Great way to get a sweet fix while still getting protein. Good taste, but obviously not the real thing. IF you are a big protein bar person this should be a nice change.

  • 5 Birthday Cake

While this product wasn’t disgusting, it wasn’t that great either. I agree with most of the other reviews,the texture was not as described. It was not “whipped.” It was dense like a typical Quest or whey based protein bar. It was chewy, not creamy or light. The flavor wasn’t bad. It tasted like every other “birthday cake” protein bar I’ve had. The only difference between this and any other protein bar is that it’s broken up into 3 small pieces. I bought a 4 pack, so I will eat the remaining 3 packages but for the money, there is cleaner and better protein bars out there.

  • 1 Peanut Butter Chocolate

Really disappointed by these. The Peanut Butter Chocolate was very chalky and had absolutely no peanut butter flavor. The texture was extremely chewy and dense, not whipped or cake like at all. It was honestly a struggle for me to finish it and I won't be purchasing again.

Such a yummy convenient little treat!

  • 10 Blueberry Cheesecake
  • 10 Chocolate Mint

Absolutely loved these! I was worried when I read some of the reviews but decided to give them a try. The texture is super soft and sweet enough for when I’m craving sugar. I will definitely buy these again and I cannot wait to try some of the other flavors. Very happy I found these.

  • 4 Chocolate Dipped Cherry

Clay. It's 3 disks of flavored clay. Just like most protein bars. It is definitely softer than some brands rectangular bars but the tasts and texture is nothing resembling cake in any shape form or fashion. Not worth paying more than some other protein bars with more protein, or better macros for something that isn't more appetizing. For this item I'd buy at $1/pack. Any higher of a price point and I absolutely would make a different choice. Not recommended.

I rarely by protein "food" stuff (I stick with whey isolate powder if I need to supplement). However, I tried these cake bites because of my curiosity and my love for Optimum Nutrition. The "Chocolate Mint" was the first I tried, and I was hooked. I opted to buy a full 12-pack box because I'm always sorry that I've run out after eating an individual package of 3. There's a slightly less than subtle mint flavor with the chocolate outside. You really can't go wrong. I tried "Blueberry Cheesecake" after that to expand my horizons. That was a mistake. Logically, "Blueberry Cheesecake" bites taste like the protein powder of the same flavor. Also, it's covered in white chocolate rather than the milk/dark chocolate of the other flavors. I'm not a fan, but many are. If you liked ON's blueberry protein powder, then this cake bite is for you. I risked the "Chocolate Dipped Cherry" today despite the low rating, and I really liked it! The cherry flavor is very subtle. I worried that it'd be like cherry medicine given the poor rating, but it isn't like that at all. As far as imitation cherry flavor, it's closer to cherry juice. Chocolate Dipped Cherry and Chocolate Mint are definitely my favorites so far. I'm looking forward to trying the other flavors, too.

As other reviews have stated, my biggest pet peeve is the somewhat false advertising of the product, especially the first time I tried them. I was somewhat disappointed when the product didn’t match the package description and picture. The texture is nothing like cake or anything “whipped” as the package states, but it is really soft and not chewy like some bars. Just don’t go expecting a cake or 3 Musketeers-like texture. Flavor wise, the ones I’ve tried have been really good, with Berry Cheesecake being my absolutely favorite. Misleading desciption aside, these are a pretty good protein snack that I keep coming back to. Will be ordering more!

  • 1 Birthday Cake

Honestly, I’m really upset with this. I expected these to look like the picture, taste exactly how it’s described, but they look absolutely horrible and are almost unedible. I’ll give credit where credit is due, I did get 20g of protein, but it the texture is like clay and the taste sticks with you for a long time after your done. I won’t be buying anymore of this product, I’m truly disgusted with it.

  • 4 Birthday Cake

Didn't like the birthday cake bites very much. They're better if you microwave them for like 20-30 seconds. I'd try the other flavors, but I won't be buying this flavor again.

  • 3 Red Velvet

Really dense, like eating clay, and the red velvet didn't taste like red velvet. Honestly the only good thing I can say is that it's a quick way to get 20g of protein, but I don't think it's anywhere near worth the money and I couldn't eat this as an actual snack, it's more of a chore. Can't recommend the red velvet, and won't be trying other flavors.

Tastes pretty good. Good source of protein. Something sweet without any guilt. I definitely will buy again

  • 7 Chocolate Mint

Taste was pretty good, but not as visually appealing as the photo. Shape is not uniform, protein is not really whipped and despite the chocolate mint showing a green filling, the filling looks a dull yellow just like the frosted donut variety. Nothing more than bite size protein bars. Not terrible, but nothing like the decadent treat the advertise. I'll probably buy one more box of a different variety and if no improvement they are done in my book.

The bar tastes really good. But it has only Whey concentrate as the main ingredient which is so below standard for such a huge brand at this price.
