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.

    1. 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 🙂

  2. 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!

  3. 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

    1. 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!

    1. Hi there! It’s listed in the ingredients, the cinnamon mixed with the granulated sweetener 🙂 enjoy!

  4. 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.

    1. 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.

        1. 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!

  5. 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.

  6. I can be pretty hangry so for the sake of my friends I have to choose food sometimes. And so by choosing food I am basically an outstanding friend! Makes sense?

    I NEED to make these soon. Cinnamon <3 <3 <3

    P.S. I like the new layout elements

  7. I’ve been breakfast and lunch prepping for the work week. Looks like I’ve got to make these for snacks this week!! I think I have all the ingreds..

  8. Glad I found your site and these these bars sound awesome. I am slowly playing with no bake paleo recipes so will give these a try.

  9. It depends on my mood whether friends or food come first. If I’m not hungry, friends. If I’m hungry, it’s 50/50. If I’m hangry, it’s food 100%.
    Saigon cinnamon ♥︎ ♥︎ ♥︎ God bless Costco.

  10. Ooh, that’s a toughie….it honestly depends on my mood! I was going to see a horror with my friends, but I really couldn’t pass on Indian food XD no in all seriousness, I’d always support them if they need it! You need both to be happy! I definitely have to try making these cinnamon bun protein bars ASAP! Same with your cookies n’ creme bars!

  11. I love these bars — no bake and quick to put together! That picture cracked me up! 🙂 And, you are a sweet friend! To answer your question; I always pack a protein bar in my carry-on luggage.

  12. I need to try this magical sugar. I’m trying to use up this protein powder that I got to try but it’s so sickeningly sweet w Stevia but not even a good sweet like when you eat 23543456 chocolate chip cookies.

  13. food comes first! for sure lol. My travel foods always involve packets of oatmeal, jars of peanut butter and peanut butter sandwiches. None of this is shocking, I know 😉

    1. Hahahaha. I love it. I was at a hotel a few weeks ago and saw oatmeal, apples and packaged peanut butter. I was like…MEREDITH!

    2. Anyone subbed raw honey as a sweetener? We have bees and would prefer use to their honey as our sweetener choice. Would love your thoughts!

  14. Depends on the food and the friend. If it was cats or food, definitely food. My cat would choose the same. We have an understanding. My travel food is a donut. No trip is complete without a stop at Dunkin Donuts

  15. Never tried Norbu before. I actually have never even heard of monk fruit sweetener until I saw it on your blog. I bought a stevia plant last year and thought I was going to do all kinds of great things with it, but I didn’t. For months, it sad out back with the rest of my herbs, growing larger. Occasionally I’d take off a leaf and lick it, think “mmm, it’s sweet,” then ignore it again. Finally, it died.
    Anyway, hope you liked that story. Have a great weekend.

  16. I’ve heard a lot of people say that about stevia, but I’ve never really noticed it. I guess I don’t bake with it too much though. I’ve never heard of Norbu! Do regular stores carry it now?

  17. The only problem with these is that they won’t make the entire house smell like cinnamon… send a candle to all who make them.
