This keto cinnamon bread is so fluffy! It has a sweet cinnamon swirl and you can prep it in just 10 minutes. Even better, this easy breakfast treat is only 2.2g net carbs per slice.

I want to tell you how the idea for this low carb cinnamon bread came about. I adore my keto cinnamon rolls, which are wonderfully gooey. But you know, they do take a little time. Also, I wanted the same flavors without making fathead dough.
That's when I decided to create a keto sweet bread bread with a lush cinnamon swirl. Easier, and quicker, and the taste is just as good!
My entire family enjoyed the moist and fluffy vanilla-flavored crumb of this bread. Essentially, it tastes like a cinnamon roll, just not quite as sweet.
You'd never guess that it is gluten free, grain free, sugar free and keto!
Also try this coconut flour banana bread or my keto blueberry bread.

Ingredients
Here are the ingredients you need to make a keto cinnamon bread:
Almond flour and coconut flour - I'm using ground almonds. This is equivalent to regular almond flour. If you use super-fine almond flour, reduce the amount to 2 cups or 200 grams.
Whey Protein Powder - I'm using unflavoured whey protein isolate. It's low in carbs and helps give a very fine crumb and great texture. Also, it adds a nice protein boost.
Eggs - Use large, room temperature eggs. Beat them well to get as much air into them as possible for a lighter crumb.
Butter - The butter should be melted and then cooled.
Almond milk - I love Plenish almond milk, which is unsweetened. Using milk over cream creates a lighter crumb structure.
Sweetener - I used a "brown sugar" erythritol monk fruit sweetener blend because it goes well with the cinnamon. However, any white granulated sugar substitute works as well, such as allulose or Bocha Sweet.
Baking powder, cinnamon and vanilla extract - no explanation needed!

Method

First, I preheat the oven and line a rectangular loaf pan with parchment paper. Then it's time to make the batter. I used a mixing bowl and an electric mixer, but you can also use a food processor.

STEP 1
Beat the eggs in a large mixing bowl until frothy and doubled in size.

STEP 2
Add the wet ingredients and after that the dry ingredients. Blend until smooth.
Option to also add a pinch of salt.

STEP 3
Stir together the cinnamon "sugar" for the filling in a little bowl.
Fill half the batter into the loaf pan and sprinkle the cinnamon mixture onto the top. Then add the rest of the batter over the cinnamon layer.
Bounce the loaf pan onto the kitchen counter a few times so the batter settles evenly. Then spread the remainder of the cinnamon mix on top of the bread.

STEP 4
Stick a knife inside the batter and swirl it up and down lengthways and then from side to side, moving from one end of the pan to the other. This creates the marble effect.
Pound the pan gently on the counter again. This removes any large air bubbles.
Then, bake the bread in the oven until golden and a skewer inserted comes out clean.
Katrin's Top Tips
Measure with kitchen scales. Measuring in grams is much more exact than using cups. Especially coconut flour expands a lot and if you pack your cup you may end up with a lot more than you intended. If you don't have scales, sift the coconut flour into the cup and level it.
Check the batter. The consistency should be thick but not as firm as cookie batter. Check the images for reference. Loosen dry batter with an extra tablespoon of almond milk.
Don't let it over-brown. Check the cinnamon swirl bread during baking. If it is already browned sufficiently, loosely place a piece of aluminium foil over the top to stop it from burning.

Substitutions
- No coconut flour: Replace the coconut flour with 3x the amount of almond flour.
- No whey protein powder: Replace the whey with ¼ cup / 25g more almond flour.
- Dairy-free. Replace the butter with coconut oil and use egg white protein instead of the whey.
With all substitutions, check that the batter consistency mirrors mine by looking at the video and the images. Make adjustments if necessary!
Toppings and Add-Ins
Nuts - Crushed nuts add a lovely crunch. You can stir the nuts into the cinnamon and sweetener mixture. Walnuts and pecans taste great in this bread.
Pumpkin Spice Bread - Use pumpkin pie spice instead of the cinnamon. Or, add ginger, cardamom, nutmeg and a pinch of allspice to the swirl mixture.
Keto Cinnamon Roll Bread - To make this bread taste even more like a cinnamon roll, add a cream cheese frosting! Use the recipe from my keto pumpkin bars.
Make it fruity - Add finely(!!) chopped apple or sugar free dried cranberries. To keep it keto, don't use more than 2 small apples in total.
Cinnamon Topping - For cinnmon lovers! Sprinkle more cinnamon + sweetener mix over the bread or add the cinnamon streusel topping from my keto apple cake.
Recipe FAQs
Regular cinnamon bread is made with wheat and sugar. It is not keto friendly. By swapping these out for low carb flours and a zero carb sugar substitute, my keto cinnamon bread contains just 2.2g net carbs per slice.
Of course. Mix powdered sweetener and water or cream until smooth, then drizzle onto the bread. Or make the coconut butter drizzle from my Keto Lemon Pound Cake.
I think it tastes best warm! I gently reheat a slice in the microwave and serve it spread with butter. You can also toast it and spread it with cream cheese. A cup of almond milk matcha latte is the perfect match.
Storage
Refrigerator: Store keto cinnamon bread just like you would any other bread - in an airtight container at room temperature for about 4 days or in the fridge for up to 6 days.
Freezer: You can slice and freeze it for up to 6 months. Arrange the slices on a baking tray without them touching, then freeze until solid. After that, store them in a freezer bag. This way, they don't stick together.
Defrosting: I thaw single slices as needed. You can reheat the slices in a toaster or gently warm them in the microwave (about 10 seconds).

Keto Cinnamon Bread
Equipment
- 1 9x5 loaf pan
Video
Ingredients
- 5 eggs large
- ½ cup granulated sweetener 100g
- ½ cup butter 114g, melted
- ⅓ cup almond milk 80 ml, unsweetened
- 2 teaspoon vanilla extract
- 2 ¼ cup almond flour 225g, ***see notes
- ¼ cup coconut flour 30g
- ⅓ cup whey protein powder 33g, unflavoured
- 2 teaspoon baking powder
Cinnamon Swirl
- ¼ cup granulated sweetener 50g
- 1 tablespoon cinnamon
Instructions
- Preheat the oven to 180 Celsius / 350 Fahrenheit and line a loaf pan with parchment paper. I used a full size silicone loaf pan (9x5 inch).
- Beat the eggs until frothy and pale. They should double in size. This takes about 2 minutes. Add the granulated sweetener (I used brown Lakanto) and continue beating for a further 1 minute.
- Next, add the melted butter, vanilla extract and almond milk and mix until well combined.
- In a separate bowl, mix the dry ingredients - almond flour, coconut flour, unflavoured whey protein powder and baking powder. Add the dry to the wet ingredients and blend until combined.
- Now stir together the granulated sweetener and cinnamon for the filling.
- Fill half the batter into the loaf pan and scatter the cinnamon mix onto the top. Then add the rest of the batter over the cinnamon layer. Gently bounce the loaf pan onto the counter a few times so the batter settles evenly. Then spread the remainder of the cinnamon mix on top of the cake.
- Stick a knife inside the batter and swirl it up and down lengthways and then from side to side, creating the marble effect. Pound the pan gently on the counter again and then bake for 50-55 minutes or until a skewer inserted comes out clean.
- Check the bread after 40 minutes. If it is already browned sufficiently, loosely place a piece of aluminium foil over the top to stop it from burning.
- Let cool completely before cutting.

Can u use vanilla flavored whey protein
Katrin Nürnberger
Yes, of course. As these are sweetened most of the time, reduce the sweetener in the recipe.
Janet
Can you make this without the Whey protein? I'm dairy free and don't fancy using anything milk derived.
Katrin Nürnberger
You could use more almond flour.
Nicky
Hi! I absolutely LOVED the sugar free keto pumpkin bread and I definitely want to try this.
For the granulated sweetener, does it matter if its white or brown? I have both Truvia granulated (1:1 sugar substitute), but the brown does have a hint of molasses...do you think this would taste okay or should I stick with the white? I am new to all this, diagnosed diabetic a bit back so trying to find new recipes to love!
Thank you for your time!!
Katrin Nürnberger
I think it would taste good with either sweetener.
Kim
Made this recipe today, but chose to make muffins instead. 350° for 21 min. Turned out great. Next time I will start checking at 18 min. I think the recommended drizzle would be a perfect addition here.
Adriana Gutierrez
These might make nice muffins too!
Katrin Nürnberger
Yes, you can use the same batter for muffins. Takes about 25 minutes in the oven.

I find recipes made with almond flower to be bitter and I don't like the density of the bread. Can I use just coconut flour or another flour for a lighter product?
Katrin Nürnberger
The only reason for an almond flour product to be bitter is when the almond flour is off. I always recommend storing open almond flour in the fridge so it does not oxidise and lasts longer.
You could try to replace the almond with one third the amount in coconut flour. Note that I have not tried this myself yet, but it is the amount I would go for.
Jane
Can I substitute sunflower seed flour for the almond flour? And if so, any suggestion for the almond milk?
Katrin Nürnberger
I find that a 50/50 blend of sesame seed and sunflower seed flour is a good nut free 1:1 alternative to almond flour. You can use any milk or milk alternative of your preference. I like almond milk because it is low in carbs. But in terms of texture, any milk will work.
Juanita
Could I use flaxseed as a substitute for the whey protein powder. Thanks
Katrin Nürnberger
You could try that. I think the amount may be different, perhaps a little less. You'll need to check the dough consistency as you mix. Obviously, it'll make the bread taste more "rustic" as well.
Juanita
Hi,
I'd love to try this recipe but is the temp 180 fan? Thanks
Katrin Nürnberger
It's 180C in a regular oven. Reduce it to 160C for a fan oven.
Linda Bartlett
Will this recipe work with egg substitute? Thank you
Katrin Nürnberger
I have never tried that. I think it would change the texture. It's the eggs that make the bread fluffy.
Kathleen Schilli
What brand of unflavored whey protein isolate do you use or recommend?
Katrin Nürnberger
I always used to buy Pulsin, but it seems to be out of stock everywhere. There are other brands on Amazon.
