These cinnamon cake bars taste just like coffee cake. They’re high in protein, low cal, low sugar with no oils or butter and perfect for a healthy snack.

Five years ago when this post was first published it was about 3 months before I first stepped foot into a CrossFit gym.
I was bouncing back and forth between HIIT workouts online, NROLFW and Jamie Eason’s LiveFit Trainer program desperately trying to find something that would help me build muscle.
Honestly, nothing really worked too well (sorry, but 15# dumbbells don’t really do much for muscle growth) and it wasn’t until July of that year when my CrossFit gym opened right down the road that progress finally started to happen.
If there’s one positive that came out of those few months of workout ambiguity though, it was this recipe for high protein cinnamon cake bars inspired by Jamie Eason’s recipe for cinnamon swirl bread I stumbled upon on her site one day.
Chocolate protein cake bars were another recipe from that era and I love those too!
This recipe also inspired by chocolate baked oats which is basically like cake but justified for breakfast!


Often times, people are hesitant to bake with protein powder saying the chalky taste can linger in the final product.
And while that can definitely be true, I’ll say this: it doesn’t happen as much with quality protein powder.
I didn’t always know this and I didn’t always care as much as I should about the sourcing of my whey protein.
These days, I use SFH Pure (their churro flavored whey protein is literally perfect for this recipe making the cinnamon flavor even more robust) or Vital Proteins almost exclusively as they’re both quality products whose standards live up to mine now.

While my workouts have changed quite a bit over the last 5 years since this was originally posted, my high protein post-workout snacking really hasn’t and these protein cinnamon cake bars are still a really great one I love to grab either right before or after my workouts.
They’re packed with protein, very low fat (like none really), gluten-free and a great source of healthy carbs to fuel you through whatever way you like to sweat.
Oh, and they seriously taste like coffee cake too.

Looks so tasty! I need to make it and sub out the greek yogurt for my homemade almond yogurt and use ground flax instead of eggs to make it vegan, but I’m sure it will be fabulous!
This cake looks so good! I love cinnamon in baked goods, and I’m always looking for new ways to add a little more protein to my diet, so this will be perfect!
uh yep, just as i suspected. looks amazing!!
i made these and my batter was EXTREMELY thick – i couldn’t even spread it! so i had to add some milk… was your batter also super thick?
Oh my gosh…i just realized I left out the 1 cup almond milk! I’m so sorry! Did they come out ok when you added the milk? Editing the recipe right now..
You had me at “high protein”
I’m just getting into ‘baking’ with protein powders too- more like using them in smoothies and no bake cookies, but still! It’s fun and surprisingly easy to use. and I LOVE those white plates a lot, very simple and beautiful.
I never bake with protein powder…heck it’s been years since I’ve even bought any or had any! These look so good and would have never guessed from the pics that there’s p.p. in them! Sometimes it seems to change the appearance/texture of food…but not these!
Neeeeed to make these!
i’m in love with almost any baked good, so when i have an option to make a delicious one that is healthy and protein packed, i’m sold! looks great!
Your cake looks delish! I wish I had vanilla protein, I only have chocolate right now. I understand about potion controlling things. I need to wrap my things up, freeze, whatever I can do to get it out of site out of mind! Have a great day!
