Oh Yeah! ONE Bar Chocolate Birthday Cake: Trans Fats Added?!

OhYeah! ONE Bar Chocolate Birthday Cake

The newest ONE Bar flavor is out from OhYeah! and it’s the childhood favorite, Chocolate Birthday Cake.

When you reach the upper echelon of excellence in a particular industry, you have two options:

  1. You can enjoy your success and rest on your laurels, or
  2. You can continue to improve, innovate, and dominate the competition

OhYeah! has clearly taken option #2. Ever since their release, the much heralded Oh Yeah ONE bars have been nipping at Quest’s one-time monopoly on the protein bar market. Rather than just be content with mild success, OhYeah has continually developed new flavors and improved the textures of their bars.

Speaking of new flavors, the newest ONE bar flavor to hit the market is Chocolate Birthday Cake. We know, they already have a birthday cake flavor, but this one is chocolate!

Chocolate Birthday Cake ONE Bar

OhYeah! ONE Bar Chocolate Birthday Cake Closeup

Chocolate Birthday Cake lives up to its billing with a light layer of frosting enveloping a moist, tender cake inside. Unfortunately, those sprinkles get everywhere, and they’re providing the trans fats too…

Whether it was your own birthday, or someone else’s, chances are you’ve had a delicious piece of chocolate birthday cake at one point in your life. So, you probably don’t need us to describe just how delicious a properly baked and frosted cake can be. But, how does the iconic party fare translate into protein bar form? Let’s find out…

The biggest problem with Quest Bars is that they’re no longer soft, spongy, or “moist” like birthday cake is. ONE Bars, on the other hand, are.

Unwrapping the bar from its restrictive wrapper, you’re greeted by a cascade of sprinkles adorning the top of the protein bar, but beware according to consumer feedback there’s always a few renegade sprinkles that detach from the bar and litter your counter. Below the top sprinkles, the bar is enveloped in a cohesive layer of mock chocolate frosting, not too thick and not too thin, just like a perfectly made chocolate birthday cake should be.

Now, you get to the real goods of the new flavor, the actual cake part of chocolate birthday cake. The closest way to describe the bar is pure Devil’s food cake. The inside is moist and soft a rich cocoa flavor and a subtle hint of vanilla (which is always used when making chocolate cakes. Community feedback has stated that it’s a deeper, darker chocolate flavor that what is employed by other brands on the market.

Chocolate birthday cake has a soft chew and almost melts in your mouth due to its tenderness, it really does emulate the taste and texture of a true piece of chocolate cake. Another perk is that the frosting layer isn’t overly sweet as can sometimes be the case with store bought chocolate frosting. And what better way to finish, than with some sprinkles on top, they don’t contribute a ton of flavor, but they do add some textural contrast, and what’s a birthday cake without sprinkles?!

Chocolate Birthday Cake Macros

OhYeah! ONE Bar Chocolate Birthday Cake Ingredients

Chocolate Birthday Cake has it’s own unique set of macros, but beware there are trace amounts of TRANS FATS in the bars due to the inclusion of partially hydrogenated vegetable oil. Probably not the end of the world, but do we really want that?

As we always do, we’re going to stack up Chocolate Birthday Cake’s macros against PricePlow’s current front-runner, Lemon Cake. Keeping with tradition, it should come as no surprise that Chocolate Birthday Cake is just a little bit different from the rest of the pack:

  • Calories: 210 (60 from fat) vs. 220 (60 from fat) for Lemon Cake
  • Protein: 22g vs. 22g for Lemon Cake
  • Carbs: 25g (10g Fiber) vs. 23g (10g Fiber) for Lemon Cake
  • Fat: 7g (4g saturated) vs. 7g (5g saturated) for Lemon Cake

Hold the Phone… Hydrogenated Oils?!

While we may laud OhYeah! For their continued innovation and excellence in the area of tastes and textures, we wouldn’t be doing our job if we didn’t call them out for including a rather nefarious ingredient: Partially Hydrogenated Vegetable Oil (a.k.a. Trans-fat).

We haven’t seen this ingredient pop up in any other flavors with the exception of original Birthday Cake flavor. So, that leads us to think Oh Yeah! Is including trans fat to either simulate the frosting texture or it’s in the sprinkles.

Regardless, in this day and age, there’s really no excuse for including this ingredient in any food – especially one that’s packaged as a health food!!

Trans fats are a type of man-made fat that the food industry loves to include in all sorts of pre-packed cookies, cakes, and chips, but our body doesn’t really love it all that much, especially our cardiovascular systems. Numerous studies have linked trans fatty acid consumption with cardiovascular-related diseases such as myocardial infarction and heart disease.[1,2]

To further drive home the point, the FDA has removed the generally recognized as safe (GRAS) from trans fats due to the volume of research highlighting the potential hazards of these fake fats.[3]

Put simply, because of these dangers it’s standard practice to avoid any product that says “hydrogenated” on it. However, it’s really just a trace amount of them, so maybe it’s not THAT bad:

It’s from those annoying sprinkles

Oh Yeah! ONE Bar Chocolate Birthday Cake New Flavor

There’s no doubt the newest ONE Bar will be absolutely delicious, but can we please put the freaking sprinkles inside and/or remove the trans fats from them?!

Per the label, the hydrogenated oil comes from the sprinkles – which are annoying anyway! The sprinkles get all over the place when eating the admittedly delicious regular Birthday Cake ONE Bars, making it nearly impossible to cleanly eat somewhere like in the car (unless you want to end up sitting on crushed sprinkles that end up embedded into your car seat). So we’re guessing this will be the same – annoying sprinkles adding unnecessary hydrogenated oil. At least we can guess that it’s probably a trivial dose.

We’d rather just have neither the sprinkles nor the trans fats and not have to worry about it.

So while ONE Bars are some of the best on the market when it comes to flavor and texture, but when there are a number of other competitors out there not using this fat, we really don’t see the upside outweighing the downside on this one.

Ok, rant over.


OhYeah! continues to light up the protein bar market with new and interesting flavors. There aren’t a lot of other chocolate birthday cake flavors on the market, and from what we’ve heard, they either don’t have the taste or don’t have the texture – all of the ONE Bars we’ve tried have had both, though!

This new flavor from Oh Yeah! Seems to be a surefire winner, if you’re ok consuming very small amounts of trans fats. If not, stick to some of the other ONE bar flavors.
