Now THIS is how I’d like to celebrate my 8th blogiversary!

Yes, ehem, I’ve been doing this whole “blog” thing for EIGHT SOLID YEARS.  My jaw has dropped.  My mind is blown.  I really don’t know how to wrap my head around this concept sometimes?  What started out as a hobby slowly grew and grew, that by year four I was like, “Wow, this has the potential to be my full-time gig!”  And by year six, I was able to quit my day job and officially become self-employed.  And for that, I am so incredibly grateful to each and every one of you.

Without you, this (bombass) recipe post wouldn’t be here.

Without you, this entire blog wouldn’t be here!

Healthy Birthday Cake Protein Bars with Cream Cheese Frosting and Rainbow Sprinkles

Before I get to the recipe, I wanted to say that these last eight years have been…  one helluva rollercoaster.  So many ups, so many downs.  There are times when the track is bumpy, and I swear there have been moments (read:  months) where it feels like the cart I’m in gets stuck upside down in a loop high off the ground, and the only thing keeping me together is a flimsy seatbelt.

To be honest, I’ve been struggling with blogging lately.  And by “lately” I mean well over a year.  I guess it’s a combination of things:

  • insomnia
  • hormone changes (thanks BC)
  • stress about work (I’ve hired a few people for various jobs, and ¾ of the people I hire are…  utterly terrible -_-)
  • stress about money (hoping to buy a house this year…  eek)
  • anxiety and depression (which is scary to me because I haven’t been depressed for nearly six years)

For those of you who may not know, I started this blog as a freshman in university — aka an eighteen-year-old who moved out of state (Connecticut to Arizona), to attend school when I didn’t want to be there in the first place (pressure from the parents), who was also dealing with anxiety and severe depression.  Certainly not the best formula.  The first semester was a disaster, as I changed my major four times, finally settling on Nutritional Sciences.  My full-time course load consisted of boring prerequisites, plus ALL the math and science (my two arch enemies).  All I did was study and drown myself in school.  My mental state was so bad, I would cry out of nowhere.  Didn’t matter where I was, in class, walking around campus, in my dorm.  I cried A LOT.  I visited home for the first time during winter break.  To give a little background, my family has never been close until recently, actually.  Talking and sharing feelings was never a thing.  But at one point I remember looking up how to admit myself into a hospital, and if I even could…  how much did it cost, did insurance cover it, is it put on your record somehow, would future employers know?  Even though it felt uncomfortable, I told my mom I was going to find a therapist.

During the Spring semester, I started catching up on the food blogs I used to visit.  I started cooking for the first time and got back into baking.  As a Nutritional Sciences student, I tried my best to bake healthier desserts with less sugar, less butter and oil, and more whole grains.  It was incredibly difficult and I baked off some pretty terrible tasting “things” but it was all worth it when I finally baked a perfect batch of Banana Bread.

After almost a full semester of baking (and procrasti-baking), I started this blog.  I didn’t know it at the time, but 4/20/2011 was a very special day 💕

For quite some time, my only source of joy was baking, posting recipes to the blog, and connecting with people all around the world, all thanks to the internet.

I so desperately want that passion back.  And I think I’ll be able to very soon  🙂  because I’m currently in the process of moving out of my apartment, which I’ve always hated because of its VERY tiny kitchen.  My temporary place has a bigger and better kitchen, but again, it’s temporary because I’m hoping to buy a place in a few months and can’t be stuck in a year-long lease.


Healthy Birthday Cake Protein Bars with Cream Cheese Frosting and Rainbow Sprinkles

These Birthday Cake Protein Bars are the perfect snack for when you’re craving something sweet, but don’t want the excess calories, sugar, and fat that come with a slice of cake.

Instead of white flour, we use gluten free oat flour.
Instead of butter and oil, we use natural almond butter.
Instead of white sugar and corn syrup, we use organic stevia extract.

Thanks to these easy ingredient substitutions, these protein bars are gluten free, low in sugar, and can easily be made vegan (just use vegan cream cheese)!

I mean, can life get any better??  Could our taste buds be happier??  We literally have UBER soft and fudgy protein bars topped off with a layer of rich and creamy frosting!!  And they don’t taste healthy in the slightest!!

Pardon my yelling.  I got excited.


Okay I’m done  😉

These Birthday Cake Protein Bars are easy to make, don’t require any baking, and take just 7 ingredients to whip up!

Watch me make a batch on camera:

Did you observe the fudginess at 2:44??  *drools*

Healthy Birthday Cake Protein Bars with Cream Cheese Frosting and Rainbow Sprinkles

Servings: 12 protein bars
Prep Time: 1 hour
Total Time: 1 hour
These no-bake Birthday Cake Protein Bars are fudgy, sweet, and taste like funfetti cake! Except these are made without the white flour, butter, and excess sugar. These are gluten free, vegan optional, and low sugar!


Protein Bars:

Cream Cheese Frosting:

  • 4 oz Neufchâtel Cream Cheese (or ⅓ Less Fat Cream Cheese; room temperature)
  • 2 tbs Unsweetened Vanilla Almond Milk
  • ½ tsp Vanilla Crème-Flavored Liquid Stevia Extract
  • ¼ cup Natural Rainbow Sprinkles


For the Protein Bars:

  • Line an 8x8” brownie pan with parchment paper. Set aside.
  • In an electric stand mixer bowl fitted with a beater attachment, add all of the ingredients. Mix on low speed until everything is fully incorporated.
  • Scrape down the sides of the bowl. Mix on medium speed for one last mix. Mixture should be thick and fudgy, like cookie dough.
  • Scoop the mixture into the brownie pan and flatten it out.

For the Cream Cheese Frosting:

  • In a medium-sized mixing bowl, whisk together the cream cheese, almond milk and stevia extract. Scoop mixture over the protein bar base and spread to the edges of the pan (I used an offset spatula). Place in the freezer uncovered for 1 hour.
  • Lift the mixture out of the pan. Slice into 12 bars.
  • Scatter the sprinkles on top. To store, simply place a sheet of parchment paper on top of a cake pedestal, arrange the protein bars on top, and cover with a cake dome (keeps for 1 week in the fridge or a few months in the freezer).

Recipe Notes

Do not use whey protein powder...  you'll get a gooey, sticky mess!
If you'd like to make an ingredient substitution, you'll have to test that in the kitchen on your own.  I tested the recipe above and feel it's perfect as is  😉

  1. I was looking for a cake protein bar for the whole family and I stumbled on this article. I read and followed the instructions carefully and I made it deliciously! Every member of my family is so happy! Thanks for this!5 stars

  2. I’m curious if you noticed a change in taste of the Sunwarrior vanilla protein powder in the past few months. I clicked on your link above and the reviews for their newest product has terrible reviews. 1.5 stars out of 5. People that had been faithful customers for years are now hating the new recipe/formula/taste and wondered what your thoughts were?

    • Oh no! I am at the last little bit of my SunWarrior container and have to buy a new one soon. I really hope they haven’t changed their formula… ugh. What a bummer.
      However I WILL say I’ve never really liked their brown rice protein powder in smoothies. It’s gritty and flavorless. Protein bars are the only way I like to eat their product because when it’s mixed with nut butter and another flour it’s fudgy and delicious!

  3. Happy Birthday, Jess. I’ve been a follower for eight years and have the Protein Bars book and the Naughty and Nice book. Your blog is one of the first nutritional science experiments I’ve enjoyed and followed the recipes. You alone got me off sugar and white flour. What a genius you are to create from these unknown products and do trials for us! I’m a healthier fan!

  4. P.S. i’d have never known you spent a day in depression. The patterns are very familiar to me since college. I’m glad you’re using Birth control, because I got pregnant one lonely day.
    Everyone needs attention and relationships are the one thing we are here to learn in this life.
    Each person has contributions and you just search until you click, and leave when you need to be alone again. Isolation is not helpful without supportive friends or a group who knows you. I thank God for you. Be well.

    Love your blog! Keep posting please is always great to find healthy a d nonguilty recipes! Throw away the sadness and keep showing the best to th world.5 stars

  6. Happy belated anniversary to your blog! Definitely celebrate with all the birthday cake flavored protein bars that you wish. I I’ve always wanted to try making my own protein bars–this is a must-make then! Will this recipe work with vegan protein powder?

  7. I was looking for a healthy diy protein bar recipes because the store bought ones can be too expensive and has unnecessary ingredients but I couldn’t find one that actually tasted good but this is definitely a win for me !! 😀 so glad I found your blog ❤️5 stars

    • OMG I was in the same exact boat when I started writing this cookbook! There were seriously only junk-food bars on the market back then. Things have definitely gotten better in terms of health and ingredients, but the cost per bar is SO high. I’ve seen $5 bars and that blows my mind.
      Super glad ya found my blog too!! 🙂

  8. I think they taste like play doh, and not in a good way 🙁 so sorry! It was expensive to make them so I am bummed.

  9. Hi, Jess. I love all your recipes. I would really like to make the dough without any almond milk or any watery liquid. Do you think if i replace the 1cup of almond milk with a mixture of date syrup and brown rice syrup, that would work? Or is there anything else i can add in? I dont want anything with water in it that can make it go off quick..5 stars
