RUNNER-UP
THINGS WE LIKE
  • Soft and chewy
  • A great meal replacement
  • The taste is very similar to that of a brownie
  • No chalky aftertaste or unpleasant taste
THINGS WE DON’T LIKE
  • If you have a nut or soy allergy, this protein bar is not for you
  • Has a mild taste of protein powder

What image comes to your mind when you think of chocolate brownies? Do you think of soft, dough-like treats with the decadent lusciousness of milk chocolate? If so, you are in luck. ONE Bar chocolate brownie is an excellent treat with a hard-outer cover and a soft and almost gooey inside. The texture and taste replicate a chocolate brownie with perfection. It even has a layer of icing that creates a good bite.

ONE Bar chocolate brownie is sweeter than most of their other flavors. However, the sweetness is balanced by the rich chocolatey taste. You cannot miss the taste of rich cocoa that gives the bar its indulgent brown color and delicious aroma. This is a flavor that is perfect as a satisfying and delicious dessert. It is easily one of our favorite ONE Bar flavors.

8. Cookies and Crème

RECOMMENDED
THINGS WE LIKE
  • They are not overly chocolaty
  • Not overly sweet
  • Have more fiber than other similar bars
THINGS WE DON’T LIKE
  • When heated, it smells bad
  • These are high in carbs

If you relate cookies and crème to Oreo, you will most likely not be impressed by this flavor. Although it tastes like cookies and crème, it is very sweet. It does not disappoint. However, something is lacking in the cookie part of the flavor.

The ONE Bar cookies and crème flavor is very creamy. The luscious texture and chunks of chocolate cookies in it can make it feel quite heavy. The neat outer white layer makes it look appetizing. Nevertheless, it has a synthetic sweetness. It creates an unpleasant after-taste and reduces the appeal of the flavor.

Overall Rating: 6.3/10 (Above Average)

7. Pumpkin Pie

6.7
RECOMMENDED
THINGS WE LIKE
  • It tastes just like pumpkin pie filling
  • It doesn’t have a chalky taste, unlike other protein bars
  • Not too hard or soft
  • The price is fair
THINGS WE DON’T LIKE
  • The outer layer is too sweet

I bought these as a snack for my husband and he really enjoys them. The pumpkin flavor is delicious and not at all overpowering. You could definitely taste the pumpkin and it had a slight spice to it. It is not bland or too dry. There is no bad after-taste like some protein bars have.


Also, if you microwave these for about 20 seconds, they become really gooey and chewy. It’s really good that way too! The only downside is that they are seasonal so you can’t get them year-round.

If you want a great protein bar that tastes amazing and fits into your macros well then try these out. You won’t regret it.

6. Peanut Butter Cup

RECOMMENDED
THINGS WE LIKE
  • They’re not as dry or gritty as other protein bars
  • Tastes great and has very little sugar
  • Diabetic-friendly
  • I don’t notice any bad aftertaste
THINGS WE DON’T LIKE
  • It’s a bit chewy

Rarely do protein bar brands manage to replicate the balanced sweetness and saltiness of peanut butter. ONE Bar has done a decent job in this regard. Their peanut butter cup is not overly sweet or salty. The flavor profile is well-balanced. It will undoubtedly impress peanut butter fans.

The peanut butter cup protein bar is covered with a layer of chocolate. Break it and the soft, chewy inside is revealed. The unmistakable aroma of peanut butter is enough to entice your taste buds. It is soft and chewy with a very strong buttery and nutty flavor. However, it would have been better if it were thicker. Although this bar does the job, it does not exactly replicate the texture of a peanut butter cup.

Overall Rating: 7.2/10 (Good)

5. Blueberry Cobbler

RECOMMENDED
THINGS WE LIKE
  • The price is pretty reasonable
  • High in protein and low in sugar
  • They are allergy-friendly
  • Makes me think of blueberry pop tarts
  • A minimal aftertaste
THINGS WE DON’T LIKE
  • High in calories compared to others
  • They arrived melted

Great flavor and texture. I’m not a fan of the typical protein bar texture and taste so this was perfect for me. It’s chewy but still easy to chew. There was an aftertaste, but I didn’t mind it so much. The macros are pretty good, especially compared to other bars. These are an excellent choice for a daily protein bump since they’re pretty reasonably priced and have great macros!

Overall these bars remind me of blueberry pop tarts with white chocolate frosting on top. They’re filling, tasty, and easy to eat as a snack or breakfast on the go!

Overall Rating: 7.5/10 (Good)

4. Maple Glazed Doughnut

8.2
RECOMMENDED
THINGS WE LIKE
  • It tastes so much like a doughnut or maple syrup
  • Aftertastes can remind you of pancakes
  • Tastes great and easy to digest!
  • Soft and chewy
THINGS WE DON’T LIKE
  • Sometimes, they are difficult to find in stores
  • They were melted when I got them

ONE Bar’s maple glazed doughnut is a welcome change to the maple-flavored snacks that fail to deliver the signature taste of maple syrup. The brand has done an excellent job in replicating maple glazed donuts, down to the last details. It is unique and everyone should try it at least once.

The maple glazed doughnut can easily become a favorite with those who love sweets. It is difficult to find another brand that does such a good job with maple. The caramel-colored protein bar is soft and chewy. The chocolate drizzle detail adds to its appeal. Now, regarding the taste, this bar has an intoxicating yeast flavor that you will easily identify with soft, fluffy donuts. The protein bar even finishes off with the distinct and sharp sweetness of maple syrup.

Overall Rating: 8.2/10 (Very Good)

3. Almond Bliss

8.6
RECOMMENDED
THINGS WE LIKE
  • Contains 20g of high-quality protein
  • We like the flavor of almonds
  • The price is reasonable
THINGS WE DON’T LIKE
  • Contain sucralose
  • Quest bars are much lower in calories than these

Almond Bliss ONE Protein Bars are the delightful combination of almond and coconut with a chocolate coating. It tastes like an Almond Joy bar but has fewer calories and less sugar. You’ll love them!

One caution: Make sure your bars don’t get too hot. If they melt in transit or during storage, they won’t retain their original texture and the outer layer of chocolate will turn powdery inside.

The last few orders I’ve placed have been terrible, though. The coconut smell and taste is gone and replaced with an artificial smell and taste. The consistency has also changed, and the flavor isn’t as good anymore.

I would like to see the old recipe back.

Overall Rating: 8.6/10 (Very Good)

2. Cinnamon Roll

9.1
RECOMMENDED
THINGS WE LIKE
  • They won’t leave you hungry
  • There’s no hint of artificial flavor or aftertaste.
  • Its icing coated top is delicious!
  • Has a great cinnamon flavor
THINGS WE DON’T LIKE
  • During the summer, bars have arrived melted and squishy

The cinnamon roll is best described as an adventurous choice that was done right. The flavor of a cinnamon roll is not easy to replicate in a protein bar. The unique, flaky texture of the baked good can pose a challenge as it plays into the signature taste. Nonetheless, ONE Bar has managed to do it just right. It is one of the lighter protein bars that are easy to eat and enjoy.

The cinnamon roll has multiple layers of flavor that amalgamate to create the perfect sweet treat. The icing on the top delivers a crisp bite. Although it is impossible to create the same light and flaky layers of a cinnamon roll, the authentic flavor profile compensates for the difference in texture. The best part is that the taste of cinnamon is evident yet subtle. It does not overpower as it appears at the end of the bite and leaves a pleasant aftertaste.

Overall Rating: 9.1/10 (Excellent)

1. Birthday Cake

9.4
RECOMMENDED
THINGS WE LIKE
  • Each bar has 20g of protein
  • Warm it up for 10 seconds and you’ll have a nice treat!
  • Cakey, not chewy or hard!
  • It doesn’t taste too synthetic
  • Great bars for those with nut allergies
THINGS WE DON’T LIKE
  • The recipe seems to have changed recently
  • This is not good if you’re on a keto diet

Birthday cake is one of the toughest flavors to nail in a protein bar. To satisfy expectations, it should have multiple flavor levels that gel together to create a cohesive treat. Everything from the texture to the appearance and the taste must be perfect. ONE Bar has managed to get all these details right and has created an amazing treat that is irresistibly delicious.

Birthday cake from ONE Bar is a solid flavor. It is light but complex. It is not overly sweet because the sweetness is well-balanced by other complex flavors. These multiple flavors mix to create a beautiful combination. The flavor of vanilla stands out. However, it is not an unpleasant synthetic taste but is well-rounded. The protein bar even has sprinkles on the beautiful white frosting. It makes it both a treat for the eyes as well as for hungry tummies.

Overall Rating: 9.4/10 (Excellent)

One Bar Protein Bars in One Glance

Many factors make One Bar Protein bars a superior choice. For those who like icing on a protein bar, this brand exceeds expectations. Not only do you get icing, but it is delicious too. Almost every flavor has an icing layer, some with sprinkles or even chocolate chips. This simple visual detail makes the health food look like a guilty treat.

The thickness of the icing varies from one flavor to another. Nonetheless, it is usually quite dense. One Bar also delivers in terms of texture. The bars are chewy and moist. The brand also packs in generous amounts of chocolate chips, sprinkles, and nuts to make it very satisfying.

Now, if we look at the nutritional profile, the protein content is worth some attention. Each protein bar delivers enough protein and is comparable to leading brands in the market.

However, there is a catch. Each protein bar has 200 calories. If you are calorie counting, it can significantly add to your daily calorie intake. So, it may not be the ideal choice if you are diabetic or keeping track of your sugar intake.

Nonetheless, the protein bars from One Bar have a better texture, look, and flavor than various other protein bars. These protein bars taste better and look like a luxury product. And they are also worth a try due to their exciting and impressive taste profile.

To wrap it up…

If you have not yet tried the delicious protein bars from One Bar, you are missing out on a lot. These treats are as healthy as they are tasty. Whether it is to improve your daily protein intake or as a quick snack to serve you in times of need, it is a good choice.
