taste like ****

  • 5 Chocolate Frosted Donut

This product borders on false advertisement. "Deliciously whipped protein snack." There is nothing whipped about this product. This product looks nothing like the picture. The interior is dense, just like every other protein bar on the market. This is your typical protein bar cut into three round pieces. That's all. Taste is mediocre and still chalky/gritty. Glad I got these for free. I would never pay for them.

Not bad tasting! The texture is lighter and not as dense as a normal protein bar. The green interior color is actually not there. I have no problem getting rid of artificial colors. It's nice to have three pieces to snack on over time. I look forward to trying a different flavor.

Have they fixed the color and texture of these yet? Still waiting for them to look like the advertising before I buy another box.

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

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.

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.
