Ingredients for Birthday Cake Protein Bars Recipe:
These birthday cake protein bars are made with simple healthy ingredients, have no sugar or heavy cream, making them the perfect gluten free, dairy free and sugar free homemade protein bar!
- Oat Flour – You can make your own by blending rolled oats in a high speed blender
- Unflavored Protein Powder to replace some of the flour (and carbs) in the recipe for a slightly lower carb high protein. I recommend the Multi-purpose mix protein powder from Quest Nutrition.
- Vanilla Protein Powder – key for the high protein birthday cake bars.
I used Quest Vanilla protein powder here.
- Coconut Flour
- Sugar free Maple Syrup for low calorie protein bar with no sugar!
I use the sugar free monk fruit maple syrup from Lakanto (code HAYLSKITCHEN gets you a discount) - Almond Milk
The Protein Frosting layers
These raw cake batter protein bars use a high protein and sugar free icing made with Greek yogurt and protein powder.
- Vanilla Protein Powder for high protein icing.
I recommend the same here too: Protein World Slender Blend, ProteinWorld Whey, or Quest. - Non fat Greek Yogurt
- A bit of Coconut Flour
And for the Chocolate Coating:
- White Chocolate Chips or Chopped Chocolate. I would recommend Lily’s to keep it sugar free.
- Coconut Oil so the chocolate is easier to melt and more smooth when you drizzle.
Tips for Protein Powder Birthday Cake Bars
These protein powder birthday cake bars with all the sprinkles and funfetti are really easy to make, but here’s some tips to get it right.
- Use whey-caesin protein powder since it works well with the ratio of ingredients here. If you use a whey protein powder, you might want to adjust the amount of milk to make it less.
- Mix the dough well to form a smooth mixture, but don’t over-mix since the protein powder might make the texture tough.
- Let the healthy birthday cake bar layers chill before adding the chocolate and slicing, or they will be too soft.
To store Homemade Cake Batter Protein Bars
High protein cake batter bars use Greek yogurt for the frosting layer and can only be kept a few hours on the countertop.
Store homemade funfetti protein bars in an airtight container in the fridge or freezer so they stay fresh and last longer. They keep in the fridge for up to a 1 week.
To freeze, place cake batter protein powder bars in airtight sealed container, or individually wrapped in plastic wrap and placed in zipper bag; They should keep for 2 or 3 months. Be sure to let them thaw on the counter before eating!
Alternatives for Healthy Birthday Cake Bars Recipe!
I made this healthy, sugar free and gluten free and low calorie birthday cake bar recipe with this particular ingredient list, but here’s some options to choose from.
- Oat Flour: Almond flour
- Unflavored protein powder: Unflavored Collagen, or even Almond flour or Oat flour
- Sugar free Maple Syrup: Regular maple syrup or Honey, but they won’t be Vegan or a no sugar recipe anymore.
- Coconut flour: Try using about 3 tablespoon of Almond Flour
Options for the Protein Icing:
- Greek Yogurt: Coconut Yogurt

Vegan Funfetti Protein Bars recipe:
Since there’s no milk in this funfetti protein bar recipe, they can easily be made Vegan with the right ingredients.

You also want to make sure you use dairy free chocolate chips to make these homemade healthy protein bars.

Oh yeah! I made them … just as written! Delicious and OH SO GOOD!! I have been buying a name brand bar everyday after work at a convenience store on my way home—- $3.49. Not any more! Thank you
Haylee Jane Monteiro says
Oh my gosh Doris! You are more than welcome!
These homemade birthday cake protein bars are definitely my preference over the store bought stuff. I’m so glad you loved them!
Can’t wait to see what protein bar you make next!
Abby says
This recipe is awesome, the only problem I had was I had to add a tbsp of cashew milk and a little more yogurt to the frosting but that was just bc my yogurt was pretty thick. Other than that this was like the easiest recipe to follow and all the ingredients were easy to use as well. I didn’t have unflavored protein powder so instead I used a tbsp of ground flax seed and 2 tbsp of powdered almond butter and it worked like a charm. Thanks for sharing this!!! I was licking the frosting off the spoon as I was making it, it was so good, almost better than normal buttercream and it didn’t even need any sugar! Love this, if anyone is considering making these please do!!!
Abby says
I forgot to mention it’s a funny coincidence bc I have the exact same vanilla quest protein powder and the same Lilys unicorn swirl chocolate chips, I love Lilys and I 100% agree quest is the BEST protein for baking and tastes delicious
Haylee Jane Monteiro says
Haha, I totally agree with you!
Quest really is my #1!
Haylee Jane Monteiro says
Omigosh Abby!
This really made my day! These birthday cake protein bars are definitely one of my favorites and I’m so so happy you loved them too!
Different brands of yogurt can differ in thickness so that might have been it.
I may or may not have been licking that frosting off the spatula too haha.
Ginger says
These are delicious and will be making again!
