This low carb cinnamon cereal is the perfect keto breakfast when you’re sick of eggs and missing the texture of cold cereal on a low carb diet! Make a big batch and you’ll have this delicious keto cinnamon cereal on hand whenever the craving hits!

I’ve been kicking this low carb cinnamon cereal recipe idea around for a few weeks now. It all started when I was pouring my son a bowl of his favorite “treat” cereal one morning, and it smelled so good that I suddenly missed eating cereal. DESPERATELY.
The cold, creamy milk mixed with the sweet crunch of the little squares just sounded amazing to me right then. I didn’t cave and eat any, but I added a low carb cinnamon cereal recipe to the top of my “to do” list!
This morning I finally had time to do some experimenting with it so I got to work.
Because I’m doing the Whole 30 in August and the only approved sweetener is the occasional fruit or fruit juice, I wanted to develop a low carb cinnamon cereal recipe that would also be Whole 30 compliant.

As it is, I’m giving up my beloved Cream Cheese Pancakes, because you can’t have dairy on the Whole 30 – which also rules out another of my favorites, Greek yogurt.
On top of that, I can’t have bacon or sausage unless I make my own, or pay through the nose for one cured without any sugar at all. So I’m going to be seriously hating eggs by the end of the month!
Or at least I would be if I didn’t have this awesome keto cinnamon cereal recipe to add to my breakfast menu! Served with unsweetened almond milk, it’s pretty amazing, and stays crunchy for about as long as a typical breakfast cereal.

For those of you not doing the Whole 30, this low carb cinnamon cereal recipe can be sweetened with the sugar substitute of your choice – just remember to add 1/2 cup of water to replace the liquid from the apple juice. Start with the equivalent of 1/4 cup of sugar when figuring out your measurements and go from there to get it as sweet as you prefer.
This keto cinnamon cereal recipe is pretty easy to make too, which is an added bonus.
On another note, good quality cinnamon will really make a difference. You don’t have to buy an expensive brand but if your cinnamon jar is from the 90’s, it’s time to throw it out and buy some fresh stuff.
You should really be replacing your dried herbs and spices at least once a year because they lose their potency over time.
Cinnamon Faux-st Crunch Cereal – Low Carb and Gluten Free
- Yield: (6) 1/2 cup servings
Ingredients
- 1/2 cup milled flax seed
- 1/2 cup hulled hemp seeds
- 2 Tbsp ground cinnamon
- 1/2 cup apple juice
- 1 Tbsp coconut oil
Instructions
- Combine the dry ingredients in a Magic Bullet, blender or food processor. Add the apple juice and coconut oil and process until fully combined and mostly smooth.
- Spread the batter out on a parchment lined cookie sheet until nice and thin – about 1/16 of an inch thick. Bake in a preheated 300 degree (F) oven for 15 minutes. Lower the heat to 250 degrees (F) and bake for another 10 minutes.
- Remove from the oven and using a pizza cutter or knife, cut into squares about the size of the keys on your computer keyboard.
- Turn off the oven and put the cereal back inside for about an hour, or until it’s crisp and breaks easily. If it’s still soft, keep in the oven until completely dried out and crisp.
- Serve with unsweetened almond or coconut milk! SO good! Can’t wait to hear what you guys think of it!

I haven’t had Cinnamon Toast Crunch in ages but from what I remember, the taste of this comes pretty close. I used three tbsps of Swerve mixed with ½ cup of water instead of apple juice and had to bake it for much longer at 300 degrees to get that crunchy texture.
Notshyla says
How???? Mine tastes like dirt. What are you all doing that makes its so sweet and yummy tasting?
Marissa says
I made these last week and loved them! I was gonna make another batch just like it today, but then I got a chocolate craving, so I added cocoa powder and a half a scoop of chocolate Jay Robb protein to the batch. They are making my home smell lovely right now, I’m hoping they taste as good as they smell! I’ve missed my Cocoa Puff cereal (it’s been probably 6 years since I ate it). Maybe this will do the trick :D

Thank you for sharing this recipe. I used unsweetened apple juice. (I’ve been off sugar and sweeteners for over a year.) I was surprised it wasn’t sweet enough, so I added 1 tablespoon of organic honey and it turned out great. I wanted to share the feedback with anyone who may need the sweet boost. They’re finishing up baking now, and I love the way my house smells! Thanks again for taking the time to share this.
Christina says
Oh and obviously I sweetened it with something, not just lemon juice- blech can you imagine! I only had a little bit of stevia left (1 packet) and was out of erythritol so I just used coconut sugar. It’s still lower-carb and grain free, and all the healthy fat and fiber will help slow down that sugar. :)
Christina says
Cereal used to be one of my biggest downfalls once upon a time. I made this recipe tonight and holy crap is it ever good! Instead of apple juice I just used a mixture of water and fresh lemon juice, to which I also added a bit of vanilla extract. I kind of doubled the recipe and added in psyllium husk just because I felt like it. I can’t wait to eat it tomorrow morning with my almond milk- I’m really impressed! This would even make a delicious cookie recipe. You found such a perfect application for ground flax- drying the heck out of it and making it crunchy!!! Genius! Thanks for posting the recipe. Definitely going to be making this on a regular basis from now on. Also, quite easy on the pocket book… adding psyllium stretches out your ingredients a bit.

I’m not a big cereal fan (as far as eating it with milk etc), but I love to snack on it dry. Always looking for new grain-free ideas and was happy to come across this. It’s in the oven drying right now. I added pinches of nutmeg, ginger, cloves to it (simply because I love all those spices together with cinnamon!). I wished I read through the comments first…. Loved the suggestion of adding a little bit of salt to help bring out the flavors, so next batch will have just a tiny sprinkling of Celtic sea salt added. Thank you for this recipe!
Nelson says
Has anyone had success with using a hemp seed alternative and how did it come out? I saw one person used sunflower seeds, but the cereal didn’t come out crispy.
Arlene says
I can’t seem to get the bits to crisp up. I’ve let them sit and even heated up the over again, but the bits are still soft.
Any suggestions?
Thanks
Mellissa Sevigny says
Sorry Arlene I’m really not sure, not knowing exactly how you made them. Did you deviate from the recipe at all, and if so how?
Arlene says
Thanks for responding so quickly. I used all of the required ingredients but substituted the water for the apple juice. The consistency was perfect and I had no trouble spreading and cutting the bits.
I may try heating them again on a little higher heat.
Jana says
This was perfect. I did use the water/sweetener version, and I am in love. Thank you so much. It’s such a treat to be able to have cereal… my house smelled lovely while it was baking and my tummy and heart are happy. Thank you so much.
Jana says
Sorry to maybe overuse the “thank you so much”, but I don’t know how else to word it. :) I’m very appreciative.
judy says
Can’t wait yo try this. I have golden flax seed meal. Is that OK for the flax seeds? I have tried some of your other recipes, and enjoyed them very much. Thanks!
Mellissa Sevigny says
Yes, golden flax meal will be perfect!
