For a dark mint with a stated high cocoa content, M&S Collection Dark Chocolate with Mint lists 85% cocoa and 15.6g sugars per 100g, but its allergy warning still needs attention. If avoiding milk and gluten is the deciding factor, look for an explicitly labelled product such as Sainsbury's Free From Dark Chocolate Mints and check the current pack. Treat chocolate mints as occasional confectionery rather than assuming a dark label makes them suitable for a routine school snack, and check the school's packed-lunch policy before sending them in.
Decide whether the mint is for an after-school occasion or a packed lunch. Check its sugar and allergen information, pack format and the school's own food policy. For routine between-meal snacks, Hertfordshire Community NHS Trust suggests options including fruit, vegetable sticks and savoury foods.
If a stronger cocoa flavour matters more than a fondant centre, compare the stated cocoa percentage and sugars per 100g. M&S lists 85% cocoa and 15.6g sugars per 100g for its Collection Dark Chocolate with Mint; Tesco lists 47% cocoa and 49g sugars per 100g for Lindt Excellence Mint Intense.
Choose by the exact product's label rather than the word “dark”. Sainsbury's labels its Taste the Difference Free From Dark Chocolate Mints milk and gluten free, while its Bendicks Mint Collection listing says vegan and Kosher. Check the current pack for the allergens relevant to your household.
Decide when the mints will be eaten, then compare the product label and format against that occasion.
| Priority | What to check | Your needs |
|---|---|---|
| Snack occasion | Check whether the treat is for home or a packed lunch, and read the school's current policy. For regular between-meal snacks, consider the fruit, vegetable and savoury options suggested by Hertfordshire Community NHS Trust. | I want to distinguish an occasional chocolate mint from a regular after-school snack. In the British Nutrition Foundation's 2025 survey of over 2,500 UK children aged 10–13, 76% said they normally snacked after school during the week; 32% named chocolate among foods they ate most often as a snack. Neither figure measures a preference for dark mints. |
| Cocoa and sugar | Compare cocoa percentage and sugars per 100g on the exact product. Marks & Spencer lists 85% cocoa and 15.6g sugars per 100g for its Collection mint bar; Tesco lists 47% and 49g per 100g for Lindt Excellence Mint Intense. | If I prefer a higher-cocoa bar or want to compare sugar figures, I need both numbers from the product I'm considering. A “dark” label alone does not give me either figure. |
| Dietary labels | Read the named allergens and any free-from or vegan statement on the current pack. Do not treat “dark” or “vegan” as a milk-allergy assurance: Marks & Spencer labels its 85% mint bar vegan but not suitable for people with a milk, nut or peanut allergy. | For milk or gluten avoidance, I want an explicit statement for that product. Sainsbury's labels its Taste the Difference Free From Dark Chocolate Mints milk and gluten free. |
| Portion format | Check whether nutrition is given per piece or serving as well as per 100g. Waitrose lists 3.0g sugars per Mint Thin; Sainsbury's lists 17.2g sugars per three After Eight mints. | I would rather decide on a portion than judge a sharing box by its size. Individual wrapping or thin pieces help identify pieces, but do not change the sugar in the amount eaten. |
“Dark” describes the chocolate, not how often the confectionery suits a snack routine. Tesco lists 49g sugars per 100g for Lindt Excellence Mint Intense, while Sainsbury's lists 58.3g per 100g for Bendicks Mint Collection.
Compare the sugar panel and consider chocolate mints as an occasional treat. For routine between-meal snacks, Hertfordshire Community NHS Trust suggests fruit, vegetable sticks and savoury foods.
Marks & Spencer labels its Collection dark-mint bar vegan but says it is not suitable for people with a milk, nut or peanut allergy. Waitrose says its Mint Thins may contain milk and nuts.
Read the current allergen statement for the exact product; use an explicit free-from label where that requirement matters.
Pieces can be individually enclosed while the nutrition figures still refer to several at once. Sainsbury's gives After Eight's sugar figure per three mints, whereas Waitrose gives its Mint Thins figure per thin.
Check the stated serving size and decide how many pieces you intend to serve.
Department for Education school-food guidance addresses food and drink provided in state-funded schools in England. It does not tell you what a particular school permits in food brought from home.
Check the school's current written packed-lunch and allergy policies before including chocolate mints.
Its Dark Chocolate with Mint is a bar to compare if stated cocoa content is the priority.
Mint Intense is a 100g dark-mint bar for shoppers who prefer a bar to fondant-centred pieces.
The Mint Collection is an assorted box rather than a single dark-mint bar.
Mint Thins provide a stated per-piece sugar figure for shoppers comparing portions.
Sainsbury's describes thin dark-chocolate squares with mint fondant centres, each in its own envelope.
These products cover peppermint creams, a multi-pack of mint chocolates and a dark-mint bar. Compare their formats and current pack labels against your intended treat occasion, particularly if sugar or allergens affect your choice.

Consider these if you want peppermint creams rather than a dark-mint bar. Check the current nutrition and allergen label before choosing a portion or serving them to someone with dietary restrictions.

This 120g pack is another peppermint-cream format to consider for an occasional treat. If allergens or sugar are deciding factors, compare the current pack label rather than assuming it matches another peppermint cream.

Choose this format only if six 300g packs suit the intended occasion; it is not a single 300g box. Check the nutrition and allergen information on the packs, and confirm the cocoa percentage if that is central to your choice.

For a mint-flavoured bar rather than peppermint creams, Tesco lists this product at 47% minimum cocoa and 49g sugars per 100g. Its listed ingredients include milk fat and soya lecithin, so check the current pack if either allergen matters.
Do not assume so from the word “dark”: chocolate mints are confectionery, and sugar figures differ by product. For routine between-meal snacks, Hertfordshire Community NHS Trust suggests options such as fruit, vegetable sticks and savoury foods. If you plan to put mints in a packed lunch, check the school's current policy.
No general rule follows from these examples; compare the exact labels. Marks & Spencer lists 85% cocoa and 15.6g sugars per 100g for its Collection mint bar, while Tesco lists 47% cocoa and 49g sugars per 100g for Lindt Excellence Mint Intense. Those figures describe the named products, not every dark chocolate mint.
Sainsbury's labels its Taste the Difference Free From Dark Chocolate Mints milk and gluten free. Read the current package and its full allergen statement before choosing; “dark chocolate” alone is not a free-from claim.
Department for Education guidance concerns food and drink provided in state-funded schools in England; it does not establish what your particular school permits in food brought from home. Check that school's current packed-lunch and allergy policies.
No. Wrapping helps identify individual pieces, but the amount eaten determines the serving to compare. Sainsbury's lists 17.2g sugars per three mints for its 300g After Eight box, so check both the number of pieces and the label's serving size.
