferring to a cooling rack. Let cool completely before handling and pouring milk over your keto cereal.

Can I freeze the baked cookies or the raw dough?
I freeze both regularly. Baked cookies go in a freezer bag for up to 2 months. I freeze them in a single layer on a sheet pan first so they don't stick together. Raw dough balls freeze just as well. I add a couple extra minutes to the bake time when cooking from frozen. Either way works, but I usually freeze baked ones since they're ready to pour milk over right after thawing.
Why do I need to refrigerate the dough? Can I skip that step?
I tried skipping it and the dough spread flat on the baking sheet instead of holding its shape. The 30-minute chill firms up the butter so the cookies keep their tiny marble shape during baking. I've pushed it to 20 minutes when I'm impatient and that works in a pinch, but anything less and you'll end up with flat discs instead of little cookie balls.
Can I make these in an air fryer?
I've done it at 325 degrees for 5-6 minutes and they come out great. I use a piece of parchment in the basket so the cookies don't fall through the grates. My air fryer runs a bit hot, so I start checking at 4 minutes. The edges crisp up faster than in the oven, so keep a close eye on them.
Which sweetener keeps the cookies crunchiest once I pour milk over them?
Monkfruit blend, hands down. I tested straight erythritol and it recrystallized once the cookies hit cold milk, creating a gritty, sandy texture. Allulose also works well and stays smooth. I've stuck with monkfruit blend because it behaves the best in both the dough and the bowl.
Are these cookies egg-free?
Yes, and that's intentional on my part. I tested a version with egg and the cookies puffed up instead of staying thin and crispy. Butter alone binds the dough and keeps the cookies flat enough to work as cereal. If you're avoiding eggs for allergy reasons, this is one of my few cookie recipes where you don't need any substitutes at all.
How many net carbs per serving?
My batch makes about 40 mini cookies. A serving of 8-10 cookies (about one cereal bowl's worth) comes out to roughly 3-4g net carbs depending on which chocolate chips I use. I use Lily's, which keeps the count lower than most brands.
Can I use a different flour instead of almond and coconut flour?
I've only tested this recipe with almond and coconut flour together, and that combo gives the best texture in my experience. Hazelnut flour works as a swap for the almond flour if you prefer the flavor, but it changes the taste noticeably. I wouldn't swap out the coconut flour since it absorbs moisture differently and my ratios would need adjusting.
Can I make this recipe dairy-free?
I haven't tested a fully dairy-free version of this exact recipe, but coconut oil should work in place of the butter. The cookies will be slightly less rich. I'd go with refined coconut oil so you don't get a strong coconut flavor competing with the chocolate chips. For the cereal milk, I already use almond milk most of the time, so that part is naturally dairy-free.
One thing I figured out: the dough needs a full hour in the fridge, not just the minimum 30 minutes. Mine used to spread thin and merge together on the pan, but that extra chill time keeps them as distinct little cookies. Makes a big difference in the final bowl.
The spreading is all butter temperature. An hour in and they hold that tiny marble shape way better. I should update the recipe notes.
If the dough keeps sticking to your hands while you're rolling, chill it an extra 30 minutes past what the recipe calls for. Found this by accident (left the disc in the fridge while I cleaned up) and came back to dough that rolled into perfect little balls with zero resistance. Also: swap in Lily's dark chocolate chips if you have them. The slight bitterness cuts through the monkfruit sweetness and suddenly these taste like a real cookie, not a keto approximation of one. Five batches in and I'm still kind of in disbelief that a bowl of these in cold almond milk holds up the way it does. Crunchy until the last spoonful.
The extra chill makes total sense. Warm butter starts spreading the second the dough hits your hands, and the last cookies you roll are always the worst ones. And that last-spoonful crunch still gets me too.
Used Lily's dark chocolate chips and chilled the dough overnight instead of just an hour, and the cookies came out SO much crispier. If you want that actual cereal snap, the extra time in the fridge is worth it.
Switched to Lily's 70% dark chips on batch four and the bitterness cuts through the monkfruit in a way the regular chips don't.
Batch four and you found something I missed. I've been defaulting to the regular chips but that extra bitterness makes sense with monkfruit. Switching.
I kept putting this off for months picturing a thousand tiny cookies, then finally caved on a snow day last week. Dough came together faster than I expected (creaming the butter first makes it really easy to handle), and the house smelled amazing when they came out at 350. Poured a bowl with cold almond milk and had to stop for a second. Tasted exactly like I remembered from childhood. Four stars only because the crunch faded overnight on the counter. Should these be refrigerated between servings, or is there a trick to keeping them crispy?
Counter, not the fridge. Fridge pulls moisture and they go soft faster. I keep mine in an airtight container and they hold up 2-3 days. If they've already softened, 3 minutes at 325 in the air fryer brings them back.
