Dark chocolate can be a smart treat when you pick the right bar. Cacao has natural plant compounds, and darker bars usually have less sugar than milk chocolate.
Still, not every bar is equal, and some have been flagged for heavy metals in independent testing. Here are eleven brands to know, with notes on cacao levels, ingredients, and test results.
1. Taza Chocolate

Picture a small mill grinding cacao beans between heavy stones, and you get the idea behind Taza. The company is known for stone-ground dark chocolate, which gives its bars a slightly gritty, rustic bite that many fans love.
Ingredient lists tend to be short and easy to read. That matters if you like to know exactly what is in your snack, since fewer extras usually means less added sugar and fewer fillers.
Because the texture is different from smooth supermarket bars, it helps to taste a small piece slowly. Let it melt on your tongue and notice the earthy, fruity notes.
Pairing a square with almonds or a cup of black coffee can bring out even more flavor.
As with any chocolate, a small portion goes a long way. One or two squares can satisfy a craving without turning dessert into a big sugar event.
2. Ghirardelli Intense Dark

Walk down almost any grocery aisle and you will likely spot a Ghirardelli bar. That easy access is a big plus when you want a better-for-you treat without a special trip to a specialty shop.
The Intense Dark range includes bars with 72% cacao or more. A higher cacao number generally means less room for sugar, and it often brings a deeper, more bitter flavor.
If you are used to milk chocolate, try stepping up slowly. Start with the lower percentage and work toward the stronger bars as your taste buds adjust.
Check the label for serving size, since a bar can hold several portions. Breaking it into squares ahead of time makes it easier to enjoy a modest amount and save the rest for tomorrow.
3. Mast Organic Dark Chocolate

Heavy metals in chocolate have become a real talking point, and Mast gives shoppers a bit of reassurance. Its 80% Organic Dark Chocolate performed comparatively well in Consumer Reports’ heavy-metal testing.
That does not make it a free pass to eat unlimited amounts. Cacao naturally takes up small amounts of metals like lead and cadmium from soil, so moderation still counts.
The bar is also appealing for its strong cacao content. At 80%, it has a bold, less sweet flavor that works well for people who want a rich bite from just a small piece.
Try pairing it with fresh raspberries or a few walnuts. The tart fruit and crunchy nuts balance the bitterness, and the combination makes a simple dessert that feels special.
4. Valrhona

Pastry chefs around the world reach for Valrhona when a recipe needs serious chocolate. The French maker is a premium name, and its products performed comparatively well in the same Consumer Reports testing for heavy metals.
Quality shows up in the flavor. Many bars have layered notes, such as red fruit, roasted nuts, or a hint of spice, which means you may feel satisfied with less.
Price is the main trade-off. Valrhona costs more than store brands, so it works best as an occasional treat instead of a daily snack.
If you like to bake, you can use it in brownies or hot cocoa and get restaurant-style results at home. Store it in a cool, dry cupboard so the texture stays smooth and snappy.
5. Alter Eco

Sometimes a wrapper tells a story, and Alter Eco’s tends to mention how the cacao was grown. The brand offers organic dark chocolate bars with high cocoa percentages, which suits shoppers who want less sugar.
Organic labeling means the cacao was grown without most synthetic pesticides. That is a nice bonus, though it does not guarantee a bar is free of heavy metals, so variety in your snacks is still wise.
The bars come in several flavors, including options with a silky, creamy feel and others with a deeper, darker punch. Reading the cacao percentage helps you choose how intense you want it.
Enjoy a square after lunch as a small reward. Taking your time with each bite makes a modest portion feel more satisfying.
6. Lindt Excellence

Here is a simple rule: the higher the cacao number, the less room for sugar. Lindt Excellence puts that rule into practice with its 85% and 90% bars, which offer more cocoa and less sugar than many sweeter varieties.
These bars taste bold and a little bitter, so they can surprise first-time buyers. Letting a square melt slowly helps the flavor open up and feels less sharp.
Lindt is easy to find in most supermarkets and drugstores, which makes it a handy pick for everyday shopping. Prices are usually reasonable compared with boutique makers.
Try grating a little over oatmeal or plain yogurt for a hint of richness. That way, you get the chocolate flavor without eating a large amount at once.
7. Hu Kitchen

Short ingredient lists make label reading a breeze, and that is where Hu Kitchen shines. The brand is known for dark chocolate products with relatively simple ingredient lists, avoiding many extras found in candy-aisle bars.
Fewer ingredients usually means you can see what you are eating at a glance. For anyone watching additives or refined sugar, that clarity is a real help.
The flavor leans smooth and rich, with some bars including add-ins like nuts or sea salt. Check each variety, since extras can change the sugar and calorie count.
Hu Kitchen often costs more than mainstream options, so treat it as a special pick. Keeping a bar in the fridge can make it last longer and give it a satisfying snap.
8. Pascha Chocolate

Want to cut sugar as far as you can? Pascha has you covered.
The company offers high-cacao dark chocolate, including unsweetened varieties that taste intensely bitter and cocoa-forward.
Unsweetened chocolate is not meant for snacking straight from the package, at least not for most people. It shines when you stir it into recipes where you control the sweetness.
Try melting a little into smoothies, chili, or homemade granola bars. You get deep chocolate flavor while choosing exactly how much sweetener goes in.
For eating on its own, look at the sweetened high-cacao bars first. They offer a gentler path toward darker chocolate, and you can work upward whenever you feel ready.
9. Theo Chocolate

Organic, fair trade, and crafted in Seattle, Theo Chocolate checks many boxes for conscious shoppers. The brand offers organic dark chocolate, with bars that come in a wide range of flavors.
There is one caution to keep in mind. Some tested bars have raised heavy-metal concerns, so it is smart to treat these as an occasional pick instead of a daily habit.
If you enjoy the brand, keep portions small and rotate with other chocolates. Mixing up brands can lower the chance of getting too much of any one metal from a single source.
Look at the label for cacao percentage and sugar per serving. A little attention at the store helps you choose the bar that fits your goals.
10. Green & Black’s

Some bars announce themselves with a bold flavor, and the 85% from Green & Black’s is one of them. It is a high-cacao option, which generally means less sugar than a typical sweet bar.
Consumer testing adds a note of caution. Some tested products have raised heavy-metal concerns, so this one is better as an occasional treat than a daily staple.
You can still enjoy it wisely. Stick to a small serving and vary your chocolate choices over the week.
The taste is rich and slightly fruity, with a firm snap. Serve a square alongside fresh strawberries or a warm cup of tea for a calm, slow dessert that feels like a small ritual.
11. Lily’s

Curious about chocolate without the usual sugar? Lily’s built its name on that idea.
The brand offers no-added-sugar dark chocolate, sweetened with alternatives to conventional sugar.
That can appeal to people who are watching their sugar intake. Sweeteners vary, though, and some people find certain ones upsetting to their stomachs, so try a small amount first.
There is also a testing caveat. Some tested bars have raised heavy-metal concerns, which is a good reason to keep portions modest and rotate brands.
Read the label closely, since sugar alternatives and cacao levels differ from bar to bar. If it fits your needs, a square or two can be a pleasant way to end a meal.
