Good sweet craving
Really happy with these ONE Protein Bars in the Birthday Cake flavor. The texture is soft and not too chewy, and the flavor actually tastes like birthday cake without being overly sweet. 20g of protein and only 1g of sugar makes them a great grab-and-go snack. I took off one star because the aftertaste is a tiny bit artificial

New Blueberry Cobbler Recipe is DIFFERENT AND WORSE
As of early January 2026, they have changed the recipe of the blueberry cobbler, getting rid of the cocoa butter and subbing in almond butter. Not sure what else they did, but if you enjoyed the sweetness of the old ones, and the easy to chew texture, the bars are COMPLETELY different, lost the smooth sweetness, made the texture more coarse, and the colors are awful, more brownish as if they've all gone off. You'll noticed the wrapper is slightly different. The one on the top is the GOOD, old version. The darker label is the newer version. If you sub and save to these bars, you may want to cancel. I cannot believe they messed with "my" recipe. These were my go-to, "guilty pleasure" on a fairly low sugar diet. They were filling, had an ok amount of sugar alcohols, and if you eat too much in a day, your tummy wouldn't thank you, but I'd rate them five stars every time. It's so hard to get good fruity flavors in a chewy protein bar. Now I have to go searching and spending money trying new bars to find a new favorite. Oh well! I just wanted to warn everyone that they did change and NOT for the better!!!

I always buying this brand and I love peanut butter cup and peanut butter cups , if it wasn’t pricey, It was my everyday snack ! I read lots of bad reviews about the taste of other flavours but peanut butter is amazing! I found it on amazon cheaper so I ordered a box ! I was so exited to get them but when I opened the box, it was 1 months to expiry date!! I tried to return it online and I saw it’s not eligible for return!! I called amazon, customer service and support was great, I got full refund . I wanted to tell you that this brand( peanut butter flavour ) is great, amazon customer service is great but don’t trust the seller !

There is a weird aftertaste that will not make you complete the bar. I try it and give it to some of me friends and all of us agree that the is a bad aftertaste and we throw it away.

I like the flavor and texture. I don't like the price especially since I received 11 bars instead of the 12 that should be in the box.
