The Best Dark Chocolate Bars, According to Our Tests

We tasted dozens of dark chocolate bars from brands including Alter Eco, Pascha, and Raaka.

If you’re reading this, we’re betting we don’t have to tell you how amazing dark chocolate is. The higher percentage of cacao in dark chocolate is the secret to so many of our favorite chocolate desserts, like these simple dark chocolate vanilla cookies or this classic molten chocolate cake.

But let’s be real: You don’t always feel like breaking out the baking tools and cookie sheets when you’re craving a chocolate fix. Sometimes, a bar of the best dark chocolate is all you need to hit the spot. With so many options, finding truly high-quality chocolate can be quite tricky. That’s why we recently taste-tested 15 of the best dark chocolate bars. We also chatted with a registered dietitian to get some additional expert insights.

After blind-tasting dozens of popular dark chocolate brands, we found ten clear winners for snacking. These bars all contain 70% or more cacao, and happily, many of them don’t cost much more than a latté.

At $10 per 3-ounce bar, this is certainly not the cheapest chocolate bar on our list. However, it was undeniably one of our favorites in our taste test. The cacao used in this bar is entirely from the Dominican Republic, and the result is chocolate with a strong sense of place (not to mention, an incredibly fragrant scent and brightly fruity, intensely floral flavor). There’s a pleasantly bitter finish that reminds us of citrus peel and pith.

The Dos Rios bar has a clean snap and a smooth exterior, indicating a high quality of craftsmanship. The texture of the chocolate, as it melts, is stunningly smooth with no perceptible grittiness; it ranked 4.67 out of 5 on our smoothness scale. The ingredient list is impressive, too, with whole vanilla beans used to enhance the cacao. We feel this thoughtfully-made bar provides a luxurious sensory experience if you can swallow the cost.

Decidedly not a pick for the milk chocolate crowd, this deep, dark bar contains 85% cacao. It’s moderately dark in color; the coffee and mocha-hued tones combined with a glossy, low-shine coat make it an attractive, enticing bar. It ranked neatly in the middle on both our earthy and fruity scent scale, giving it a nicely balanced, crowd-pleasing profile.

The snap is satisfyingly sharp, but the real reward comes to the patient connoisseur. The slow-to-melt texture starts as intensely bitter but reveals notes of rich roasted coffee and toast as it begins to warm and soften. There’s a moderate tongue-coating finish that’s refreshingly devoid of tannic bite. The price — around $4 per 3-ounce bar — is hard to beat, as is this brand’s ubiquity. It’s stocked in many natural grocers and markets.

With a saturated, rich “true brown” hue and moderate gloss, this bar has a classic, inviting aesthetic. The scent was surprisingly subdued for an 80% bar; at least three of us described it as mellow (though in no way unpleasant; it was fun to uncover some subtle aromas more familiar with beer, like hops, malt, and yeast). There was an audible, almost aggressive snap without any dust or fine shards.

It’s quite bitter — to be expected of a higher percentage of cacao — but during the taste portion of our test, we noted that came from a “cacao-forward” flavor profile, backed up with gentle floral notes. The K’UL bar, more than most we tested, became more pronounced in all its flavors as it melted, growing louder in both tannins and bitterness, but floral and fruit too. The finish is surprisingly short and doesn’t leave any film or stickiness in the mouth. Unlike most dark bars, this one contains no vanilla: just cacao, sugar, and cocoa butter.

K+M Chocolate is the result of a collaboration with Chef Thomas Keller and olive oil producer Armando Manni. The bar we tasted in this review contains an impressively high 85% cacao, which is sourced exclusively from Ecuador. It’s stunningly dark, velvety, and glossy; we noted it had a distinctly “luxurious” aesthetic immediately upon viewing. There’s a bark-like aroma that leans heavier toward the “earthy” end of the scale.

The from-the-earth aromas followed through on the palate, calling to mind woods, campfire, and, again, pure cacao nibs. The texture is pure indulgence: A K+M bar is almost impossibly velvety with a full mouth-coating sensation that further reveals notes of lemon, tea, and bourbon. This is one of the most expensive bars we tasted and the packaging is highly attractive, making it one of the most giftable chocolate options on this list. It’s a bar for savoring, not inhaling, with one of the most unique flavor profiles we’ve tried.

Although many of the bars we tested are naturally vegan and gluten-free, Pascha’s 85% bar is one of the most food allergy-safe options you can buy. It’s certified free from the top eight allergens (including soy and tree nuts) and is made without emulsifiers. But equally important is the experience of, you know, eating it. Happily, that’s a five-star experience, too. This bar is a deep nut brown, falling somewhere between tawny and hickory on our color scale, and has a consistent gloss.

Pascha’s 85% bar received a 3 out of 5 on both the earthy and fruity scale, solidifying its classification as a balanced, moderately aromatic bar that will likely please a wide variety of dark chocolate lovers. It presents an initially strong nutty flavor that releases smoky, berry-forward flavors and an inviting smoothness as it melts. It’s one of the least expensive bars we tested, earning it a top spot on our list for any bar — not just an allergen-free one.

During our tests, we tasted Raaka’s Philippines 71% Classic Dark Bar, a cult-favorite chocolate bar so popular that it frequently sells out. However, this trio includes two dark chocolate bars that we think will satisfy any dark chocolate craving — the 71% Pink Sea Salt and even darker 85% Bourbon Cask Aged. Fans of Raaka appreciate the single-farm sourcing and unroasted cacao, which sets this brand apart from the pack.

In our taste test, we found the aroma of the bar was well balanced with a hard-to-define tone many of us described as “classic” or “straight” chocolate. It broke cleanly and “without drama,” although we noted that the lack of preformed segments made it difficult to portion — however, we did feel it’d be great for chopping and using in a recipe. There were intriguing smoky notes upon first taste; campfires, coffee, and mezcal were all invoked. There’s a bracing astringency that lingers, with the raw cacao taking center stage long after the chocolate has been eaten. Although unroasted cacao can be polarizing, we think this is one of the most successful raw brands around.

Although Theo doesn’t crow about it on this bar’s packaging, the cacao is single origin, all sourced from the Democratic Republic of Congo. The bar is a woodsy brown color with a slightly matte finish and is sectioned into big squares perfect for snacking. The aroma is mellow and mild, with subtle notes of black tea and nuts. It had one of the most deliciously satisfying snaps of all the bars we tested.

The tannins and astringency of a good black tea are again present on the tongue, with almond undertones and a slightly chalky texture. With time, the intense flavors gave way to gentler fruity notes, and the texture softened and smoothed. Theo’s bar had a bold, unapologetic finish that many of us thought would shine in a bittersweet chocolate recipe, like flourless chocolate cake. Theo’s 85% bar is not for the faint of heart, and that’s exactly what many dark chocolate fans will appreciate about it. 

Another bar for the deep, dark crowd, this was an editor’s pick for a truly intense bar that doesn’t back down on the cacao-forward flavor. “Alter Eco bars have been my favorite for a few years now! The 85% is great, but I have no self-control with the 90%. I tell myself it doesn't count as candy,” says associate editor Mary Lagroue.

Alter Eco’s Classic Blackout is a blend of Ecuadorian and Dominican cacao that’s married by Swiss chocolatiers (how’s that for international influence?) The result is a well-balanced, bitter bar that’s malty and fruity in equal parts. The 85% bar is part of Alter Eco’s “Blackout” collection, which includes raspberry, orange, and almond blackouts — all made with 85% cacao — as well as a 90%, 90% mint, and breathtaking 100% bar.

The Jcoco Prism Box is another editor favorite, tailor-made for gifting a chocolate lover. “I like Jcoco’s mix box which has both classic and other flavors,” says associate editorial director Megan Soll. The box includes ten wildly unique flavors (black fig and pistachio, edamame sea salt, and orange blossom espresso, to name a few), and the bars are packaged in brilliantly bright paper that evokes a rainbow prism when lined up in the box. Each bar is a full ounce of chocolate, and the cost of the box — gift packaging and all — is under $40.

We particularly like the variety of cacao amounts here, with bars ranging from 47 to 71%. There’s even a 30% white chocolate bar made with cayenne and orange for the perfect balance of spicy, bitter, and sweet. Even sweeter is the mission behind the Jcoco Prism Box: A percentage of each purchase goes to fighting hunger right here in the United States.

Tony’s Chocolonely is making waves in the chocolate world, not just because of its commitment to ethical sourcing (99% of ingredients are Fairtrade certified), but also because it invests in its employees and the environment: The brand is B Corp certified. 

This bar was an editor’s choice for the creamiest dark chocolate bar, owing to the ratio of cacao to cocoa butter. “Even people who don’t generally love dark chocolate seem to love this bar from Tony's Chocolonely because it’s so creamy and not overwhelmingly bitter,” says commerce editor Danielle St. Pierre. It’s dark enough to satisfy fans of bitter and complex flavors, but still super smooth with an impressive meltability.

How We Tested Dark Chocolate

To properly evaluate the chocolate bars, we created a testing protocol that was entirely blind. First, we removed each bar from its packaging and scraped off any identifying marks or branding. Our testers were instructed not to wear perfume or scented products, so as not to influence the sensory experience of tasting the chocolate, and we cleansed our palates with water and saltine crackers between each bar.

We evaluated each dark chocolate bar based on the following metrics:

  • Appearance: To perform the test, we first took notes on the physical appearance of the bar, identifying whether it was smooth and glossy (signs of well-tempered chocolate) or dull and matte.
  • Texture: We snapped the bar, noting whether it broke cleanly (again, indicating proper tempering) or crumbled.
  • Color: We also used a color chart to note the hue of each bar, ranging from light brown tones to very dark.
  • Aroma: We smelled each chocolate bar, scoring them on an earthiness and fruitiness scale.
  • Taste: We placed a small piece of dark chocolate in our mouths and evaluated the immediate texture (gritty or smooth), and initial flavors. As the chocolate melted, we noted any evolving flavors, as well as the aftertaste of the bar.
  • Value: Once the prices were revealed, we considered whether the cost represented a good value for the quality of each bar.

Factors to Consider

Ingredients

There’s a big range in flavor when it comes to the percentage of cacao in a dark chocolate bar. Some brands consider anything above 50% cacao to be dark chocolate, although for this test we only reviewed 70% and above. The higher a bar’s cacao percentage is, the more bitter it will be — this is in part due to cacao’s inherently bitter flavors, but also because there will conversely be less cocoa butter.

All chocolate bars — except 100% cacao — are sweetened, so you can expect cane sugar on the list of ingredients; in the case of gourmet dark chocolate bars, we recommend steering clear of syrups and alternative sweeteners. You’ll also likely see vanilla on the list of ingredients; this is used as a subtle flavoring agent. Be sure the bar you choose is made with pure vanilla extract or real vanilla beans, rather than vanilla flavoring. 

Sourcing

Many high-end chocolate bars are certified by Fairtrade International, an accrediting organization that ensures farmers, growers, producers, and artisans are compensated ethically for their time, labor, and product. As with the “organic” classification, goods can be produced ethically and with fair or direct trading practices, but they lack the official label. Regardless, check the chocolate bar’s packaging before buying: If the company practices ethical sourcing, it should indicate that on the bar.

Use

All the bars we reviewed here are made primarily for snacking; you can eat them straight out of the package. Baking chocolate usually (though not always) contains less sugar; in the case of “baker’s chocolate,” it’s 100% cacao. This is because it’s meant to be added to a recipe that already contains a sweetening agent, like granulated and brown sugar in the case of chocolate chip cookies. On that note, baking chips and discs contain stabilizers that help them hold their shape in a hot oven. You can use most snacking chocolates for baking — just chop them roughly with a knife — but be aware their sugar content may alter the overall flavor of your finished product.

Frequently Asked Questions

  • What does dark chocolate mean?

    “Dark chocolate is made from cocoa, or cacao, which is the dried and fully fermented fatty seed of the fruit of the cocoa tree,” says Jamie Vespa, a Registered Dietitian and the recipe developer behind Dishing Out Health. “Dark chocolate has a higher percentage of cocoa solids (50-90%) compared to milk chocolate, and no added milk solids.”

  • Is dark chocolate good for you?

    Vespa says that compared to milk chocolate, dark chocolate contains less sugar and has more beneficial minerals and polyphenols; notably flavonoids, which can have anti-inflammatory qualities and may improve vascular function and lower stress. Vespa says, “One ounce of dark chocolate can contain anywhere from 10-20% DV of manganese, magnesium, copper, and iron,” and adds that a 1-ounce serving of dark chocolate with at least 70% cacao is the best way to reap the health benefits.

  • Does dark chocolate contain caffeine?

    Yes, although it won’t get you as amped as that afternoon cup of coffee. “Caffeine is present in small amounts (about 0.2% by weight) in dark chocolate,” says Vespa. “It also contains a compound called Theobromine, which has antioxidant activity similar to caffeine, and a mild stimulant effect.”

  • Should I be worried about heavy metals in chocolate?

    After a 2022 Consumer Reports article shared findings of cadmium and lead in household chocolate brands, there’s been a greater awareness among chocolate fans about the potentially harmful effects of eating dark chocolate. Says Vespa, “As with many other food products that may contain trace metal contamination, moderation is key,” adding that, “for pregnant persons and young children, it may be best to choose only those brands found to be lower in lead and cadmium by the Consumer Reports article.”

Other Dark Chocolate We Tested

Endangered Species Dark Chocolate Bold + Silky 72% (Walmart)
The Endangered Species chocolate brand is found in most well-stocked grocery stores, and retails for around $4 per bar, making it a great deal for an impulse chocolate fix. In our review, we were impressed by the very clean, strong snap of the bar, and liked the “classic chocolate” flavor that wouldn’t likely rock anyone’s boat. But some of us found the aftertaste unpleasantly tannic and the texture gritty. It’s a solid bar, but not quite as special as our top picks.

Beyond Good Organic 70% Madagascar Dark Chocolate Bar (Amazon)
At 70%, this is one of the lowest cacao percentage bars we tested. The initial appearance of this bar underwhelmed us; we described it as being “dusty,” “dull,” and “crystallized,” with “an opaque cloudy coating.” It has an almost overwhelmingly savory flavor, which many tasters found interesting (and reminiscent of ingredients like bay leaves and soy sauce). The short finish and bitter, slightly over-roasted flavor ultimately knocked this one off the list.

Equal Exchange Organic Very Dark Chocolate, 71% Cacao (Amazon)
With a name like “Equal Exchange,” this bar wears its ethical sourcing accolades on its sleeve (or rather, wrapper), but it fell short in other important ways. We were unimpressed by the chalky, flat finish. The scent was faint and uninspired, reminding us of mass-produced candy bars. Although bitterness and tannins are something we look for in a dark chocolate bar, this one was overwhelming, reminding us of over-steeped tea; there was also noticeable astringency on the finish.

Taza Chocolate Bars Deliciously Dark 70% (Amazon)
Taza is unique among the bars we tasted in that the brand grinds its cacao on a traditional stone mill. The result is a noticeably gritty texture, which didn’t wow all of us. Fans of fruitier chocolate may appreciate this one, as it ranked low on the earthy scale, but we found the texture to be overwhelmingly distracting when evaluating the flavors.

TCHO Dark Duo 75% (Amazon)
Another unconventional pick on our list, TCHO’s Dark Duo contains two types of dark chocolate: The exterior shell is filled with a creamy, fudge-like center. It has a gorgeously glossy finish and a sharp, fruity scent that will appeal to some, but the ganache-adjacent texture was a bit too far afield from traditional bar textures for us to declare it a winner. Although it’s not quite what we were looking for in this test, if you’re in the mood for a truffle, this fancied-up bar will hit the spot
