Homemade birthday cake is simple but so good!
This was my husband's birthday cake. He wanted red velvet, half with cream cheese frosting and the other with German chocolate frosting. It was moist and chocolatety, velvety soft, and oh so good. Just the right amount of sweetness. Homemade by the way!

A sweet, cake-inspired protein bar with a soft tex
ONE Brands Birthday Cake bar has a sweet, dessert-like flavor that really does remind you of birthday cake. The texture is soft and slightly chewy, with little crunchy bits that add a nice contrast. It’s definitely on the sweeter side for a protein bar, but it makes it feel more like a treat than a typical snack. The aftertaste is pretty pleasant compared to many protein bars, and it’s a good option when you’re craving something sweet but still want some protein.

Convenient go to snack
[This review was collected as part of a promotion.] Cons: Aroma is delicious like a birthday cake. Bar is very filling and makes a great quick snack. Pros: Consistency is chewy and I personally do not like chewy bars or cookies. The chewy consistency makes it stick on the back of your teeth giving you a not so pleasant mouthfeel.

Not too bad...
I bought this yesterday and tried it today. Personally, I think it tastes like the Florida at the dentist office. With a little birthday cake flavor.

Protein Bars
[This review was collected as part of a promotion.] The protein bar has a very sweet taste. I eat protein bars every day, and I didn't really like this flavor. The texture is average, a little uneven. It leaves an unpleasant aftertaste for me. I like a high amount of protein.

It was OK
[This review was collected as part of a promotion.] I found this to be pretty similar to a lot of protein bars and what not it comes with cute packaging. Looks taste and smells pretty good for protein bar. I definitely pick it up again.

Great protein bar
[This review was collected as part of a promotion.] The ONE Bars Birthday Cake protein bar is actually really good. It has a sweet, cake-like flavor without being too heavy, and the texture is soft enough to eat without struggling. It’s filling, has a good amount of protein, and makes a nice quick snack when I need something easy. Definitely one of the better dessert-style protein bars I’ve tried.

It’s ok but not a staple for me
[This review was collected as part of a promotion.] Okay, so I finally tried the ONE Birthday Cake protein bar, and lemme tell you — it’s giving gym girl dessert vibes. The good stuff: • 20g of protein and only 1g of sugar • Actually tastes like birthday cake — vanilla frosting + sprinkles kinda sweetness • Feels like a treat but keeps you on track • Gluten-free win The not-so-cute stuff: • Uses sugar alcohols, so if you’ve got a sensitive stomach… proceed with caution • Texture’s a bit chewy — it’s still a protein bar, not a real slice of cake • On the pricier side for a quick snack My rating: 4/5 It’s sweet, satisfying, and low-key feels like a reward after a long day. Not perfect, but definitely one of the better-tasting protein bars out there. #ONEbar #BirthdayCakeBar #ProteinSnack #FitnessFuel #SnackReview #HonestReview #OnTheGoEats #HealthySnacks

Okay
[This review was collected as part of a promotion.] Okay tastes. Kinda tastes chalky and pasty. Very sweet but does taste like birthday cake. I wish it had more sprinkles. Overall not too had if you are looking for a sweet protein source.

Taste like a treat
[This review was collected as part of a promotion.] This is a tasty protein bar. The cake flavor is well balanced and sweet. Definitely can take the place of a sweet treat with benefits. Definitely recommend it.

Not for me
[This review was collected as part of a promotion.] Unfortunately the bar came squished flat and warm...it was not appetizing for me but maybe others would love it but was not my cup of tea. Maybe a different flavor

Birthday Cake Bar
[This review was collected as part of a promotion.] ONE Birthday Cake Protein bar has 20g of protein and 1g of sugar. This bar smells like a white chocolate coated bar. It had a few sprinkles on it but they did not add any flavoring. I think this one has a decent taste for a protein bar and is on the better side for a protein bar. It has a very minimal protein bar taste and the flavoring is a really good mix so you get more of white chocolate than protein. There are 220 calories for the bar which is good for 20g of protein. It was a decent sized bar with good flavor.

Sadly this flavor wasnt for me
[This review was collected as part of a promotion.] When I got the bar it was completely flattened smashed. So I missed the pretty packaged aesthetic. It has good amount of protein. I however did not like the texture, the sprinklers or the fake cake flavor. I normally love protein bars, but this was not it for me. My picky 7 year old loved it however, because, cake!

Great way to get extra protein
[This review was collected as part of a promotion.] One Bars Birthday Cake Flavored Protein Bars are a good quick snack or meal replacement. It wasn’t my favorite flavor but it was decent. With 20 grams of protein it’s a great way to get that extra boost.

Very Filling
[This review was collected as part of a promotion.] I received One Bars Birthday Cake Flavored Protein Bars complimentary from Influenster and One Brands in return for my honest review. These One Birthday Cake Flavored Protein Bars have a nice birthday cake flavor. They are very dense and filling. I like that they contain 20 grams of protein and only 1 gram of sugar. I would highly recommend these protein bars if you are searching for a good tasting, quality, protein source.
