Are you up for a low carb breakfast treat? This super crunchy Keto cereal recipe fits the bill! It’s a sugar free take on the popular cinnamon toast crunch breakfast cereal. This version is gluten free, grain free and tastes delicious.
For many people it’s difficult to wave good-bye to breakfast cereals. But when you’re on a low carb diet, cereal is one of the things that need to go. Whether it’s Kellogg’s or Nestle, cereal is generally made from grains, and grains are high in carbs.
I’m not even going to get started on the high added sugar content of breakfast cereals. Don’t believe a moment when it says it’s “healthy” on the box. The truth is, the only healthy thing about breakfast cereal is the bank balance of the companies who make it. And maybe the cardboard box itself.
Time for the good news. It is really simple to make low carb cereals at home! You replace the grains with nuts and seeds, add a bit of erythritol or your favourite sweetener and let it crisp up in the oven. Strictly speaking, the term “cereal” is misleading, but we’re talking about the “cereal experience” here, and that’s just as good. It’s even better, actually, knowing you’re not filling up on junk right at the start of your day and keeping your blood sugar levels stable.
How to make cinnamon toast crunch Keto cereal – step by step:
2.) Mix your dry ingredients and add them.
3.) This is what Keto cereal dough should look like – crumbly and moist.
4.) Now you scoop it up and form a ball with your hands. Place it between 2 sheets of parchment paper.
5.) Roll out the dough! The parchment paper prevents your rolling pin from sticking. Scatter some more cinnamon and erythritol on top and press it in with your hands so it won’t fall off once baked.
6.) Now you cut the dough into cute little cinnamon toast crunch squares. Last, prick each square with a fork to prevent unnecessarily large air bubbles.
7.) Hello, Keto cinnamon crunch! Wait until the cereal is cooled completely before breaking it into squares.
Tips and tricks to nail this Keto cereal recipe
Roll out the dough nice and thin – this will give a better crunch.
Watch it closely while it’s in the oven. Check after 10 minutes and rotate the baking sheet if the back is getting too brown. Moving the sheet to the lowest shelf can also help. The oven time will vary depending on how thin your “cereal” dough is rolled out.
When you cut the dough, make the incisions wide. This way the squares, which will puff up a little, are easy to separate post-baking. You could also use a ruler to do this as it has a wider edge.
Be patient! All low carb cereals are soft and fragile when fresh out of the oven. They firm up and become crunchy once they’re cold, and this cinnamon crunch is no different. Don’t even think about touching it while it’s still warm – unless you want to sneak a little taste.
Recipe notes and variations
Some Keto cereal recipes use egg whites. I liked the idea of the protein powder, which gives the same protein kick, without having to beat egg whites first.
The psyllium husk powder and the xanthan gum increase the crunch in this recipe and help hold the squares together. You can use ground flaxseed instead (double the quantity as it’s less fine than the psyllium powder), it would do a similar job.
Golden/brown erythritol works well in this recipe, but any granulated sweetener is fine. If you use a different sweetener than erythritol, check the pack and make sure it’s a 1:1 sugar replacement just like erythritol. Some granulated sweeteners are twice as sweet as sugar.
Disclaimer: This recipe contains more erythritol than most of my sweet recipes. Therefore, you do notice that slightly cooling sensation erythritol delivers. But if you want that cinnamon toast crunch cereal experience, it’s gotta be sweet and it’s gotta have that sugary crunch.
If you can’t be bothered with cutting squares, don’t. You can simply break it into bite-sized pieces post-baking!
This recipe is rich and buttery, that’s why your portions don’t need to be large. Serve it with your favourite nut milk or some yoghurt. A few squares would also make a nice sweet treat with a cup of coffee or tea.

Keto Cinnamon Crunch Cereal Recipe
For the topping
- 1-2 tbsp granulated erythritol
- 1 tsp cinnamon
- Preheat the oven to 170 Celsius / 340 Fahrenheit.
- Cut the butter into small pieces and whizz in a food processor together with the erythritol until creamy.
- Mix the dry ingredients in a bowl and add to the butter/sweetener mix. Blend until your dough resembles moist crumbles.
- Form the dough into a ball and roll out thinly between 2 sheets of baking paper. This prevents the dough from sticking to your rolling pin.
- Peel off the top layer of baking/parchment paper and sprinkle the the dough with a topping made from more cinnamon and erythritol. Press the topping onto the dough with your hands.
- Cut into squares with a knife and prick each square with a fork to prevent large air bubbles.
- Bake for 10-12 minutes or until browned.
- Let the cereal cool COMPLETELY before you break it into squares. It is VERY soft when hot but will be crunchy once it's cold.
