Ingredients needed
This recipe calls for simple pantry staple ingredients. Here is what you’ll need:
- Oat flour. Skip the expensive store-bought varieties and make your own.
- Coconut flour. Substitute it for almond flour if you like.
- Protein powder. I like using a vanilla-flavored protein powder but unflavored also works.
- Cinnamon. To flavor the cinnamon bars.
- Sweeteners. You will need some granulated sweetener as well as some brown rice syrup.
- Almond butter. Any other nut butter will work too.
- Vanilla extract. To make the flavor of cinnamon bars richer.
- Milk. I used unsweetened almond milk but any milk works.
For the topping:
- Cinnamon
- Granulated sweetener of choice. White sugar, brown sugar, or even a sugar substitute.
How to make cinnamon protein bars
Only a few minutes of mixing and these cinnamon protein bars are ready to be enjoyed. Here’s how you make them.
Step 1 – Combine the dry ingredients
Add flour, protein powder, granulated sweetener, and cinnamon to a large bowl and mix well to combine.
Step 2 – Melt the nut butter and combine all ingredients
Add the nut butter and liquid sweetener to a microwave-safe bowl and microwave until fully melted. Add the vanilla extract and pour the melted nut mixture over the dry ingredients. Mix well. At this point, the mixture should be crumbly. Add the milk one spoonful at a time and mix until a firm mixture is formed.
Step 3 – Press the mixture into the pan and chill
Press the mixture into a baking dish lined with parchment paper. Rub on the cinnamon topping and refrigerate for 30 minutes or until fully set. Once set, cut into slices and enjoy.

Tips to make the best recipe
- Depending on the type of flour you use, you may need to add more milk to achieve the right consistency for the bars.
- Coat the knife with cooking spray to be able to slice the bars without sticking. Wipe the knife clean after each slice.
- If you want to increase the amount of protein per bar, drizzle them with a protein drizzle. For the protein drizzle, simply mix equal parts of protein powder and milk.
Storage instructions
To store: Store these cinnamon protein bars in an airtight container in the fridge for up to 7 days. You may want to wrap the bars with parchment paper to prevent them from sticking to each other.
To freeze: You can also freeze cinnamon protein bars for 2 to 3 months. When you are ready to eat them, remove the bars from the freezer and allow them to thaw and soften.

Hi Arman. I made these today and they’re absolutely excellent. I’ll be eating them to lose weight and while maintaining. They’re just that good. Thank you.
How long do these last refrigerated/non refrigerated?
Hey Ryan! I keep them refrigerated for up to 5 days (they only last that long, I eat them regularly), in room temperature, I consume within a day 🙂
Can’t wait to try these! I absolutely love your blog!!
Thanks so much, Hilary- Glad to have you here! 🙂
These are spectacular! Just what I’ve been trying to pull together but haven’t gotten the ratios of ingredients just right. Chewy, nicely sweet, full of protein. Boo Yah you hit a homefun Arman!
😀 Micki! This comment absolutely made my day- Have a fantastic Monday! 🙂
Mine came out kind of sticky. Not stick to my fingers sticky but if I cut one out and held it upright it would slowly fall over and it did stick to the paper towel I was holding it with. And mine didn’t look anything like the picture lol
Hi Julie! I’m so sorry yours came out like that- Did you by any chance use whey? That often is the culprit for the sticky factor!
What is “Cinnamon Bun Topping”?
Hi there! It’s listed in the ingredients, the cinnamon mixed with the granulated sweetener 🙂 enjoy!
I can’t wait to make this recipe! Is there a way to get calorie, fat, protein and carb counts per serving?
Hi Amy! Definitely- if you add the ingredients into a calorie calculator, it will provide it for you 🙂 Enjoy!
These did not work well for me. I used 1cup almond flour (because I have a LOT of it), 1 cup oat flour, 1/2 cup coconut flour. Otherwise did everything as directed. They simply did not hold together. Had to eat them with a spoon. 🙁 Protein powder gave them icky flavor too.
Hi Nanci- As per the instructions, it indicates to use 2 cups oat flour (or 1 cup of coconut flour) and the extra 1/2 cup coconut flour. You added almond flour instead of the oat flour which would have changed the texture dramatically- This is why it didn’t form 🙂 If you can, continue adding some coconut flour then add more liquid. As for the protein taste, that is dependant on what protein powder you use. The 3 I trialled all tasted great.
so is it one and a half cups of coconut flour total? thank you.
Hi Meg! that is correct- Because coconut flour is like a sponge, replacing 2 cups of oat flour for 1 cup of coconut flour is needed. The second line of coconut flour needs to be added too 🙂 Cheers!
Food comes first, because without food, I’d have no friends. Come feed me? But not with norbu — it kind of sounds like seaweed to me. Cinnamon me up instead.
Lol! Me and Alexis went through it like water!
