Need a quick low-carb snack option?

We’ve had a lot of requests from readers asking which flavors of Quest Bars are the best, so I decided to do a little taste test on some of their most popular flavors – 15 to be exact! I started out with the intention of ranking them, but after the 10th bar, it was getting a little hard to pinpoint the exact order.

So to be fair, I decided to give you a little feedback on each one, and I’ve placed star emojis next to my own personal favorite flavors.

We realize that many consider these bars to be dirty keto, so please keep that in mind when deciding if these bars are something you want to add to your snack options.


On to the taste test…

peppermint bark quest bar in box

⭐️Peppermint Bark⭐️

Serving Size: 1 Bar | 190 calories | Fat: 7g | Total Carbs: 22g (Fiber: 14g | Erythritol: 4g) Net Carbs: 4g | Protein: 21g

This is HANDS DOWN my absolute favorite Quest Bar! It’s like Christmas in my mouth and I can’t get enough. It seems like everyone else loves this flavor too as the entire display from Publix was empty within a few days. 😩 Unfortunately, this is a seasonal flavor so if you’re like me and you really like it, you might want to stockpile a box or two.


Quest protein bars

Caramel Chocolate Chunk

Serving Size: 1 Bar | 190 calories | Fat: 7g | Total Carbs: 23g (Fiber: 15g | Erythritol: 4g) Net Carbs: 4g | Protein: 20g

I’m not going to lie, the packaging got me. I (foolishly) opened it thinking that I was going to be biting into some sort of sugar-free Caramello candy bar… what I found was just a regular Quest Bar. It tasted more like caramel but not much of a chocolate taste. Not bad, but not what I was expecting based on the packaging! 🤣 To be fair, all of the packaging shows something that isn’t quite the same as the Quest bar, so maybe I was really wanting a candy bar that day.


cookies cream quest bar

⭐️Cookies & Cream⭐️

Serving Size: 1 Bar | 200 calories | Fat: 8g | Total Carbs: 21g (Fiber: 15g, Erythritol: 2g) Net Carbs: 4g | Protein: 21g

This bar is one of my favorites because the aftertaste isn’t so strong. I really like heating it up in the microwave and making it into a cookie or cake form and adding a little Kerrygold butter to it! YUM!


blueberry quest bar on table

Blueberry Muffin

Serving Size: 1 Bar | 190 calories | Fat: 7g | Total Carbs: 22g (Fiber: 15g, Erythritol: 2g) Net Carbs: 5g | Protein: 21g

I love that you can actually taste the blueberry in this bar. It’s a pretty pronounced flavor, and it would be great to grab for a quick breakfast bar – but wasn’t up there as one of my favorites.


quest mint chocolate chip bar

⭐️Mint Chocolate⭐️

Serving Size: 1 Bar | 200 calories | Fat: 8g | Total Carbs: 22g (Fiber: 16g, Erythritol: 2g) Net Carbs: 4g | Protein: 20g

I seem to be on a mint kick lately given the holiday season so this bar feeds my craving! It’s yummy and doesn’t have a strange aftertaste. It’s a close second to the Peppermint Bark for those of you that love minty treats.


quest mocha bar on guitar

Mocha Chocolate Chip

Serving Size: 1 Bar | 180 calories | Fat: 6g | Total Carbs: 24g (Fiber: 14g, Erythritol: 6g) Net Carbs: 4g | Protein: 20

OK all you coffee fanatics, this is the bar for you! I’m not a coffee drinker so this bar is not one of my favorites. It doesn’t taste bad at all, but it is for sure heavy on the mocha flavor.


double chocolate chunk quest bar

⭐️Double Chocolate Chunk⭐️

Serving Size: 1 Bar | 180 calories | Fat: 7g | Total Carb: 24g (Fiber: 14g, Erythritol: 6g) Net Carbs: 4g | Protein: 20g

A good go-to when you need a little chocolate fix. I actually like to cut this bar up into small pieces and just grab a couple at a time when I have a chocolate craving. It’s definitely one of my faves!


quest bars scattered on table

Chocolate Chip Cookie Dough

Serving Size: 1 Bar | 200 calories | Fat: 9g | Total Carbs: 21g (Fiber: 14g, Erythritol: 3g) Net Carbs: 4g | Protein: 21g

Cookie Dough lovers, rejoice! This bar has the delicious cookie flavor you’re looking for without a ton of carbs. I like that there’s no weird aftertaste with this bar as well.


quest hazelnut bar

Chocolate Hazelnut

Serving Size: 1 Bar | 190 calories | Fat: 8g | Total Carbs: 23g (Fiber: 14g, Erythritol: 5g) Net Carbs: 4g | Protein: 20g

The minute I saw this flavor, I had dreams of a bar that would taste like Nutella. Sadly it doesn’t. It’s not bad, I just wish it had a stronger hazelnut flavor. It for sure has a nutty flavor, but not really Hazelnut in my opinion.

⭐️Birthday Cake⭐️

Serving Size: 1 Bar | 180 calories | Fat: 6g | Total Carbs: 24g (Fiber: 14g, Erythritol: 6g) Net Carbs: 4g | Protein: 21g

This bar is such a treat! I’m not typically a “eat all the birthday cake things” kind of person, but this bar tastes and feels like a candy bar with the way it is coated. This is one of my typical go-to flavors and I usually have a couple in my bag for a quick on the go snack.


quest chocolate peanut butter bar

⭐️Chocolate Peanut Butter⭐️

Serving Size: 1 Bar | 210 calories | Fat: 10g | Total Carbs: 22g (Fiber: 13g, Erythritol: 4g) Net Carbs: 5g | Protein: 20g

This bar delivers! Absolutely no weird aftertaste and it has the chocolate peanut butter flavor I crave! While it’s certainly not a Reese’s, it’s still tasty. This is another one that I love to heat up in the microwave—if you don’t do this with your bars, you’re missing out! This bar is for sure a must-try.


oatmeal chocolate chip quest bar on table

Oatmeal Chocolate Chip

Serving Size: 1 Bar | 190 calories | Fat: 7g | Total Carbs: 23g (Fiber: 16g, Erythritol: 2g) Net Carbs: 2g | Protein: 20g

This bar reminds me of spice cake more so than Oatmeal Chocolate. However, I feel like I can taste a hint of raisin, giving it the oatmeal cookie effect.


quest bars on drumhead

⭐️Chocolate Brownie⭐️

Serving Size: 1 Bar | 180 calories | Fat: 6g | Total Carbs: 23g (Fiber: 17g, Erythritol: 2g) Net Carbs: 4g | Protein: 20g

This one has a similar taste to the Double Chocolate Chunk and is a great go-to when you need that chocolate fix without falling off the keto wagon!


quest bars on drum

White Chocolate Raspberry

Serving Size: 1 Bar | 200 calories | Fat: 8g | Total Carbs: 22g (Fiber: 15g, Erythritol: 2g) Net Carbs: 5g | Protein: 20g

This bar surprised me the most. I’m not really a white chocolate or raspberry fan but this bar was good! The raspberry reminded me of a jam or jelly flavor, while the white chocolate was not as pronounced.


quest smores bar on table

⭐️S’Mores⭐️

Serving Size: 1 Bar | 190 calories | Fat: 7g | Total Carbs: 22g (Fiber: 14g, Erythritol: 4g) Net Carbs: 4g | Protein: 21g

This bar is another of my favorites. I wouldn’t really say it’s a strong S’Mores flavor, but it’s still pretty delicious with a little bit of a honey taste to it.
