Our Keto Cinnamon Toast Crunch recipe is light, sweet, and has all that cinnamon sugar goodness you remember!

Today we’re doing something a little different.  Instead of my usual breakfast of eggs and sausage or Keto almond flour pancakes, I wanted to try to make one of my favorite childhood treats – Keto Cinnamon Toast Crunch!

When I think back on some of the least healthy things I used to consume almost daily, breakfast cereal is at the top of my list.

Your typical breakfast cereal is loaded with processed sugar, refined carbohydrates, and a ton of ingredients I can’t even pronounce.  Sure, they may taste good, but at what cost?

My version uses simple ingredients but still tastes surprisingly like the real thing.

Without further ado, I present to you…

Growing up I ate all kinds of cereal.  Well, not all kinds…

None of the “healthy” whole grain cereals for me.  Nope!  I only loved sugary sweet varieties that were advertised during my Saturday morning cartoons.

Fruit Loops, Trix, Apple Jacks, Frosted Flakes, you get my drift.  But my all-time favorite (by far) was Cinnamon Toast Crunch.  I loved them in the morning and then after school (by the handful)!

Sure, I hadn’t eaten them in years.  But the keto diet does strange things to our minds. I found myself craving a low-carb version of Cinnamon Toast Crunch, so I set out to come up with a recipe.

And it sure didn’t disappoint!

Making Cinnamon Toast Crunch Keto Friendly

If you've been getting tired of eggs and bacon every day for breakfast, have we got a treat for you!

Sure, I knew I had to cut the grains and sugar out of our Keto Cinnamon Toast Crunch recipe, but I also wanted to increase the fat quite a bit too.

I love the marriage of butter and almond flour, so that’s what we started with.

And since we wanted our low carb breakfast cereal to be crispy but not dry, we add just a bit of xanthan gum to hold all of our ingredients together.

The Ultimate Low Carb Breakfast Cereal

As they begin to cool, the keto Cinnamon Toast Crunch squares become crispy...just like the real thing.

A delicious low carb breakfast cereal needs to be plenty sweet, so we again opted for two kinds of Swerve, just like we did in our Keto Chocolate Chip Butter Cookies recipe.

We use the Swerve Brown in the cereal and then use Swerve Granular for the topping.  This was the best combination of sugar substitutes we tried.  

Cinnamon is the star of the show here, and we wanted to use high-quality cinnamon in our keto cinnamon toast crunch copycat recipe.  

We opted for this Watkins cinnamon for its intense aroma and stronger flavor compared to traditional Ceylon cinnamon.  It did not disappoint.  Seriously, use this cinnamon!

NOTE: Sure, some of these ingredients are a bit more expensive, but I like to justify the increased expense based on the fact that I’m not eating out nearly as much as I did before keto.

For The Cereal

For The Cinnamon Sugar Topping


  • Whisk together almond flour, xanthan gum, cinnamon, baking soda, and salt in a medium bowl.  Set aside.
  • Beat softened butter for 2 minutes with an electric mixer until creamy.  Slowly stir in brown sugar swerve and continue mixing for 2 more minutes.  Add egg and beat until just incorporated.
  • Slowly begin adding butter mixture to the dry mixture (from step 1) and mix until well combined, about 30 seconds.
  • Transfer keto cinnamon toast dough to a large piece of plastic wrap.  Wrap tightly and chill for at least 2 hours.
  • Preheat oven to 375º F.
  • Place the chilled dough ball between two pieces of parchment paper and roll the dough to 1/4 inch thick using a rolling pin.
  • Using a sharp knife, slice the dough in a grid pattern to produce 1-inch squares. Poke each square with a fork or toothpick to keep it from puffing up while cooking.
  • Remove and discard top piece of parchment paper.  Transfer the bottom piece of parchment paper (with the cut dough on it) to a cookie sheet.  Bake for 8-12 minutes until golden brown.  Bake longer for extra crisp.
  • Remove from oven and brush with melted butter and sprinkle generously with the cinnamon sugar topping.
  • Allow to cool thoroughly and then break apart along cut lines.  Store in a Ziploc bag for up to a week.

      These are a nice crunchy sweet snack, thanks for the recipe! I used granulated monk sweetener instead and it turned out great. I also used a coconut chia flax seed mix on top to add a little fiber and texture.

  3. Can you use psyllium hush powder in place of xanthan gum and baking powder instead of baking soda?

  4. Just made a triple batch as a healthy snack for the grand kiddos and for my low carb lifestyle. It’s been a game changer since discovering this last year ❤️

    Just tried this recipe and loved it! I ended up keeping the dough in the frig overnight then rolling & cooking the next morning. One thing I need to watch is the time it cooks in the oven. My oven cooks fast. Only lost a few pieces to the dark side. Fun treat and not hard to make.

  6. Made this keto cinnamon toast crunch cereal few times. Perdy tasty. Made it tonight but I doubled some of the ingredients. Looks like turned out good 👍🏾😊
