Guests are saying
The reviews for the protein bars are quite varied, with guests expressing strong opinions on both sides. Some guests are enamored with the birthday cake flavor, praising its ability to satisfy sweet cravings while providing a substantial protein boost. Others, however, are critical of the taste and texture, finding them unpalatable and disappointing. The bars seem to be a hit or miss, depending on personal preference for texture and sweetness levels.

Love them!
[This review was collected as part of a promotion.] Not gunna lie, I have a super sweet tooth and this one REALLY hits the spot for me. Whether it’s for breakfast, lunch, dinner or a snack, the Birthday Cake protein bar a wonderful addition to my Quest rotation.

Disgusting
[This review was collected as part of a promotion.] out of all quest bars, this one is awful and definitely the worst. It is super chewy and waxy, and there is little no birthday cake flavor. I got major stomach issues after eating this one specifically.

I LOVE THIS BAR
[This review was collected as part of a promotion.] I don’t usually go out of my way to review stuff, but this is a FANTASTIC protein bar that I eat religiously to supplement my protein and calorie intake on busy days. I eat at least three or four of these a week and I’m never disappointed. These and products like these have helped me lose 40 pounds in the span of about three months. But the birthday cake flavor is my FAVORITE. They taste great and satisfy my sweet tooth without sugar. I love the chewy, dense texture and the icing that coats it. They aren’t crumbly or messy or melty so I can eat them on the go. I throw one in my purse every morning. I feel like I’m getting a sweet treat but they are almost sugar free and full of protein! Thanks, Quest! And please never discontinue or change this product! It is perfection!

So disappointed
We usually LOVE these bars but each one seems all dried out and crumbly. (Sad face)

Birthday month
[This review was collected as part of a promotion.] I love the fact that I don’t have to go to Cirkle K to get me a birthday bar, now I can grab one from my own pantry. I really love the taste of these bars.

Delicious
[This review was collected as part of a promotion.] I consider five star as being a super super number and unfortunately I don't think your product is a five star. It is delicious and very rewarding and I appreciate having it, but I don't consider it to be a five star.

Birthday cake
Love the chewy feel to it and the sweetness is just enough to satisfy the sweet craving. I used it as a dessert, since I’m on GLP-1 med.

Tastes like a yummy condensed birthday cake
[This review was collected as part of a promotion.] Birthday cake is literally one of my favorites that in the Strawberry Shortcake! This Bar is unbelievably good and you would never think that it was actually healthy for you. I will always have it in my cabinet

Past sell date...
These are OK but I just realized my bars were expired by 3 months… I should have at least gotten a discount for them. Double check those labels!!

These Quest Birthday cake flavor is so good
These Quest Birthday cake flavor is so good. No gritty or chalky texture either. Make sure you pay attention to the box because there are two types. You want the one with the Birthday cake with 20mg stamped inside and tasty looking piece of cake on the front.

Birthday Cake Surprise
[This review was collected as part of a promotion.] First time buying the Birthday Cake Protein Bars, and I was pleasantly surprised. I bought them to enhance my grandchildren's after lunch snacks, but after trying them myself, I'm now a true fan of this new addition. The taste is very pleasant, not too sweet, and just right on my palate. I would recommend these to anyone looking to make a change for the better, in snacks mid-day or an addition to your daily regimen.

I love the birthdaycake protein bar 10/10
[This review was collected as part of a promotion.] Birthday cake? More like "vanilla rainbow heaven sprinkles unicorns hearts and glitter" if it was a protein bar, THIS IS THE BEST FLAVOR OF QUEST protein bars!!!! (in my opinion). A MUST-TRY!💖🎂🍰

I love birthday cake flavored things, but there's something sickeningly sweet about the coating on this bar. I hope Quest tries a new formula at some point!
