clif bar nut butter filled bars in wrappers

Clif Bar was making good-tasting energy bars before it was cool. And they keep releasing fun new flavors. Unfortunately, they haven’t made any big changes – until now.

Presenting Clif Nut Butter Filled Bars. What are they? Clif Bars with a nut butter filling.

Clif Bar Nut Butter Filled Bars

On the outside, these look similar to every other Clif Bar.

But on the inside, they are totally different.

These Clif Bars contain a nut butter filling. If you ask me, that’s a much better idea than simply putting nut butter on the outside.

They’re sort of like peanut butter filled pretzels. Only better.

Nutritionally, these bars would be ideal for longer-distance, lower-intensity races and adventures.

It’s no surprise to see this. Higher-fat, higher-protein energy bars are gaining popularity. Heck, even straight up nut butter is now available for use as an energy gel.

So putting nut butter into existing energy bars is a smart idea from a business perspective.

Health & Nutrition

These bars are certified organic, non-GMO, low glycemic, and contain at least six grams of plant based protein. Let’s see if they’re a good choice for you.

Ingredients (Chocolate Hazelnut Butter)


Nut butter is the first ingredient, which is fantastic. There’s also added pea protein to really boost the protein content.

The other main ingredients are oats, which are my favorite grain base for an energy bar.

While these bars are not certified gluten-free, they are practically gluten-free (for anyone who chooses gluten-free as a preference rather than a life-threatening allergy). You have nut butter, oats, brown rice, and dates – those are all naturally gluten-free foods.

There are no artificial sweeteners. The sugars come from brown rice syrup, date paste, cane syrup, and tapioca syrup.

Overall it’s a very healthy energy bar.

Nutrition Facts

(Again for the Chocolate Hazelnut Butter flavor.)

Calories 230
Total Fat 11g
Total Carbs 27g
Fiber 3g
Sugars 10g
Protein 6g

*Note that most flavors contain 7g protein, even though this one was only 6g.

This is unmistakable as an energy bar.

It’s a slightly more balanced energy bar, so it has a decent amount of fat and protein, but there are still lots of carbs. And really not that much protein.

Make no mistake – this is still a bar for someone with an active lifestyle. It’s just not the bar you’d eat during an intense race!

Taste Test

While all the bars are filled with some type of nut butter, and you might have a simple flavor like “Peanut Butter,” there are some more interesting flavors, too!

Here are my thoughts on each flavor of the Clif Bar Nut Butter Filled lineup:

Peanut Butter

The peanut butter filling is great. It’s soft, melts easily, and has a similar flavor to a peanut butter cookie!

Unfortunately, the texture of the bar itself is not the same as the soft, chewy oat layer on the fruit smoothie filled bar. This one is more of a hard shell, which isn’t very enjoyable.

So, even with what seems like a real peanut butter filling, this bar isn’t that good. And it’s definitely not as satisfying as a peanut butter sandwich. (And since a peanut butter sandwich is easy to make and cheaper than a Clif bar, I’ll stick to the real thing.)

Chocolate Peanut Butter

This bar is nothing more than the peanut butter bar with some cocoa powder added to the dry ingredients in the outer shell. So you have a chocolate Clif Bar that’s filled with peanut butter.

From the outside, it looks like a no bake cookie! (Which makes sense because it uses similar ingredients.) Naturally, this bar is not as good as a homemade no bake cookie, but that seems like the flavor they’re going for.

I consider the chocolate shell to be boring. I’m no chocolate connoisseur, but I’m thoroughly unimpressed with that. However, there is a substantial amount of peanut butter inside! And this creamy peanut butter filling is delightful!

So basically the outside is hard and bland and the inside is super creamy and flavorful.

Put them together and it’s not bad, but it’s not great. It ain’t no Reese’s cup! I wouldn’t bother buying this again.

Coconut Almond Butter

This flavor sounds strange, and it’s definitely something different I’m not used to (in an energy bar), but it’s pretty good. It’s similar to an iced oatmeal cookie, just a little less sweet. It’s mostly oatmeal flavor… followed by some soft, delicate sweetness.

On the first bite, you taste the oatmeal and just a hint of sweetness. Then as you get into the filling, there’s more sweetness.

Yes there is some coconut flavor, but it’s light. It reminds me of baking with coconut oil rather than butter. There’s just that hint of coconut.

Don’t get too excited though. It’s about as good as a store-bought iced oatmeal cookie. You know, the ones that look really good but it turns out they are a few days old because people don’t really buy oatmeal cookies, and you don’t realize it until after taking a bite and you just know it’s not fresh.

Maple Almond Butter

Finally an interesting flavor! I was excited for this one, and upon opening the package I was greeted with the strong scent of maple.

The first bite tastes like any other Clif Bar… just your rice and oats flavor… then the maple hits!

Well, not authentic maple, exactly. It tastes like I’m eating French toast sticks with syrup!

Not French toast. And not maple syrup.

It’s specifically like French toast sticks – either fast food or the frozen ones that come in a box and you cook yourself. That combination of batter, artificial maple flavor, and (most prominently) regular syrup flavor.

The maple flavor was strong enough to overpower any almond or cashew flavor in the filling. Surprisingly, there was no similarity to any of the maple syrup flavored energy waffles I’ve tried from Honey Stinger or GU.

As with the other flavors, I wish the outer shell was softer. If they could soften the outside, I’d buy a box of this flavor. But as is, no thank you.

Overall… it’s good, but it’s not as good as eating French toast sticks.

Chocolate Hazelnut Butter

I haven’t tried this one yet, but I imagine the filling tastes exactly like Nutella.

Banana Chocolate Peanut Butter

This bar is like a peanut butter Nutella banana sandwich. It has a lot of flavors in one bar! It’s quite tasty, and even though it doesn’t blow me away, it’s a lot better than some of the other flavors.

I also really liked that it is less messy than a typical chocolate bar, because here, all the chocolate is contained inside. The chocolate is only in the filling, so it doesn’t melt and smear everywhere like chocolate coatings do.


Caramel Chocolate Peanut Butter

Unfortunately I never got to try this one. I imagined it tasting like those pretzel sticks that get dipped in caramel and then dipped in chocolate. (But here it would be extra fancy because it would be a peanut butter filled pretzel stick that’s then dipped in caramel and chocolate!)


Blueberry Almond Butter

Unfortunately I never got to try this one. I imagined it tasting like blueberry pie filling inside a stale, hard pie crust.


None of these were as good as the fruit smoothie filled bars.

I was disappointed that these were not as wonderful as the fruit smoothie filled bars.

The texture of those bars seemed softer and fluffier – more homemade – than these nut butter filled bars.

It’s so strange because the bars are basically the same thing. It’s just the fillings that are slightly different.

[If you want nut butter filled bars, try the ABC Bars from Trader Joe’s. They’re amazing.]

Who Are These Best For?

These bars are low-glycemic. They will digest more slowly than regular Clif Bars due to the added fat, which means they’ll provide energy over a longer period of time.

On the flip side, that means you don’t get an instant boost of energy. As such, these are best for long and steady types of workouts and races, or more recreational activities like hiking.

One thing I really like, which is a benefit for any time you might be using these – even at your desk for an afternoon snack – is that the bars are not messy.

There is no chocolate coating to melt. It’s all on the inside. You either have chocolate baked into the bar or as part of the filling.

These are the same as regular Clif Bars… but different.

Where to Buy

These bars can be found anywhere Clif Bars are sold, so you’ll probably find them in grocery stores, sporting goods stores, nutrition & supplement stores, and of course, Amazon.com.

The retail price is $1.79 for a single bar or $19.08 for a box of 12.

Expect to pay around $1.50 each in stores (or $15 for a 12-pack).

My final verdict is…

These bars were a great idea. I’m glad Clif Bar made them. Now I hope that either Clif Bar improves them, or a competitor makes something similar that tastes better.

Because, unfortunately, these bars are lackluster. They’re not bad, but they’re basically a hard flavorless shell surrounding a couple small bites of creamy nut butter. (Especially disappointing after how good the fruit smoothie filled bars were.)
