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 in the US. 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, such as allulose or Bocha Sweet.
Baking powder, cinnamon and vanilla extract - no explanation needed!
See the recipe card for full information on ingredients and quantities.
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 and make adjustments if necessary!
This section contains step by step instructions and photos that show how to make this recipe. See the recipe card for full information on ingredients and quantities.
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. Whisk until smooth. Option to also add a pinch of salt.
Step 3: Stir together the cinnamon sugar for the filling.
Step 4: 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.
Step 5: 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 cake.
Step 6: 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.
Step 7: Pound the pan gently on the counter again and then bake in the oven until golden and until a skewer inserted comes out clean.
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.
Below are my top tips to make this bread a success.
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.
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.
Yes. A handful of crushed pecans or walnuts adds a nice crunch to the cinnamon swirl.
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.
Store your 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. You can also slice and freeze it for up to 6 months.
I love to gently reheat a slice in the microwave and serve it spread with butter. A cup of almond milk matcha latte is the perfect match.

Note: The servings slider only changes the first amount in each line and not any subsequent amounts. Please make your own calculations where necessary.
- 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
- ¼ cup granulated sweetener 50g
- 1 tablespoon cinnamon
- Preheat the oven to 180 Celsius / 350 Fahrenheit and line a loaf pan with parchment paper. I used a full size silicone loaf pan.
- 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 pea protein flour be substituted for whey protein?
I have not tried it but I think that would work, yes.
